I get a lot of Scratchers saying there collision detection scripts work fine for there platform games, but that it all goes wrong when they try to write a scrolling game, well here is a little project made as simple as possible to show how I have been doing it. Simply put, we do things just the same as you would for a non-scrolling game where the player is 'actually' moved around and collisions checked for and fixed, and only then do we move both the player AND the level (by the same amount) such that the player returns to the centre of the screen and the level scrolls. Let me know if I need to explain this any more simply? But look inside first and try to examine the scripts... there aren't many of them!
