Fun with timers!

Basically, I have a poofer that I want to incorporate chat control of the colors, since it matches something tintable.

I can't get the vector color changes to take. Any ideas?

I appreciate any help you can give!

key owner;
integer h_listen;

//ginormous and irrelevant particle script stuff

default
{

state_entry ()
{
owner = llGetOwner();
h_listen = llListen(3,"",owner,"";
llSetTimerEvent(0.0);
llParticleSystem ([]);
}

listen(integer channel, string name, key id, string msg)
{
if(channel==3 && llToLower(msg)=="trigger"
{
llSetTimerEvent(1.0);
}else
if(channel==3 && llToLower(msg)=="black"
{
Start_Colour = < 0.0, 0.0, 0.0 >;
End_Colour = < 0.0, 0.0, 0.0 >;
llOwnerSay("Seed color set to black.";
}
}

timer()
{
myparticle ();
llSetTimerEvent(0.0);

}



}

After you change the start and end color you have to restart the particles.
I've changed a little pooferscript I had in inventory to something to show this.

integer t;
vector color;

integer rate = 4;
float base = 0.8;
integer index = 0;
integer iters = 0;
integer gPartCount = 5;
float gBurstRate = .2;


poof()
{
    llSetAlpha(0.0, ALL_SIDES);
    llParticleSystem([PSYS_PART_FLAGS, 
        PSYS_PART_INTERP_SCALE_MASK|PSYS_PART_EMISSIVE_MASK|PSYS_PART_INTERP_COLOR_MASK|
        PSYS_PART_FOLLOW_SRC_MASK|PSYS_PART_FOLLOW_VELOCITY_MASK, 
        PSYS_SRC_PATTERN, PSYS_SRC_PATTERN_ANGLE_CONE,
        PSYS_SRC_ANGLE_BEGIN, PI/3,
        PSYS_SRC_ANGLE_END, PI*2/3,
        PSYS_PART_START_SCALE, < base, base, base>,
        PSYS_PART_END_SCALE, < base, base, base>,
        PSYS_SRC_MAX_AGE, 0.,
        PSYS_PART_MAX_AGE, 4.,
        PSYS_SRC_BURST_PART_COUNT, gPartCount,
        PSYS_SRC_BURST_RATE, gBurstRate,
   
        PSYS_SRC_ACCEL, < 0, 0, 0.2>,
        PSYS_SRC_BURST_SPEED_MIN, 0.1,
        PSYS_SRC_BURST_SPEED_MAX, 0.2,
        PSYS_PART_START_ALPHA, 1.0,
        PSYS_PART_END_ALPHA, 1.0,
        PSYS_PART_START_COLOR, color,
        PSYS_PART_END_COLOR, color
    ]);
}

poof_off()
{
    llSetAlpha(1.0, ALL_SIDES);
    llParticleSystem([]);
}
            
default
{
    state_entry()
    {
        poof_off();   
    }
    
    touch_start(integer n)
    {
        ++t;
        float c = (float)t/5;
        color = < c,c,c>;
        poof();
        if (t > 5) {
            poof_off();
            t=0;
        }
    }
}
CODE


Put it in a prim. Then every time you touch the prim, the particles become a little lighter.
