How to write text to glut window with the keyboard in c++?

bushimports — Sat, 07 Nov 2009 23:25:44 GMT

How can I draw text in a glut window with the keyboard;
I have tried doing cin with

void TextBox::Keys(unsigned char key,int x,int y){

   switch(key){

      case 13://enter key

      cin >> String;

       DrawString = true;

      break;    

      case 27:

        exit(0);        

      break;                    

   }

and then in the draw function

          fontx = tx + 3;

          fonty = ty + (th+8)/2;

         if(DrawString == true){

         glColor3f(0.0,0.0,0.0);               

         Font(GLUT_BITMAP_HELVETICA_12,(char*)String,fontx,fonty);

}

the intention here was to get the string from cin and put it in the string variable and then draw it to the screen. I know how to get
input with cin and put it in a variable with a console program, but i don't know how to do it with the glut keyboard. I also know how to draw text to the screen with glut. I have other questions but I will post them in seperate threads. Much thanks, Jody Bush

Searching for coders

mancent — Sat, 07 Nov 2009 19:03:13 GMT

Hello every one. I would like to ask any one who is able to code c++ if any one would like to work on a new code for a new or old game Final Fantasy XI.

Projectxi.org is doing some good work, but could really use some help from you guys, and it would be a honor to have some of your help. We have a massaive lagg issuse and our conectioion is only letting us allow 9 players to play on one server. So I thought It would be a good idea to ask you for help.
But if your willing to just check out the code and maybe post some ideas at projectxi.org for help This would be very awsome.

Problem with DirectX3D initiation

FrozenSnake — Thu, 05 Nov 2009 21:29:30 GMT

I try to split up my DirectX stuff and GUI stuff into two classes. It has come to the part where it compiles, but this snippet return false:

if(FAILED(pd3d->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hwnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dpp, &pd3dDevice)))

{

        MessageBox(NULL, "CD failed!", "Fatal error!", MB_OK);

        return false;

}

It is part of the class DxManager, I think it's the hwnd that fails. hwnd is part of the Gui class

Here is the Gui class

class Gui

{

public:

        Gui();

        virtual ~Gui();

        bool InitWindow(HINSTANCE hInstance);        

        static LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

protected:

        HINSTANCE        hInstance;

        HWND                hwnd;

private:

        int                        width, height;

};

and here is the DxManager class

class DxManager : public Gui

{

public:

        DxManager();

        virtual ~DxManager();

        bool InitDirect3D();

        void StartRender();

        void StopRender();

        void CleanUp();

        void BlitToSurface();

private:

        bool fullscreen;

};

Anyone that can help me understand what is wrong?

News Story FIGHT: World of Warcraft vs China

happygeek — Tue, 03 Nov 2009 14:04:15 GMT

It would seem that there is something of an ongoing battle in the world of online Chinese gaming, and World of Warcraft is right in the midst of it.

As I reported back in July, the company behind World of Warcraft (Blizzard Entertainment) was having problems in getting The Burning Crusade expansion pack up and running in China. Best not even mention Wrath of the Lich King then. It's all a little, well a lot, complicated and just a tad political, of course. Here's what I said a few months ago:

"A planned upgrade to the game which involved moving to a new operator in China, an online gaming outfit by the name of NetEase, has been anything but easy. Because it is a foreign game, and the move to a new local operator makes it a new foreign game for good measure, the Chinese government get to put it through a strict approval process."

Now it would seem that the publishing regulator in China has returned that application and halted the approval process as a result. NetEase, meanwhile, has already started operating World of Warcraft in China again despite not having approval. It fired up the local WoW servers back in September, one assumes as it was tired of waiting for that bureaucratic rubber stamp. Remember, WoW had already been approved and had been operating in China previously, all that changed was the local operator. Heck, NetEase apparently even got the nod to go ahead from the Cultural Ministry in China to rev up the WoW servers again.

But that has not appeased the agency concerned with the approval process, the General Administration of Press and Publication (GAPP) and it has now demanded NetEase stop taking money, stop new players from signing up, and in effect just, well, stop. No doubt part of this intransigence stems from the declared intent of GAPP to clean up the online gaming sector and remove violence and pornography from the MMORPG genre (oh how China loves those weapons of mass censorship) but it will be interesting to see how the war is won between commerce, a Government with one eye on foreign investment and an internal agency seemingly struggling to justify its own existence.

pygame and livewires, small problem

Garrett85 — Sun, 01 Nov 2009 20:21:44 GMT

I am reading the book "Python Programming 2nd Ed. for the absolute beginner" and I am having some trouble with a very simple program. I was instructed to download and install pygame and the livewires package as I have done. This program is meant to display a grahical window, that's it. But I'M getting the following error with the following code.

AttributeError: 'module' object has no attribute 'init' on line 6

# New Graphics Window

# Demonstrates creating a graphics window



from livewires import games



games.init(screen_width = 640, screen_height = 480, fps = 50)

How to get Maya to replace a directory with an environment variable?

Morika — Tue, 27 Oct 2009 23:20:55 GMT

Hi,

I'm trying to work out how to get Maya to save out my environment variable as opposed to the full directory. I have changed my maya.env file so it has no trouble reading the environment variable and then writing out the environment variable if it was already written out in the maya ascii file.

The thing is when I'm in Maya and I pull in another jpeg, or tif file it automatically writes the whole directory out and not the environment variable.

How can I get Maya to aggressively replace my directory and write out the environment variable every time?

Thanks,

Graphics on multicores

Mohamad89 — Mon, 26 Oct 2009 16:23:12 GMT

Hello,
I am currently doing a research at my university about the ways in which we can use multicore CPU to enhance graphics performance instead of putting all the load on the GPU, I am trying to work with both OpenGL and OpenMP and I am planning on using gDebugger to measure performance but I am stuck due the lack of information and papers about this subject so if anyone has any knowledge or any contribution or suggestion please do let me know.

Thanks.

OpenGL rotations

sfuo — Fri, 16 Oct 2009 22:10:14 GMT

I am making a rubix cube game in OpenGL and I have run into a problem with rotations. When doing multiple rotations (x, y, z) the axis gets rotated as well (ie when doing an x-axis rotation of 90 or 270 deg the y-axis becomes the z-axis and z-axis becomes the y-axis).
Is there any way to stop the axis from rotating but allowing the object to translate or is there a trick to get around this.

Here is a small part of my code for the translations.

glPushMatrix();

        glRotatef(xrot, 1.0, 0.0, 0.0); //rotates the unit cube into place

        glRotatef(yrot, 0.0, 1.0, 0.0);

        glRotatef(zrot, 0.0, 0.0, 1.0);

                

        glTranslatef(xoff, yoff, zoff);  //translates the unit cube into place

                

        glRotatef(xrotset, 1.0, 0.0, 0.0); //rotates the unit cube in its place 

        glRotatef(yrotset, 0.0, 1.0, 0.0);

        glRotatef(zrotset, 0.0, 0.0, 1.0);



        glBegin(GL_QUADS); //draws the cube

                for( int i = 0; i < unitIndices.size(); i++ )

                {

                        GLint *curIndices;

                        curIndices = unitIndices[i].getVals();

                        glColor3fv(unitColors[i].getVals());

                        glNormal3fv(unitNorms[i].getVals());

                        glVertex3fv(unitVerts[curIndices[0]].getVals());

                        glVertex3fv(unitVerts[curIndices[1]].getVals());

                        glVertex3fv(unitVerts[curIndices[2]].getVals());

                        glVertex3fv(unitVerts[curIndices[3]].getVals());

                }        

        glEnd();

glPopMatrix();

This is just how I have the drawing for each unit cube 27 of these make up the "rubix cube". The problem lies in the xrot, yrot and zrot lines.

Thanks.

Camera witha a large field of view

sjcomp — Wed, 14 Oct 2009 13:38:46 GMT

Hello,

In my program I have clipping planes setup for 60 degree field of view. I understand that near plane is in front of the camera and the far plane is further away from the camera. I would like to have a large field of view, let' say more than 200 degrees (the most I can go of course is 360, of course). But anything starting with 180, makes the far plane to be behind the Near plane. How should I set the transformation matrix for large FOVs? Anyone had experiences with that?

Thanks.

DirectX 10 slow? alternatives?

athlon32 — Tue, 13 Oct 2009 02:58:09 GMT

I know a little DirectX 9(I can draw a little, etc.), but i want to learn DirectX 10. I decided to take the tutorial that is provided in the DirectX SDK, so i did.

Almost immediately i noticed that it was heavy. My CPU usage shot up and it took much longer to load than DirectX 9. The second example (drawing a simple triangle) took over twenty seconds to complete! My PC ain't the 'newest' so to speak, so i can see why i seem to be encountering these problems.

So what I'm asking is this: What can i do to make DirectX 10 work more smoothly on my rather weak PC? and what is the best alternative to DirectX? maybe OpenGL?

mapping 2d image to a shape

fallopiano — Thu, 01 Oct 2009 03:00:36 GMT

hello everyone. Right now i'm currently working on a 3d engine in python and pygame. it supports images that can (will) be mapped and transformed to look 3d. in pygame, you can load your basic image, do rotations and scales, etc. But the only thing it lacks (perhaps b/c it's more advanced) is mapping images to a shape. In short, would anyone know how to go about taking image data and then mapping it to a shape (any formulas?)? any help/suggestions would be appreciated!

opengl spritesheet help

junioryz — Wed, 23 Sep 2009 13:47:41 GMT

If possible could you please take a look at this image/tileset and see if its possible to draw a 2x2 tile map with each of the frames in that image correctly mapped onto the quads in the tile map.

The idea is to go on and use this as a spritesheet or/and tileset, to basically cut out ANY PORTION (or frame) of a single texture.

The image : http://img441.imageshack.us/i/tileset512.jpg/

This is all in 2D, the formula i use gets me the frames in the wrong order (draws from BL to TL, then BR to TR) so if anyone can help i'd appreciate it and note i'm NOT ane expert with opengl lol.

So my 2x2 tile map should look EXACTLY as that image!

Also! If by some magical way the texture coordinate system can be modified to start with 0,0 at the top left then i'd be fine as i only get the correct coordinates from the texture starting at 0,0 where thats the bottom (BL) when i want (TL).

Thank You

3D Educational MMO's

Hello!

I'm a management major doing some research on educational video games: Just wanted to ask if you have any good sources/references/insights/anything interesting about video games being used in education? especially in the collegiate level.

Things I want to find out are:

>The usual target segment for these games have been children, are there games that are educational that are targeted for a mature/college-level audience?

>How has the educational games market been doing? Do teachers really use it? Would you use it to teach college students?

>Are there any MMO(Massive Multiplayer Online) educational games?

>How about Online Classrooms similar to video games?

>anything interesting/ keep in mind about either or a combination of 3D/MMO/Educational Video Games

Im looking for really good material :) The end project is i'll be doing a sort of 3D MMo educational videogame using the projectwonderland engine, im doing the background of the study.

Thank you so much!

I need a little advice...

Kairu — Sun, 13 Sep 2009 17:25:04 GMT

So. I've decided to make a browser based MMORPG. But I need some advice on where I should start with the whole thing...
I've got ideas, and knowledge on HTML, CSS and JavaScript. From what I've found PHP and MySQL is needed also, and I know very little on them, so what is it about these two I need to know? What are the important parts that'll make it come together?

If it's any help, the game is a basic text based, it's mainly clicking links to make stuff happen, to buy items, fight, etc. I'd like the ability to buy and build property also. As I say, nothing big (idea wise). It will have a few graphics also.
What I need to know, if it wasn't very clear before: What parts of PHP and MySQL are vital? Why do I need PHP and MySQL? And where should I start?

Thanks for all help! :)

Understanding coordinate space in OpenGL

acidnynex — Thu, 10 Sep 2009 18:33:54 GMT

I'm having trouble understanding coordinate space using perspective in OpenGL. Basically I can't figure out how many units will represent the entire screen given a specific z-value or how spacing should be done, etc. In all the tutorials I've seen they plot these nice shapes placed evenly apart in different areas of the screen x units back in the z-plane but I have no idea how to inherently understand how many units I have to work with at that z-value and how to space things, place them, etc. Is there a good primer on this or some formula using something like the fov angle, viewport size and camera position to figure these things out? Recently I was asked to plot two dots in perspective 1 inch apart on the screen and I'm having trouble figuring out how to achieve this (1280x800 10" monitor display).

where do i start?

MattyRobot — Sun, 06 Sep 2009 15:14:12 GMT

I have recently learnt the basics of c++ but I want to advance to making proper GUI's (and games) but I don't know what to use.

Moving objects in OplenGL using glu

Hi every body,

I am coding in cl-glfw (a binding OpenGL for Common Lisp). I handle with moving objects on the screen using mouse. Because cl-glfw doesn't bind glut, it is difficult to interact to mouse, keyboard.

Are the any people developed with cl-glfw? I need to discuss about moving object using mouse. We just use gl and glu library without glut.

A little help with scrolling tile based collision.

Pikachumanson — Mon, 31 Aug 2009 02:30:17 GMT

I am working on a 2-d scrolling map RPG ala final fantasy. Anyway the question I wanted to ask you is how do you go about tile based collision? Let's say I got my scroll map made up and I don't want my player to walk over tiles assigned to ten and twelve. How would I go about doing something like that?

I asked my professor about this and he told me this:

You could create a two dimensional array of RECTs that map to the tiles. Then you could check for collision between the player and the RECT by looping through the two dimensional array.

I'm not understanding what he means by this. Could someone show me an example what he means by mapping the Rects to the tiles and looping through the dimensional array? I don't any experience with working with scrolling tile maps so any help would be appreciated. Oh yeah, and before anyone says anything I already asked him this question he hasn't gotten back to me yet.

RAMP GAME

ammadkhan — Sat, 29 Aug 2009 11:21:14 GMT

--------------------------------------------------------------------------------

HELLO FRIENDS...
I M MAKING A GAME WHICH IS CALLED "RAMP GAME".
THIS GAME CONSIST OF
1) A BALL, 2) A BASKET, 3) SOME LINES ( which can be place anywhere by the user with in the boundary walls).

HERE IS TEH LINK....
SNIP
u can see what it looks like....

now what i m here for?....is i dont know how to bounce a ball w.r.t the collision angle..... i don't know how to move lines at run time.....
i should no my problems here, so u can understand what i m trying to say...

1) Setting the lines at run time.
2) When ball collides with the lines then it should reflect w.r.t the angle of
reflection.

ONE MORE THING......there is a restriction that the game should be made on "OPENGL".

PLEASE HELP ME OUT WHO KNOWS OPENGL.......

Direct3D9 Sprites + rotation

gotnoname — Fri, 28 Aug 2009 03:00:35 GMT

Hi. I initially started up a thread at the Game Dev. section of the forums but it seems rather dead so I thought I'd try my luck here.

I am making a top-down 2D shooter in D3D.
So what I want to do is have my character rotate towards my mouse icons. So that means there are 2 vectors involved, pos and mousepos. So I calculate the angle and then rotate the sprite towards the mousepos. It rotates towards the right direction but when the sprite rotates it isn't centered.

The center at which it is being rotated around looks to be the actual position, and this goes hand in hand with where it initially is drawn which also is wrong.

Lets say I paint it out at (10,10) (x,y) in pixels. Then I move it to (10,0). It is now outside of the picture but when I rotate it 180 degrees it is painted slightly below (10,0).

I initially create my texture with the D3DXCreateTextureFromFileEx function with width and height at D3DX_DEFAULT_NONPOW2 so that isn't something causing the off-centre behaviour.

So I'm thinking that it is a logical error with my drawing function and would appreciate any additional insight.

I tried different ways of doing the Matrix such as D3DXTransformation2D function aswell as moving it before rotation/scaling and moving it back to finally move it where it belongs.

This is how my drawing function looks like atm:

Matrix transform, scaling, rotation, translation;

D3DXMatrixIdentity(& transform);



D3DXMatrixScaling(& scaling, Surf->getScaleRateX(), Surf->getScaleRateY(), 1.0f); 

D3DXMatrixRotationZ(& rotation, D3DXToRadian(Surf->getRotationAngle() ));



Vector2D hotspot = Surf->getHotspot(),

position = Surf->getPosition();

 

float        x_Adjust = position.x + hotspot.x,

        y_Adjust = position.y + hotspot.y;

 

D3DXMatrixTranslation(& translation, position.x, position.y, 0);

 

transform = scaling * rotation * translation.

 

hr = m_Sprite->SetTransform(& transform);

 

if(FAILED(hr) )

{

        m_lastError = hr;

        return false;

}

 

hr = m_Sprite->Draw(        Surf->getTexture(),

                        PartOfPicture,

                        & Surf->getHotspot(),

                        NULL,

                        D3DCOLOR_ARGB(Alpha, R, G, B) );

 

if(FAILED(hr) )

{

        m_lastError = hr;

        return false;

}



return true;

Pirate Themed 2D MMORPG: Game Tools!

Zenpher — Thu, 27 Aug 2009 21:13:30 GMT

A few friends and I have been working on an isometric MMORPG called Pirate Story Online. It's basically just a simple 2D MMO with a very heavy emphasis on humor and eye candy.

We're currently developing the client in Python, the server in C, and we're using a MySQL database to store user information.

What we're looking for is a pretty easy going programmer for programming our game tools (map maker, sprite editor, NPC editor, etc..). We do have a fairly simple mapping program (quite crude atm!) and some features that already work (such as a centralized tile database on our server that updates map editors automatically) but we really need some heavy duty development in that area.

We prefer someone who enjoys working with Python, but either way, we really don't mind (C++, Visual Basic, heck even PHP is alright!). We just need someone who is capable of getting together a simple set of tools for windows.

Here is our project homepage:

http://piratestoryonline.com/

You can also add me on MSN:

ryuman313_101@hotmail.com

-Thanks for looking guys, we really appreciate it :)

Strange issue with drawing simple 3D shapes

Yle — Tue, 25 Aug 2009 16:59:33 GMT

I've gone a little further with my code since the last time I posted here. Everything worked fine till the moment I started drawing in an actual 3rd dimension - the results are visible at least, but they're far from what they should look like. Instead of a pyramid and a cube I get two more or less randomly combined surfaces. Tried rechecking and playing around with cords, without effects.

Remove Glut maximize window button / option

dark_lord — Mon, 24 Aug 2009 12:54:14 GMT

I am using glut to create my window for my game. My question is how do I remove the button that maximizes a window. For my game I don't want the player to be able to resize or maximize the window. Is there a way to control this with glut?

Thank you!

OpenGL - displaying issue (reshape func)

Yle — Sat, 22 Aug 2009 23:22:25 GMT

Hello,
my problem is of that kind beginners use to have. After following some glut tutorials I've decided it's time to do something small generally on my own. An obstacle appeared at the very beginning.

At the moment I got stuck, all my code was supposed to do was drawing a primitive using an ortagonal transformation to display it. Apperently, I failed at coding the latter.

void reshape (int w, int h)

{

     if (h==0)

     {

              h=1;

     }

     

     glViewport(0,0,w,h);        

     glMatrixMode (GL_PROJECTION);

     glLoadIdentity();

     

     glOrtho(0.0f,w,h,0.0f,-1.0f,1.0f);        

     glMatrixMode(GL_MODELVIEW);

     glLoadIdentity();

}

and the drawing func("bobby's" variables x and y are holding float values, tried with various bare numbers too):

void DrawScene(void)

{ 

     glPushMatrix();

     glTranslatef(bobby.x, bobby.y, 0.0f);

     

     glColor3f(1.0f, 0.0f, 0.0f);

     glBegin(GL_TRIANGLES);

     

     glVertex2d(-0.2, -0.2);

     glVertex2d(0.2, 0.2);

     glVertex2d(0.2, -0.2);

     

     glEnd();

     glPopMatrix();

     glutSwapBuffers();

}

Guess I could solve this with a little help of an example code, but I'd like to understand what I'm doing. Thanks.

falling of a bmp under gravity - glut

dark_lord — Fri, 21 Aug 2009 11:26:31 GMT

hello dear users..

i am working on a simple 2d game like DANGEROUS DAVE (if anybody played he will know better)... i was working fine although i am new to openGl and glut... now there is a problem that i want my character ( in fact a bmp image) when collide with a rectangle shape it falls back to ground under gravity.. i didn't get any helpful resource yet.. could anybody help me please as i have to submit my assignment really soon..
if anybody want more explanation or my code i am ready for that..
thanks in advance...!
waiting anxiously for your kind replies...!

Okay so please do not ask about the shader code cause it is set up properly. I am getting a runtime error saying:

Unhandled exception at 0x00000000 in prog.exe: 0xC0000005: Access violation reading location 0x00000000.
this happens whenever I am trying to call the glew function glCreateProgramObjectARB... Not sure what is going on and any help would be great

Direct3D9 Sprite issues with rotation.

gotnoname — Sun, 16 Aug 2009 03:06:49 GMT

Hi I am making a top-down 2D shooter in D3D.

So what I want to do is have my character rotate towards my mouse icons. So that means there are 2 vectors involved, pos and mousepos.

Now calculating the angle wasn't a problem but the problem comes when I try to rotate around my sprite towards the angle.

It rotates towards the right direction but when the sprite rotates it isn't stuck at it's position.

The center at which it is being rotated around looks to be the actual position, and this goes hand in hand with where it initially is drawn which also is wrong.

Lets say I paint it out at (10,10) (x,y) in pixels. Then I move it to (10,0). It is now outside of the picture but when I rotate it 180 degrees it is painted slightly below (10,0).

So I'm thinking that it is a logical error with my drawing function and would appreciate any additional insight.

This is how my drawing function looks like atm:

float        fix_x = 0.5f;

float  fix_y = fix_x;



Matrix transform, scaling, rotation, translation;

D3DXMatrixIdentity(& transform);



// fix for rotation

D3DXMatrixTranslation(& translation, -fix_x, -fix_y, 0);

transform                = translation;



D3DXMatrixScaling(& scaling, Surf->getScaleRateX(), Surf->getScaleRateY(), 1.0f);



D3DXMatrixRotationZ(& rotation, D3DXToRadian(Surf->getRotationAngle() ));



transform        = transform * scaling * rotation;



// move back after rotation

D3DXMatrixTranslation(& translation, +fix_x, +fix_y, 0);

transform        = transform * translation;



// Translation

Vector2D        hotspot = Surf->getHotspot(),

                position = Surf->getPosition();



float                x_Adjust = position.x,

                y_Adjust = position.y;



D3DXMatrixTranslation(& translation, x_Adjust, y_Adjust, 0);



transform                = transform * translation;



hr = m_Sprite->SetTransform(& transform);



if(FAILED(hr)  )

{

        m_lastError = hr;

        return false;

}



hr = m_Sprite->Draw(        Surf->getTexture(),

                        PartOfPicture,

                        & Surf->getHotspot(),

                        NULL,

                        D3DCOLOR_ARGB(Alpha, R, G, B)  );



if(FAILED(hr)  )

{

        m_lastError = hr;

        return false;

}



return true;

Multiple DirectX .x files from Dark GDK

C++ Obliviator — Fri, 14 Aug 2009 16:19:21 GMT

I'm creating my first FPS game,
in MS Visual C++ 2008 Express Edition with Dark GDK.

I've created a level and so on, and now I'm updating my enemies.

My ninja enemies have different .x files for different states, example: one for idle and one for attack.

I can't manage the switching between the different states! :(

Here is my code:

void updateNinja ( void )

{

        int iLoop = 0;

        float distCameraNinja;

        

        for ( iLoop = 0; iLoop < ninjaCount; iLoop++)

        {

                if ( ninja[ iLoop ].life > 0 )

                {

                        switch ( ninja[ iLoop ].mode )

                        {

                                case 1 :        // idle                loop idle & check dist

                                        {

                                                if ( ninja[ iLoop ].type == 1 )

                                                        dbLoopObject        ( ninja[ iLoop ].obj , 0 , 0 );

                                                else

                                                {

                                                        dbDeleteObject        ( ninja[ iLoop ].obj );

                                                        dbLoadObject        ( "media\\H-Ninja-Idle.x" , ninja[ iLoop ].obj );

                                                        dbLoopObject        ( ninja[ iLoop ].obj );

                                                        ninja[ iLoop ].type = 1;

Can anybody help me?

Are there a better way of switching than deleting the current object and load a new object with the same object number?

Please help

Web based game Java???

PeteRico — Thu, 13 Aug 2009 18:31:46 GMT

I am developing an app and was wondering if any software might exist to help.

Specifically, I want a simple app that will allow me to take a video or pics of a neighborhood. If possible, I would like software to convert the neighborhood to a 3d cartoon-ish (not absolutely required) format. <--- only used to set up in advance and not for the user. A convert once.

Next I want the user to select a character that can run around the neighborhood and walk up to any door. At the point they arrive at the door, I have another piece of software that will take over.

Simply, a neighborhood where a character can walk or run.

Is there any software that will help create this? It needs to run within a web browser for a desktop, PDA (including Ipohone and blackberry and palm pre).

Thanks in advance.

Confused!!!

Hi all,

Well i am new to game development. i am a CS guy, i am quite good at c/c++. but i wanna develop game on Microsoft .net (C#)Platform.
I read through a XNA review. Reviews say that, u cannot develop 3D game on XNA. i am totally confused about game development.

when u hav C#, xna, Direct X and other good IDE/APIs. why do u need to go for a game engine. Now, could someone please guide me through this. And how do u develop one!!

D3DXFrameCalculateBoundingSphere with progressive meshes

dipunm — Tue, 11 Aug 2009 14:15:38 GMT

I am working with Direct3X 9. In order to improve performance during runtime, I have been working to create progressive meshes using D3DXGeneratePMesh().

So far so good, the mesh was created and there were no errors throughout the application. HOWEVER, the model was not displaying on the screen. After a long debug process, I found the error to be in the D3DXFrameCalculateBoundingSphere function. If I remove the convertion into a progressive mesh, it works fine, but after converting, the function returns a 0 center and 0 radius but returns S_OK.

This to me assumes that it does not find any meshes whilst traversing the frame structure. Does anybody know why this would be?. Any meshes converted to PMesh has the meshData.Type set to D3DXMESHTYPE_PMESH so there should be no confusions.

If there is need to see source code, let me know which bits you need. Thanks,

Dipun
