				| How could I fix this? Here is my collision detection: 
 	  | Turing: |  	  | 
if a ('d') and x1 + rad1 > x2 and y1 > y2 - rad2 and y1 < y2 + rad2 then
 x1 -= speed
 elsif a ('a') and x1 < x2 + rad2 and y1 >= y2 - rad2 and y1 < y2 + rad2 then
 x1 += speed
 end if
 if a ('w') and y1 + rad1 > y2 and x1 + rad1 > x2 and x1 < x2 + rad2 then
 y1 -= speed
 elsif a ('s') and y1 < y2 + rad2 and x1 + rad1 > x2 and x1 < x2 + rad2 then
 y1 += speed
 end if

 Here's how I draw my boxes, and I move it with a-s-w-d:
 
 	  | Turing: |  	  | 
    Draw.FillBox (x2, y2, x2 + rad2, y2 + rad2, col2)
    Draw.Box ( x2, y2, x2 + rad2, y2 + rad2, black)
    Draw.FillBox ( x1, y1, x1 + rad1, y1 + rad1, col1)
    Draw.Box ( x1, y1, x1 + rad1, y1 + rad1, black) | 
 
 Now if I'm against the other box, it sometimes sticks to it.
 eg: If I press 'd' and go right against the second box, I can't go back left with 'a', but I have to go up or down with 'w' or 's' because it gets stuck.
 EDIT: Same happens with up or down.
 
 Actually I just realized my collision sucks, I'll re-write it.

				| I think it is because you are missing a coordinate. Try: 	  | code: |  	  | if a ('d') and x1 < x2 and x1 + rad1 > x2 and y1 > y2 - rad2 and y1 < y2 + rad2 then
x1 -= speed
 elsif a ('a') and x1 < x2 + rad2 and x1 + rad1 > x2 and y1 >= y2 - rad2 and y1 < y2 + rad2 then
 x1 += speed
 end if
 if a ('w') and y1 + rad1 > y2 and y1 < y2 + rad2 and x1 + rad1 > x2 and x1 < x2 + rad2 then
 y1 -= speed
 elsif a ('s') and y1 + rad1 > y2 and y1 < y2 + rad2 and x1 + rad1 > x2 and x1 < x2 + rad2 then
 y1 += speed
 end if

				| Ah thanks so much. I'm practicing networking with Turing now that I got a crap computer from the school by moving boxes and having them collide  |
