This demo shows an updated version of my Sliding Tile Collision Code.
The actual code is quite small and should be quite easy to plug into anyones project should they need it.
Tile collisions form the basis for a lot of games, usually 2d platformers, where the tiles define the collision geometry for the game, which do not get drawn and the actual game graphics are drawn on top of the collision geometry.
This is the method i used in my 'Mayhem's Adventure In Monsterland' Demo for example.
The player movement in the demo uses fixed point math to add velocity to the players position at integer values.
This ensures perfect collisions.
Smoother movement for the player can be achieved using Floats but this introduces a visual error of 1 pixel when resolving collisions.
Space = Reset Tiles
Cursor Keys = Move Player
(F1 , F2) (F3 , F4) = Alter The Tile Size ( The Tiles Can Be Rectangles As Well As Squares )

Run Demo.exe for the demo
