What do you need help with? V. 3.0

[robmaister12]

[QUOTE=Map in a box;31043553]I thought about that, but that would mean a new object for every particle. I didn't know how I would do physics, and render, thats 4 for loops for every particle.[/QUOTE]

you would only need 2 for loops, one to step the physics world, then another to render everything in it's current state... unless I'm doing my math wrong or something

[QUOTE=Chris220;31043870]Ah, that worked, thanks!
So, since glEnableClientState() is deprecated (as is glVertexPointer and so on), I assume the next step is to get it running on shaders instead of OpenGL's own matrix manipulation; then using glVertexAttribPointer() and so on.
Thanks again :)[/QUOTE]

once you start using shaders and your own matrices, you'll have fully forward-compatible OpenGL code (assuming you update all your code)

I'm just writing a properly error-checked shader compiler/linker class to make it all a lot easier to load a vertex and fragment shader from a couple of files, then link them together and so on.
After that, it's time to wrestle with matrices; something I'm not very good at :v:

I've got a serious problem with exporting my projects to runnable .jar files. No matter how much time I spend making sure the manifest and classpaths are correct, I always get an error like this:

Manifest:

Manifest-Version: 1.0
Rsrc-Class-Path: ./ lwjgl.jar slick.jar
Class-Path: .

The contents of my .jar:

Please help! I'm so close to releasing my first complete program I can almost taste the victory. :v:

I think you're running it wrong. On Linux at least, you need to run java -jar jarfile.jar

My classpath must be set up wrong. Any idea how to fix it?

[editline]11th July 2011[/editline]

Son of a bitch, I can make it work if I add this every time I run it on the command line:

java -Djava.library.path=C:\users\nige\workspace\defendo\lib -jar defendo.jar

But it still won't work by double-clicking on the .jar. How can I fix this?

I already know how to do that. The problem is that the exe I'm launching isn't the one that's running the game.

[Woodcutter11]

How would i prompt the user before closing my sfml window?

I've tried this:

[cpp]
#include <windows.h>

// ...

if (ev.Type == Event::Closed)
{
// Close the window
HRESULT result = MessageBoxW(NULL, L"Are you sure you want to quit?", L"AAP", MB_ICONQUESTION | MB_YESNO); // BUT WAIT!

if (result = IDYES)
window.Close(); // Now close it
else
window.Show(true);
}

[/cpp]

Ain't working.

Use the thing I forgot the name of to convert your jar to an exe, if I remember ill tell you. Also eclipse has a rightclick-export function.

Here is a puzzle for you guys:

If this->velocity.getX() and this->velocity.getY() return 0(zero) how can the new position of the sprite be set to[-2147483648,-2147483648] ?

I have a feeling I have a virus that makes my game do sh*t so I get frustrated. This is just ridiculous.

void Sprite::move()
{
     if (this->movement_type==MOVE_AUTO)
     {
          this->setX(this->getX() + (this->velocity.getX())*g_engine->game_speed*((double)64/g_engine->getFrameRate_real()));
          this->setY(this->getY() + (this->velocity.getY())*g_engine->game_speed*((double)64/g_engine->getFrameRate_real()));
     }
     
}

If I remove g_engine->game_speed*((double)64/g_engine->getFrameRate_real()) I get right result, but isn't 0*some number=0 ???

You either have an overflow, or more likely, an uninitialised variable somewhere. Check everything in that equation and make sure it has a proper value.

So, I wrote my shader compiler class, made some basic shaders. Both are getting this error:

Failed to compile shader: GL_VERTEX_SHADER
Compile log:
(0) : error C0000: syntax error, unexpected $end at token "<EOF>"
(0) : error C0501: type name expected at token "<null atom>"

No matter what I put in the shader... I'm really, really confused. Any ideas?

[AntonioR]

DIVISION BY ZERO !!!!!!!!!!!!!!!!!!

For two days I try to fix this and it was division by zero. The problem was only in the first frame of the program, g_engine->getFrameRate_real() would return 0 (some counter inside was initalised at 0) so 64/0 messed everything up.

NOTE: THIS IS NOT PART OF THE ENGINE I WROTE !

Well, this is bugging me. Used to, in like VS08, intellisense worked. Now when I try to include a library like glua or sfml, "NO ADDITIONAL INFORMATION AVAILABLE(just to make u mad trolol)" makes me mad :( I'm trying to lrn2c++

Based on what I found out in the past 10 seconds,
If the result is yes, just break out of the while loop, or (running=false in the examples) else just dont do anything

im making a console class in my XNA gaem but I cant get the text to draw D:
Just wondering if anyone else can see the problem.

-FIXED- Damn < and > confused

The console area displays fine (A white box/area) which is the render target.
But the text which should display doesnt.
I have tried changing the positioning, the font file, the colours...

Your LoadContent method is [B]LoadCotent[/B]. When you load your model you are writing [B]models\gun[/B], it has to be [B]models\\gun[/B], or [B]models/gun[/B].

I don't know what your problem is though, so i was just checking for general errors.

Im looking for a book to learn openGL, I wish it to start at the basics (window creation & displaying stuff on screen) and then go up to VBO, shaders and all the more advanced stuff.
My computers currently only support openGL up to 2.0 therefore I have no need for a brand new book.
I was however hoping that they would teach you pure openGL without the use of any 3rd party libraries i.e GLUT.
I was wondering if maybe the 3rd edition of the openGL superbible would do as you can get it pretty cheap on amazon.
