Hey all! So, i’ve been wondering, how can i make a bullet ricochet when it hits a wall?
For example, it hits a wall, and then bounces off to another direction.
Any help is appreciated! 
Here is a paper describing a model of ricochet. However, I’ve never implemented it myself. http://www.jstor.org/discover/10.2307/1141977?uid=3738032&uid=2&uid=4&sid=21101750558127
