[font=Arial][size=2]Hi,[/size][/font]
[font=Arial][size=2]I am having a bit of a trouble working out collision with multiple objects. The point is, if a MC called “ball” collides with a wall on either left side or right side, it should stop. Same goes with top and bottom. Horizontally it is working fine, but vertically it just seems to get stuck.[/size][/font]

Could someone go through the attached file and throw some light on why this is happening.
P.S - The file uses Flash 4 syntax but is programmed using Flash MX.
K.David.

When you get your char properties from the walls, they’re not onEnterFrame, so you only take the starting ones, not the constant, up-to-date ones…Also I don’t understand why your walls have 3 frames when they could have 1…
