I'm firing lasers against a wall, which is a simple cube. When the laser hits the wall, I'm creating an explosion with particles. How can I know the Rotation of the generated 2D particles for making them facing the side of the cube that has been hit ?
Is it something as simple as a checkbox that I didn't find? Or do I have to calculate complicated things? And if it's complicated, would it be better to generate 2 faces of particles like for those trees?

I must precise that my particle emmiter is in the onCollision of the Laser, and that there is going to be a lot fo particles...
Thanks

Edit: Sorry, I opened many tabs to search for info in the forum and I didn't pay attention to where I was posting. I was sure I was in the "General discussion", wondering why there wasn't an "Help" forum ...
