 | Hi there my computer refused to power up recently The fans started spinning the lights came on but I had no beep codes and nothing on the screen not even the post screen. I needed a new comp quickly and so got a new motherboard,Ram and CPU. Once plugged in … |
| | Hi there I am writing a game with some basic AI elements. The enemies know there position and the players position and so are able to rotate and follow the player around etc. The idea is that when an enemy gets within a radius of the player they calculate a … |
| | Hi there I'm not to sure if this should go here or in games development so please move it if required. I'm trying to make a basic function that allows my character to jump. The basic idea is to check if the character height is equal to that of the … |
| | Having nothing in the brackets comes in useful if you wish to draw something directly to the screen and no input is needed. It allows you to write an algorithm that steps through a process and then call it as many times as you want. There maybe several different occasions …  |
| | Hi there My computers PSU recently died. So I replaced it and all seemed ok. My computer has now started to randomly freeze,hang or run really slow. I figured this may be a HDD problem, I used the chkdsk and it found 4KB in bad sectors. I tried to clean …  |
 | Re: 2D OpenGL within the main display loop you can simply change the projection to orthographic. A tidy way is to input a class that has the code neccessary code to generate the 2D projection matrix and neccessary screen co-ordinates. you can then write the commands to draw the objects in this class. … |
| | Hi there I am currently writing this on my mobile phone so apologies for any mistakes. My computer has been running fine for 2+ years until the other day when it froze and stopped responding. I thought nothing of it and rebooted, it crashed again so I did a harddrive … |
| | Hi I wasn't sure if this was the right section or not How is a GUI implemented in modern operating system. Currently I use win32 code to generate a window and then use openGl with C++ to generate the application. How is explorer.exe (the windows interface) designed and built. Does … |
| | It sounds like it possibly is the video chip. If you heat the chip with a hair dryer I don't think it would work for very long after. The theory is that you can heat the chip to try to re solder it back to position and get a good … |
| | Hi there I am having a frustrating and strange problem. I am building a particle system. As a result I need particles to reset there variables to be reintroduced into the system. I have had it working in the past. I run through the system once, when the particles pass … |
| | Matlab is good for matrix manipulation and general math. Easy and quick to implement items and quite intuitive, it does differ quite dramatically from other languages such as c etc but worth a look. Only really good if performance is not a main concern as it does have a habit …  |
| | Hi This might sound like a really stupid question but what gain do I get for using pointers? I use pass by reference and have used pointers a lot but have never really thought of the actual saving achieved by doing this. I have just been taught that using pointers … |
| | Hi I am currently primarily programing graphics applications and am still fairly new to this. I know the relevance and can see the advantages of making items a template especially with things such as collision detection. I was wandering is there any advantage/disadvantage to doing everything as a template? Obviously … |
| | Hi there I was wandering how a virtual Os exactly works and if it is classed as easier or harder then building a kernel for a normal OS? I have read briefly about having virtual hardware and having to create additional files etc. I have also read about creating one …  |
| | Hi there I have been building a program separately and testing the code in sections. Which is fine as it works individually. However two of the classes are designed to share variables. The idea is the first class generates a partcile and then scans through a list of gridCells. It …  |
| | Hi there I am developing a grid system that would generate non-overlapping grid cells. Upon creating a grid I want to be able to check to see if the potential grid overlaps any other grid cells. If it does then clamp the new grid cell to the already existent grid. … |
| | Hi there I am not sure whether to put this here or in the games development section I do apologies if it is in the wrong the section. I have an object with a bounding box around it. I want another object to then be able to send a ray … |
 | Using openGL with glut or win32 code to generate a window would help with the problem. I would recommend looking at [url]http://nehe.gamedev.net/[/url] it has some very useful tutorials especially if you have never coded any graphics.  |
| | Hi not sure if its exactly what you mean but 3DMARK runs tests on the GPU and CPU and then gives it bench rating. You can compare these on line to see how good it is. It runs stress tests in various different ways to analyze different aspects such as … |
 | When several processes are waiting for another to finish so none do. Livelock can also occur and is the opposite When two processes constantly give each other access so neither get the resources required.  |
| | C++ is one of the more widely used languages for developing games rules and keeping track of variables setting up collision detection etc. DirectX librarys or openGl, openAl and openCl can then be used to render items to screen, load sound files and allow for parallel processing to increase speed. … |
| | Re: Pygame Bullet You should know where the plane sprite is in space through the translations that have occurred. If you generate the bullet at the planes co-ordinates and then move it to the specified place to shoot from (i'm assuming the wing). If the plane sprite is a 1X1 square for example … |
| | Hi I am looking at using octree data structures to optimize collision detection. I can see how it can be used to replace a normal grid. How does it work around an object? I have created AABB boxes that move and update there co-ordinates alongside an object correctly. The way … |
| | Hi there I have made and run several different graphics programs and applications. The applications I have made so far always use the full processor and graphics card available. The game for instance may run at 5000fps or some really high number. I am assuming this is not how games … |
| | It depends what you want to do really. I found physics useful for graphics applications, allowing for character responses etc. I noticed you haven't included math? Is that compulsory or not? Pick the one you feel most comfortable with.  |
| | Hi there Sorry wasn't to sure where this was supposed to go. I am interested in the lower level of computing and was wandering how to build a language, or program such as visual studio? I have gathered it goes from the higher language and gets compiled into assembly/machine code …  |
| | Hi I haven't had much experience of Matlab but I have used it for image compression and sound recognition before. I'm not sure if it comes under the functional programming catogery. It works with matrices and is effectivly a large calculator that is great for working with math problems. Initially … |
| | Hi there I am building a 3D game in C++ and openGl I came to do a full test of my game the collision detection and things are finally approaching working fully. When I run it it becomes very memory hungry and eats a few Gb of Ram and crashes … |
The End.
