i hate to post this on here... cuz it is so simple... yet i can't do it... well... here it is:

i am having issues with my collision... i am using the sprite collision code... here is my code:

+ Code Snippet

   if sprite collision(1,0)>0
      x = oldx
      y = oldy
      sprite 1,x,y,1
   endif

i would like to know why this code makes my character (sprite 1) jumps to it's starting position... how do i get it so that he stops moving... but doesn't go back to it's starting position? BTW... i am using DBC

1) you should update oldx and oldy everytime you move
2) however, will you find useful to know if the collision gets triggered on a specific axis?
(eg. may be you could want to know if the collision between 2 sprites is lateral - along the x - or vertical - along the y - if you want to change direction for something or so)

3) if your problem is just about stop moving, and not about restoring old coordinates, you should try something like

+ Code Snippet

(direction assignment code, probably based on cursor keys, here)

if (collision code condition here)
   xdirection = 0
   ydirection = 0
endif
x = xdirection * xspeed
y = ydirection * yspeed

sprite 1, x, y, 1
