Collision progress

I have made some progress with the collision detection.

I have got it now that the player checks to the anchor point of another sprite and can then react to the overlap of the sprites.

I tried the rectangle collisions but had to collaborate with one of the game engine developers to see if the game engine was at fault as my code was ok to him. He is currently reviewing a section of my code to see what has went wrong. I should hear back from him at some point. In the meantime, I am going to work on the logic for getting the enemies to appear on the screen.
