I was on the Lichcraft server (us.lichcraft.com) and noticed the Grenade Launcher. Since then, I have been trying to duplicate it, so I could use the knowledge I got from doing so, in future projects. Using a snowball, I have found I can produce the same result, minus the fact you can see the projectile, and it doesn't bounce. I figured there were two ways to solve this. 1. Create a new projectile (I figured it would be similar to creating a Custom Entity), and alter the code, to make the desired effect. 2. Create a mathematical algorithm that can do the desired effect. I figured that the second one was at use on this server, but creating a new projectile would make it much more efficient. So, basically I need help choosing the more efficient path, and how to get the desired effect. Thanks in advance!
