help with particles

hey. im new to SL and the forums.
im trying to make a script that will allow the particles to change colour on a timer with llSetColor. but im not sure how to incorporate it or even if its possible. any help wold be apreciated, thanks

Welcome to the fora and SL.

llSetColor isn't the right call. If you're ok with particles already you'll see there is a particle colour flag (two actually).

Your timer() event should call the particle system afresh each time, with new values for the PSYS_PART_START_COLOR item. You can also make the particles change colour over their lifetime by setting the PSYS_PART_INTERP_COLOR_MASK flag which will let you bring the PSYS_PART_END_COLOR value into use.

default {
state_entry() {
llSetTimerEvent(1.0); // generate a timer event every 1 second
}

timer() {
llSetColor(<llFrand(1.0),llFrand(1.0),llFrand(1.0)>,ALL_SIDES); // set a random color
}
}

Hi Angus I found it here, with more examples and coments. Hope it helps.

...this won't help him with particles. The script you provided changes the color of the prim.

I have a particle script I wrote for a ship of mine that allows it to change colors off a menu in the root.

Basically I just have the script set to receive link messages and when it receives the name of pre-set colors, it sets the BEGIN and END colors in the particle parameters to set values and restarts the particles.


Like for pink it has BEGIN <255,0,0> and END <255,255,255> so that it transitions from red to white and results in it being pink through most of the particle (this is just with the default particle of course...no texture)

You need to use the llParticleSystem() function to change particle colors, not llSetColor()....

If you want a combination of multiple colors you're better off using a few prims each with their own particles defined with different colors. Using a timer to change particle colors is 'icky'. (using short timer intervals to re-define the particle display can contribute to lag)
