Hi,

I noticed a huge "bug" in my Game.
The left and right movement are not equal in speed:

going stair up
1  
2  
activeProt.x += 0.5f * delta;
activeProt.y -= 0.5f * delta;


going stair down
1  
2  
activeProt.x -= 0.5f * delta;
activeProt.y += 0.5f * delta;


When I go down, the character won't go through the starting point. It goes more to the right.

I already noticed, that going straight left and right are at a different speed. Right appears do be faster. Why??

I set the FPSTarget to 60.
By the way, I am using Slick2D.

Thanks for your help.

edit:

the x and y coords are integers... is that the point??

yes indeed Sad

But I already fixed it, now I come up with a lot of other errrors which depended on that. First I used the AWT Rectangle, now the Slick Rectangle, but the intersect Method appears to be buggy, so I overrid it with the intersect method from the AWT Rectangle.

All coding knowledge will be useless at peak oil.
