Hi,

i have a small suggestion for the particle-generator.
The first idea is a "attack" and "delay" value, to set how much
particles
begin or end to flow (the second were to set the speed of particles!)
The sencond idea is to do a list for set more then one start/end value
for particles.

Like this:

particles_time {
     1,50 ,5,1.0 ,10,0        //means:  start at frame 1 end at frame 50

                                  //Particles needs 5 frames at start to
go to 100 % of particle-"rate" and 10 frames at end to go to

0%
     80,150 ,1,0.5 ,1 ,0.5   //Start at frame 80 and end at frame 150
    //Go to 100 % of "rate" after one frame and to 50 % at the last
frame
     200,250,49,1.0,1,0.0   //Start at frame 200 and go to frame 250
     //Go from 50 % (see last line!! 0.5) to 100 % at frame 249 (49
long) then stop at the last frame (0 %)
}

To simulate a sprinkler you must use something like this (for a 25 FPS
animation):
particles_time {
     1,20,5,1,1,0  //go from frame 1 to 5 at 100 % and go to 0 % at last
frame
   //pause of 10 frames
     30,40,5,1,1,0 //Go from frame 30 to 35 at 100 % and go to 0 % at
last frame
   //pause of 10 frames
     50,60,5,1,1,0 //Go from frame 60 to 65 at 100 % and go to 0 % at
last frame
 //and so on..
 //also possible (and easier) with a loop and variables
}

Have someone understand me??  ;-)
