Using particls to simulate automatic gunfire Cycles The situation is i have a few gun models that i will use in a scene where there are a lot of them and they all need to be able to fire bullets easily without me animating each bullet as these are automatic weapons.
So i have a gun and i made a simple bullet that i want to use as a particle system for automatic gunfire.

So i have this bullet model right inside the bore of the gun and i parented the bullet mesh to the gun. I then added a particle system to the bullet that used the bullet model as the particle in the render tab. A couple problems arose such as the particles not appearing, they have far too much drop due to gravity especially in the case of a rocket launcher that needs to go slowly but not drop. and i also don't understand how to turn them on and off such as in a burst fire situation so it fires then stops then starts firing again.
Here is a very simple test that shows how you could defy gravity and animate particles to &quot;gunfire&quot; bullets:

this setup  could work like this:
