I can't quite figure out why my code doesnt work BUT I have narrowed it down to the area that is triggering it.
This code from the main.cpp's SetupWorld() Function
for ( int B = 1000; B <= 2000; B++ )
{
myBlocks.ExclusionCheck ( B );
}
You can remove the for loop and manually set B to any number between 1000 and 2000 and it works just fine, put the for loop back in there and it throws an exception. I've been pouring over this for 3 days
The world is setup by creating one large square out of 10x10x10 little squares, the ExclusionCheck looks at each block individually and it's 6 surrounding blocks, if all 6 surrounding blocks are present it hide's the block it was looking at since the player can't see it and that dramatically reduces poly count in my game. If someone has a better way of doing this than mine please do say
Exception:

I hope that helps.
EDIT: I solved the problem, it was when i initialized the variable int SurroundingBlock[5], i thought that would give me array places between 0-5. but actually it only made it 0-4 so i increased the size of the array by 1 and no more problems!
Add me to your MSN!
