Try this:

+ Sprite: On collision between Sprite and Box

-> Sprite: Set angle to 180-Sprite.Angle+2*Box.Angle

Just make sure to set the angle of the walls (Box) accordingly. The Left wall should have a angle of 0, Top wall 90,... etc.

Hi R0J0hound , thank you for this valuable information.

I Just wonder what if walls didn't place like a square box. What if collision object was an ellipse ? Than how can I give angle to it ?

R0J0hound thanks, it works perfectly. <img src="smileys/smiley32.gif" border="0" align="middle" />

You could also try using the Ball movement instead, which has actions to bounce off any angle surface.

maybe this can help-

It uses the custom behavior and can work for any surface.
