Go for it, couldn't hurt.

[MagmaMcFry]

Remember that platformer I made? Here's the source. The OpenGL calls are slightly scrambled (this was a bottom-up project), but should be easy to read.

Thanks be te ye good sire.

Thanks be te ye good sire.

By the way, that's an Eclipse project there, you can just go ahead and import it, should run fine.

[Max White]

Do you mean to imply there is such a thing as a non-Eclipse java project?
What else would one program in, Netbeans? Hohohohoho.

For all I know you could have used Emacs. C-x M-c M-butterfly.

Or vim and maven. Why nobody likes maven?

You. I like you.

Or notepad and javac...

Back when I was in college, we used Java nearly exclusively. One of the professors used the above for all of his work. It wouldn't be a problem if he were good at it, but he wasn't.

Warglebargleargh. Trying to install proprietary NVIDIA drivers onto my Linux Mint partition for some advanced OpenGL features. Broke my computer while doing so, subsequently unbroke it. The drivers have yet to be installed.

Suggestions for lowering CPU usage in SDL, other than "Learn OpenGL"
GO!

Step one, profile.

Edit: There's this computer-related theory that states 5% of your code takes up 95% of your runtime.
Also that famous saying that premature optimization isn't worth it.
Also you don't know what is taking up your CPU cycles. Maybe you wrote some inefficient code, or you're doing something stupid like access a vector with at() 160000 times a frame, thirty times a second. *cough cough*

[MagmaMcFry]

Step zero, limit your framerate.

Code: [Select]

// Initialize lastSyncTime to SDL_GetTicks().
// Then call this function every tick, with the framerate you want your game to run at.

int sync(int fps) {
unsigned int waitTime = 1000.0f/fps;
unsigned int currentTime = SDL_GetTicks();
while (currentTime - lastSyncTime < waitTime) {
SDL_Delay(1);
currentTime = SDL_GetTicks();
}
unsigned int waitedTime = currentTime - lastSyncTime;
lastSyncTime = currentTime;
return waitedTime;
}

That ounts as something stupid xD

Granted, won't find it from profiling, as easily.

Step zero, limit your framerate.

Already done,


going to poke around at some optimizations right now, even though its a bit premature,
I has hoping there might have been some sort of super secret to optimization secrets I didn't know about, but I guess not.

thanks anyways
