Physics Randomness in GameSalad

hatch

Im creating a puzzle game where you have the bounce balls using paddles around the screen at objects. trajectory and positioning are important.

However I'm noticing that when i just leave balls spawning in the one direction onto the same surface that the balls don't follow the same trajectory each time. There seems to be a slight randomness to the physics and the variation is about 1 in 3. Basically when i leave the game running every third ball goes in the direction it should.

When you are trying to build a game where the player needs a certain level of confidence built up when they position the paddle in the right location its a little disconcerting when this randomness kicks in.

Does anyone know whats happening here and how to fix it?

Thanks

Check the Collision rules on the Ball actor.

Thanks Mark. Nice. I notice there is no gravity in your experiment. The main issue for us is that we have gravity and momentum as the key conflict forces in the game. While a little randomness is good, what is noticeable is that the GS engine seems to have this randomness built into it which makes accuracy a little inpredictable.
