good template, really works good.
Thanks!
I had that same issue and it drove me crazy.
That was when I figured out the flipper was traveling too fast for collisions to be recognized. To fast for the human eye to see.
I added in the Angular Velocity to the events to slow the flippers down and that eliminated the ball seeming to go through the flipper and the ball jumping off the point of the flipper.
I also set all objects that create an angle that interferes with flipper collisions to have a small amount of Elasticity so ball is not coming in a straight line and that helps with collisions.
Physics is a very strange world on a computer because of frame rates and how objects interact if they are close to each other even when not touching.
Glad you liked the Demo and if you bookmark it I will be updating with more tricks as I go along.
Oh and Merry Christmas and Happy Holidays!
