So I'm writing a memory pool allocator template where it assumes all the objects are of constant size. I need it for a couple objects in a game i'm writing because the dynamic allocation of a large number of small objects is more slow than i'd like. My issue is …

My question is basically if I have a 4D vector like _declspec(align(16)) class Vec4 { float x; float y; float z; float w; } and I want to use operators like `Vec4 a(Vector4.One),b(Vector4.One),c(Vector4.Zero);` `c = a + b; //Creates a 4th Vector4 here that is wasted` It would seem it …

Hey guys :D I want some opinions on a few queries I have. Some background info: I'm adept at programming in VB, C++ and somewhat less experienced with Java and C#; considerably experienced in 2D graphical design; and I'm studying a minor course in game design and also game development. …

So am doing a run down of different 3DMath Libraries. I am noticing functions with return types are HORRIBLY inefficient compared to void returns. I decided to do a rundown of how move constructor/assignment effects this. Well having a move constructor is seeing an average of 3.5-4x improvement, but doing …

So in my scripting project I mentioned yesterday I was thinking about how to implement arrays. That got me to thinking how does c++ get arrays and inherited classes to interoperate and found out some wierd things class Y { public: int A; Y() { A = 0; } }; …

long FileSize(FILE* f) { if(f) { long size; long initpos = ftell(f); fseek(f,0,SEEK_END); size = ftell(f); //Get End Position Which fseek(f,initpos,SEEK_SET); //Go Back To Initial Position return size; } return 0; } Only 183 characters in text file but reports 197. Reason for this?

Whole purpose of learning C++ over C# and whatnot is for performance and working at a lower level for more control. Since I've been learning a little SIMD I figured a good project to test myself and make stuff better would be to program a basic scripting language that handles …

Well been working on a project that has a bit of sandbox approach to building things. It works pretty well, but I want users to be able to implement C# script for the objects or to keep track of them and perform analytics. I have got it somewhat working as …

I know C/C++ but am trying to learn C# as creating GUI based application is much easier than in C++. I've been leveraging the options of which GUI tool I should learn. Is it best to learn Winform, WPF, or other? I recently tried out the Windows 8 preview to …

The below code gives an output of: [CODE] Allocated! Allocated! Deleted! Allocated! Allocated! Deleted! Size: 3 Capacity: 4 vector[0]: isAligned! 20 30 40 Deleted! Deleted! [/CODE] Can someone explain the first allocation and why there are 4 allocations instead of 2 (one for each reserve?). I figure the first is …

So going over the new DirectXMath and loving how it has better documentation then the old versions, but anyways. It makes a note on many of its targets need to have aligned memory blocks, but that throws me for a loop because I don't know of a way to declare …

Alright I've been writing C/C++ code for a few years but recently got into helping make an indie game with a few guys. We are scripting in C# but i'm just a bit lost on how to do some stuff without pointers. Its a generic class that holds the non-work …

So need to use C# to create this tool I want for a game. It will involve an interop between Excel and my own program so I can easily tweek values on some items in my program or through excel. So far it's going ok, but when I'm constructing the …

So I'm beginning to use JavaScript with a new gaming platform I'm trying out and LOVE the interface. It's making everything so easy compared to the in the garage type setup I'm used to. Learning JavaScript has been pretty easy so far but I've hit a snag with typeof. [CODE] …

Hey guys! I hope what I'm about to do is not frowned upon :) I just would like some input/critics/heads up on my class definition and implementation I did for my project. I am by no means a trained programmer and I doubt my coding style is very good so …

So I've created an event driven architecture for my current program. I want each new event to have a number generated automatically with a function so I don't have to worry about overlap of id's and referencing is easy. [CODE] class Event { protected: static int get_event_id(); public: virtual int …

I get this warning and I can't seem to figure out what it is referring too (it repeats this exact one ALOT when i have very little code). I'm trying to implement boost archive into my project as it allows less code to be written when serializing classes. [CODE] c:\program …

[B]Beginner's guide to C++0x: Avoiding Memory Problems by Design of Ownership[/B] If you ever read any resources on C++ programming or object-oriented programming, you must have heard some rethorics like "inheritance is for the [I]is a[/I] relation, composition is for the [I]has a[/I] relation". Is that all? Is that the …

My current project requires quite a bit of function pointer passing to guarantee the flexibility desired. Given how messy and annoying I find functions pointers to be I decided to create a wrapper class listed below. Works fine, however it would be nice if their was a method so I …

Sorry if this might be a stupid question, I'm still new, I've been doing C++ for 3 days so far and I just reached objects.. Anyway. I made one thing to additionate seconds with seconds, minutes with minutes and hours with hours. The thing compiles but crashes as soon as …

This is what I read about it. [CODE] virtual base class becomes common direct base for the derived class [/CODE] So my question is exactly what does this mean. What I believe it means. [CODE] class A { protected: int a; public: virtual int get_a(); A(void); ~A(void); }; [/CODE] With …

All right, I am trying to make a working healthbar for my game done in direct x 9 and for some reason nothing I do works. Basically, when I run the game and the main character collides with an enemy, the red bar for his health just travels towards the …

I swear I used to know how to do this ... so I have this array: BYTE bcdData[6]; and a function that returns it: [code] BYTE * BCD::GetBcdData() { return bcdData; } [/code] and I have this other array in another class: BYTE tpIdByte[2]; And what I am trying to …
