Mini putt logic?

Hello,

I am trying to figure out the mini putt logic… I understand that you give an angle and force then hit the ball. Now, once it hits a border, is it : the straight angle of the border minus ou plus (depending on the side) the angle of the ball that gives us the bounce angle? Any tips/formulas welcome :smiley:

i really need help bad!!! :slight_smile:
how to get the bounce angle of the balls when it hits another object and render its path?? any ideas??

I think it leaves the wall at the opposite angle it hits…
