If you don't want gravity just it to zero than . Or if you are not sure what you want, watch a video of a game where you think the rocket+smoke looks awesome and carefully observe how they made it (for example: how do their smoke particles move?).

OK. I have just one question. I know it's very very dumb and newbie-only ,but to make sure: Which particle function is executed EVERY FRAME? The one set in the "effect()" instruction or the one set by "event" parameter of the particle or both? The manual says the first one ,but I wanna be sure ...

...

See manual -> effect, then the example code and you will/ should realize that the particle function used as an effect(...) parameter gets only called once for initialization, p.event (if any) every frame.

Thanx .

The manual here: http://manual.conitec.net/aent-effect.htm
(in the "parameters" sections) says: "function: Particle function; runs every frame ". That is what confused me ...

Hm I see what you mean. Usually a particle function has the following template:



When you don't want to have a fade out function you normally write p.event = NULL; but I guess the event is set to the initialization function (p_fnc here) by default (which would not make much sense then as you overwrite lifespan, vel_xyz and the like over and over). Just always use p.event then.

I see ....

Thanx a lot for clarification .....
