collision issue

[XxWalKaxX]

this is basically the same code that clamps the poo to the window but instead of clamping im attempting to make the poo treat the "face" as a wall and bounce off, the code works fine by its self, but when it running with code to clamp poo the screen, the poo simple goes crazy and shoots off the screen and breaks the program

Code: Select all

for(int index = 0; index < nPoo; index++)
		{
			
			if(poo[ index ] .x - 20 == faceX)
			{ 
				poo[ index ] .x = faceX + 20;
				poo[ index ] .vx = -poo[ index ] .vx;
			}
			else if( poo[ index ] .x - 40 == faceX )
			{
				poo[ index ] .x = faceX + 40;
				poo[ index ] .vx = -poo[ index ] .vx;
			}
			if(poo[ index ] .y + 20 == faceY)
			{
				poo[ index ] .y = faceY - 20;
				poo[ index ] .vy = -poo[ index ] .vy;
			}
			else if( poo[ index ] .y + 40 == faceY)
			{
				poo[ index ] .y = faceY - 49;
				poo[ index ] .vy = -poo[ index ] .vy;
			}
			
			
		}
	}

Could you post your solution? I think I have an idea on what's going on since i ran into this problem myself, but I'd rather see the problem for myself so i could point you in the right direction rather than give you some wrong pointers.

ok well due to my impatience i have deleted the collision detection code, im gonna start fresh with it although i believe i may have determined the problem i could very well be wrong bc i am a complete newbie but i think the problem is im using poo[index] in 2 different fuctions and there both for collision detection---one for walls----and one for my "shield" and both are in for() statements and both are saying for(int index = 0; index < nPoo; index++)
