I'm trying to achieve a effect in motion and I'm having some problems. What I need is to make a bunch of circles falling from the air and bouncing on top of my 2D layer and then when the animation is finished the top of the layer would be clear of circles.
I've already tried to achieve this using a rain particle, changing the source file to the circle and then assigning a edge colision to the rectangle where they will be bouncing.
The rectangle is in the midle of the screen and it's width is about 20% of the 1280px composition. What I mean is that I need the particles to bounce in the rectangle and jump off it falling then into the "void".
Another problem I've found is that the heavy rain effects, for example, has it's particles arranged in 3D space (some in front of the others with different sizes). I'd like them to be all the same size, arranged in 2D space.
