View Full Version : Can particles be emitted at fixed rate?

Hey all! I'm trying to shoot bullet shells out of machine guns for a movie. I'm using a particle emitter with FX Linker.

Everything's working perfectly, but I want my particle emitter to shoot out about 8.2 bullets per second, or roughly .34 bullets per frame. I can enter these settings in the particle emitter, but it only seems to shoot them out an irregular intervals. I'd like it to be a machine-steady rate, because - hey - it's a machine gun.

Anybody know how to do this?

I guess everyone's too busy speculating about Core. Nobody cares about poor little me. Sniff.

I think the "Key Effect" tab in the emitter properties panel will work for that. In Kurv studio's Particles tutorials Tim Dunn goes over this tab quickly but I think that may be the one you need. That or "Generate by Frame" rather than by Second, in the "Generate by" tab.

there is a scene in the content folder that has a machine gun setup...
can't think of where it is in the content folder.....hmmmm

Yep, your options are pretty much limited to 1. emitting one particle every frame (otherwise it'll emit randomly like you've found), 2. emitting one per keyframe event (requiring you to make a key for every shot) or 3. making an emits-per-frame envelope that spikes up to one whenever you want a particle.

I once came up with the idea of making an LScript channel modifier to ease regular/gun-like particle emission envelopes, but never followed through. :thumbsdow

Thanks guys! Setting "Generate by" to Frame and using Key Effect spat out the Birth Rate number of particles whenever the emitter has a keyframe. Perfect for what I need.

Much obliged!
