how do i stop the loop?

[Rhemah]

what i really wanted to happen is have the glow value turn from 0.0 to 1.0 to 0.0 then stop.

float FADE_PERIOD = 6.0;
float TIMER_PERIOD = 0.25;

float MIN_GLOW = 0.0;
float MAX_GLOW = 1.0;

float glowAtTime(float t)
{
   float midPoint = 0.5*(MAX_GLOW+MIN_GLOW);
   float amplitude = 0.5*(MAX_GLOW-MIN_GLOW);

   return midPoint+amplitude*llSin(TWO_PI*t/FADE_PERIOD);
}

default
{
   state_entry()
   {
      llSetTimerEvent(TIMER_PERIOD);
   }

   timer()
   {
      float glow = glowAtTime(llGetTime());
      llSetPrimitiveParams([ PRIM_GLOW, ALL_SIDES, glow ]);
   }
}

and can someone teach me what does ++ do or * do im a bit confuse

++ means increment by one, -- means decrement by one, * means multiply.

And then you'll want a test in the timer event to llSetTimerEvent(0.0) if (glow >= 1.0), so that the timer doesn't keep chugging away and trying to increase glow beyond its upper limit.

is it like this? but it doesnt work:matte-motes-crying:

timer()   {        float glow = glowAtTime(llGetTime());        llSetPrimitiveParams([ PRIM_GLOW, ALL_SIDES, glow ]);        if (glow >= 1.0){llSetTimerEvent(0.0);}   }

here is a basic snippet you can play with to get it how ya like..?

SLPPF has no delay, and you stop before 1.0 and 0.0 so the compiler wont go out of bounds.

 

integer k;
float x;
integer tog = 1;
float gap = 0.1;
integer flag;
default
{
    state_entry()
    {    
    }
    touch_start(integer total_number)
    {  llSetTimerEvent(gap);
    }
    timer()
    {    x +=  0.05 * tog;
         llSetLinkPrimitiveParamsFast(LINK_THIS,[PRIM_GLOW, ALL_SIDES,x]);
          if(x >= 0.95)
         { tog = -tog;
           flag = 1;
         }
         if(x <= 0.05 && flag == 1)
         {  x = 0.0;
              tog = 1;
              flag = 0;
              llSetLinkPrimitiveParamsFast(LINK_THIS,[PRIM_GLOW, ALL_SIDES,x]);
              llSetTimerEvent(0);
           
         }
    }
        
}

thanks xiija, i'll play with this one and hope i can do something i want with my project :matte-motes-big-grin-wink:
