hi guys coudl you guys help me when i run the program i get a assertion failed message could you help me please? here is the source code for main.cpp

I dont suppose you have the game running in window mode? Or you can remote debug? Because then you could just step through and find out where it hits the offending ASSERT

Thanks for Replying the assertion says

Debug assertion failed

Program ...stdio/myprojects/opengl framework/debug/opengl
framework.exe
file dbgheap.c
line: 1017

expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

any Ideas?

Thanks

Please Reply

Yes, that assert is VERY annoying. I''ve had it numerous times. As i recal it is caused by attempting to use either a NULL pointer or a an undefined pointer. I think both cases fail the debug assert found in the VC++ code. If you were to compile in Release you wouldn''t get the error, but your program would crash. TO fix this you should set the debugger to go line by line and keep hitting next until the error pops up, then go see what pointer is screwed and figure out how to fix it.

He who said money was the root of all evil knew little of the nature of money and less about the nature of man.
