Hello,

I am a beginner in game programming in sdl.
I am following aaron cox's tutorial's at http://www.aaroncox.net/tutorials/

He has given an sdlGameEngine and using it he has explained how to deal with game basics.
Everything has worked fine but collision detection is not working.

I have included all the source code of the msvc project.
The controls to move bigbug are the arrow keys and to move the smallbug are asdw .
The bugs should stop while colliding with screen and rock.

Thanks in advance.
