Vector bounce?

so basicaly im trying to make it so when the vector collides with a wall it bounces off. I tried to do this but it only lets me reverse the movement of the vector. please help :]

I don't know the vector movement, but I'd say to simply reverse the x and y components of the ball

how do i do that?

please help:[

Use the Clickteam Movement Controller object.

There is a "Select object" action.. choose your object.
Then go to the Vector Moment submenu and do whatever you want.

And please don't bump your topic after 30 minutes...

You need to calculate the normal angle of the wall at that point and do a vector reflection over that normal angle line. If V is the vector and N is the normal angle at the wall, the reflection is V - (V dot N) * N

i tried to fource bounce but when it hits a wall vertically it goes rigt thorught example pelase
