Im trying to make a new weapon projectile for a modding project in Halo 2, does anyone know how to do the following: 1. Make a contrail of fire (a trail of fire where the weapon has been fired). 2. When I throw a grenade, with each explosion I want it to throw out like 3 more grenades, and when they explode I want them to throw out 3 more and so on. 3. Make beam rifle shots limitlessly rebound of walls. 4. Make an air strike feature where I shoot the rocket launcher and like loads of rockets come hurtling down to where I targeted. 5. Shader swaps. Any help will be greatly appreciated. Thanks all.
