ArrayList - having different images when moving using arrow keys

[Chrisir]

@Chrisir

when a key is pressed loop over the images and display only where the key matches the pointingDirection

make a global var pointingDirectionFromKey

if(key==UP)
pointingDirectionFromKey=0; // North

etc.

and then when display the images check if(image.pointingDirection == pointingDirectionFromKey)
