Variaton on a poofer, need a hint or three

I have almost no experience with particle effects and none with poofers, but want to trying one to see if it will help create a particular visual effect. What I need to figure out it how to make one that only creates a single image of a texture and to be able to control its speed, direction and life so that is goes down at a fairly steep angle towad the ground and then dies. Any help would be appreciated

What do you mean by " control" ??

Velocity and lifetime can be set to a certain extent.

I would suggest going to the particle Laboratory. Look at all of the stations there. You will find one or two showing you exactly what to do. Might try looking specifically att he "drip" display.

This can be a little tricky. I've tried to achieve similar affects, where I just want one copy of the particle, but it was hard to get it to work reliably. Either I would tune it too far in one direction and sometimes not get any particles or I would tune it too far in the other direction and get more than one particle. In any case I think you first need to look at these parameters:

PSYS_SRC_BURST_PART_COUNT, PSYS_SRC_BURST_RATE and PSYS_SRC_MAX_AGE

The count should obviously be 1. Then set a rate that is a little bigger than the age. Say 10.0 for the rate and 8.0 for the AGE. This means that in the 8 seconds that the particle effect is active, the effect should only fire once, since it fires every 10 seconds.

I'm not positive this will work properly under all conditions.

Another possibility is to rez a temporary invisible object, send it where you want the particles to go, and use it as the particle target. Or, if you can get away with it and you don't have to rez them extremely often, just use the rezzed object itself for the effect (then you can get land collision events and everything).

Thanks for the info all and expecially Keiki and Hewee. I will give you suggestions a try.
