Pretty much I'm trying to make falling leaves spin while staying flat on the screen, and I made a function draw_leafs that successfuly draw the leafs but when I use rotate in the draw_leafs function to set each of them in a different starting position, it make some of them rotate out of the screen or flip in a way that we see their back, but I always want the leafs to have a front view and only spin on themselves along the plan (along the y axis).

I'm not at the animation step yet, I only want to draw the first leafs in a way that they have each a different rotation, while all facing the camera.

The way I set them a random rotation degree angle is this way:

r = Math.random() * 360 * Math.PI / 180;

I hope I made myself clear enough.
