Imagine that you’re running at 10 MPH. While you’re running, you throw a ball at 5 MPH. Now, imagine the laws of physics are screwed up and the ball, instead of adding your running velocity to its own, only moves at its 5 MPH. Imagine the look on your face when you try to figure out how the heck you just did that. Imagine the towns’ people accusing you of being a witch and burning you at the stake. Gruesome.
This is (sorta) what happened to me. I instantiated particles, but they didn’t pick up the instantiators’ velocity. Well, here’s a handy script I found, and now I am sharing it to help get your game up to speed (Ugh. I rather just be burned at the stake than to hear another corny pun).
