Particle Rainbow Effect

[DeepusMaximus]

Hi Everyone,

Im pretty new at SL and I just got around to designing some glowrings, which rotate between 4 colours every 1 second. Now I have a streak effect (from my other greenglow rings) which I would like to use but also incorporate this code I found online which should allow for the particles to also rotate between colours.

I managed to get both my code and the code I found online to save nicely and the touch function works great, the particles are released upon touch...but the colours arent changing at all.

Here is what I have so far:

float red;
float green;
float blue;

float loop = 0.;
integer stage = 0;

integer doStuff = FALSE;

particleStuff()
{
         llParticleSystem( [ 
             PSYS_SRC_TEXTURE, "streak3", 
             PSYS_PART_START_SCALE, < 0.2, 0.3, 0 >,  PSYS_PART_END_SCALE, < .01, .01, 0 >, 
             PSYS_PART_START_COLOR, <0.180, 0.800, 0.251>,    PSYS_PART_END_COLOR, <0.004, 0.000, 0.939>, 
             PSYS_PART_START_ALPHA, 0.8,            PSYS_PART_END_ALPHA, 0.4,     
              
             PSYS_SRC_BURST_PART_COUNT, 1, 
             PSYS_SRC_BURST_RATE, 0.000001,
             PSYS_PART_MAX_AGE, 1,
             PSYS_SRC_MAX_AGE, 0.0 , 
 
             PSYS_SRC_PATTERN,   PSYS_SRC_PATTERN_EXPLODE, // DROP, EXPLODE, ANGLE, ANGLE_CONE,
             PSYS_SRC_ANGLE_BEGIN, 0.2,   PSYS_SRC_ANGLE_END, 0.0,  
             PSYS_SRC_BURST_RADIUS, 0.001,
             PSYS_SRC_OMEGA, < 0.00, 0.00, 0.00 >, 
             
             PSYS_SRC_BURST_SPEED_MIN, 0.0025, PSYS_SRC_BURST_SPEED_MAX, .15, 
             PSYS_SRC_ACCEL, < 0.0, 0.0, -0.001 >,  
          // PSYS_SRC_TARGET_KEY, llGetKey(),             
             PSYS_PART_FLAGS, ( 0 // | PSYS_PART_EMISSIVE_MASK        
                                  // | PSYS_PART_BOUNCE_MASK

                                  // | PSYS_PART_TARGET_POS_MASK     
                                  // | PSYS_PART_TARGET_LINEAR_MASK    
             ) ] );
 }
 
 colorChange()
{
    if ( stage == 0)
    {
        red = 1.; green = loop; blue = 0.;
    }
    else if ( stage == 1)
    {
        red = 1. - loop; green = 1.; blue = 0.;
    }
    else if ( stage == 2)
    {
        red = 0.; green = 1.; blue = loop;
    }
    else if ( stage == 3)
    {
        red = 0.; green = 1. - loop; blue = 1.;
    }
    else if ( stage == 4)
    {
        red = loop; green = 0.; blue = 1.;
    }
    else if ( stage == 5)
    {
        red = 1.; green = 0.; blue = 1. - loop;
    }
    particleStuff();
}

default
{
    state_entry()
    {
        llParticleSystem([]);
    }

    touch_start(integer total_number)
    {
        doStuff = !doStuff;
        if ( doStuff)
            llSetTimerEvent( .5);
        else
        {
            llParticleSystem([]);
            llSetTimerEvent( .0);
        }
    }

    timer()
    {
        loop += .05;
        if ( loop > 1.01)
        {
            loop = 0.;
            stage++;
            if ( stage > 5)
                stage = 0;
        }
        colorChange();
    }
}

 

Any thoughts? Did I overlook anything?

Much appreciated!

something mebbe like changing ...

 PSYS_PART_START_COLOR, <0.180, 0.800, 0.251>,    PSYS_PART_END_COLOR, <0.004, 0.000, 0.939>, 

into

 PSYS_PART_START_COLOR, <red, green, blue>,    PSYS_PART_END_COLOR, <red, green, blue>,

You went to the trouble of defining the variables red, green, and blue as global floats, and you built them into your ColorChange function, but you never incorporated them into the ParticleStuff function, so nothing is going to change.

ahhhhh....i see...makes sense! ok cool, ill try it out in a bit! fingers crossed

[DeepusMaximus]

Ok the particles seem to be working now great! but unfortunately the ring themselves stopped rotating colours. This is the script Id been using:

    llSetTextureAnim (ANIM_ON | LOOP, ALL_SIDES, 2, 2, 0, 0, 1.0);

Its fine unless I activate the particles.

I tried incorporating this into the code I pasted up originally, it saves fine, and start off as normal. But stops once the particles are activated by touch.

So my code looks like this as of now:

float red;
float green;
float blue;

float loop = 0.;
integer stage = 0;

integer doStuff = FALSE;

particleStuff()
{
         llParticleSystem( [ 
             PSYS_SRC_TEXTURE, "streak3", 
             PSYS_PART_START_SCALE, < 0.2, 0.3, 0 >,  PSYS_PART_END_SCALE, < .01, .01, 0 >, 
             PSYS_PART_START_COLOR, <red, green, blue>,    PSYS_PART_END_COLOR, <red, green, blue>, 
             PSYS_PART_START_ALPHA, 1.8,            PSYS_PART_END_ALPHA, 0.4,     
              
             PSYS_SRC_BURST_PART_COUNT, 1, 
             PSYS_SRC_BURST_RATE, 0.000001,
             PSYS_PART_MAX_AGE, 1,
             PSYS_SRC_MAX_AGE, 0.0 , 
 
             PSYS_SRC_PATTERN,   PSYS_SRC_PATTERN_EXPLODE, // DROP, EXPLODE, ANGLE, ANGLE_CONE,

             PSYS_SRC_BURST_RADIUS, 0.001,
             PSYS_SRC_OMEGA, < 0.00, 0.00, 0.00 >,

wrong code

[Xiija]

erm, congratz! .. You have found a new bug!

apparently, turning on particles turns off texture anim ?

mebbe someone else can check it

 

as a work around, just put the particles in another prim and send it a msg?

[Narthex]

It looks like you're updating the texture animation faster than it can play frames. Unless you need to switch the state of the texture animation, it shouldn't be in any of the timer or color change scripts.
