One of my last posts was about back face culling. This was because of my performance problem while trying to render 130 000 blocks smoothly. I also said I was going to optimize the world data a little bit before applying shaders (I didn’t know I was already using …
After getting the X-th virus on my computer (with Windows XP Professional), I decided to start using Ubuntu 11.04. I like it pretty much, although I’m still a bit irritated by the sudo-stuff.
I spent a lot of time trying to figure out how to install my C …

After spending hours trying to figure out why my mouselook function didn’t work with SDL, I finally got a solution.
The problem was that I didn’t use SDL_PumpEvents() before calling SDL_GetMouseState(). But if I do that I get the next problem: my Keyboard Events get delayed because the …
Almost done with rewriting Mineshooter to work with the Simple DirectMedia Layer Library. Still have a few problems with the mouselook, but I should be able to work out a solution very soon.
SDL is quite simple. I now have about 150 lines less than when I used the Windows …
I’m currently working on learning SDL and am also thinking about making my Mineshooter Projekt use SDL. Does anybody have experience with programming SDL-Applications and would advice against using it?

Finally worked out the World-Collision problem. The player now collides perfectly with the blocks, but there is one problem left:
If you collide with a block in front on you, “you look inside the block”. That’s because you are 0.0f long 0.0f wide and the near clipping …
