ImagesCollide problem

BlitzPlus Forums/BlitzPlus Programming/ImagesCollide problem

I am using ImagesCollide to check and see if a moving object collides with a tile on the screen. If I move my ship from left to right it hits the tile as expected (the right edge of the ship collides with the left edge of the tile).

However, if I move my ship from the right to the left, I don't get into my ImagesCollide test until the left side of my ship is at the left side of the tile. It *should* collide when the left side of the ship hits the right side of the tile.

I thought perhaps this was a side effect of the HandleImage setting, so I set both objects to use 0,0 for HandleImage, but that made no difference.

Anyone else had similar problems? I have seen a few posts talking about how well the pixel perfect collision works, but haven't seen it in my game.

Thanks,
