Ok, that seems to be the easiest in the long run. Just a quick question
collisionBoxArray.add (new CollisionControl(x,y,mapX,mapY));
where does the mapX and mapY values come from?
It’s the current location of the exact top left corner of the entire map in relation to the screen/camera (not just the tiles you’re rendering).
OK, i have the players collision box set up with a bit of modifying because of the camera code, and i can see it being drawn round the characters feet. I am having trouble working out how to find the mapX and mapY values though.
Ok, i have the collisions working from every direction. Stopping the player in the correct place and moving it backwards to stop it getting stuck. I just need help on how to get the maps coordinates, not the screens, at the moment the collisions are being drawn in the center of the screen. The tile x/y values are correct when i check the array
Ok, this is what i have so far for the map class

The code for updating the collisions when the player moves
Now whats happening is the collision boxes are being drawn in the right place, but when the player moves they’re not updating correctly, and if the player steps on the box its being ignored
This is what i mean
