Doom3world

I'm attempting to add a particle emitter to a moving platform, but I'm having trouble getting the desired effect. I'd like it to pop out particles only when I trigger the emitter (not constantly like a chimney).

When I use a func_emitter:
- the particle orientation/position get locked to the moving platform. This looks awkward.
- if I re-trigger it before the end of the particle duration, the previous batch of particles instantly disappear.

When I use a func_fx:
- it has the same problem of the particles disappear if I re-trigger it before within the particle duration time.

When I use a func_smoke:
- The particles are not affected by the moving platform or orientation - that's great.
- It lets me trigger it as often/quickly as I'd like - that's also great.
- The problem is that it behaves like a smokestack - it constantly spews out particles like a chimney. A workaround is to trigger it and then re-trigger it again one frame later, but that screws up the particle timing.

I haven't been able to find any other particle emitter types. Any suggestions?

Here's an idea I did once: when you do the trigger have the script spawn a func_emmiter at the origin of the mover with the preset attributes you want, then have it removed when it's done. I did stuff like this years ago: viewtopic.php?t=12352

Cool, that should do the trick. Thanks!

Happy's idea is a good one, but use a func_explosion instead as they self remove, just dont give it any damage def or sound. All dependant on what you want that is.

Ohh, good idea! I would of had it spawn a func_damage & speaker to do those, didn't think of a func_explosion that would solve all those problems!

Good tip - I tried it out and it fits the bill nicely. Thanks!
