Using a standard touch_start particle emitter (emitting drops of blood). turning it into a candle with dripping wax, but the prob Im running into is the drip starts on rez when I need it to start when an object is sat on. any help, even if pointed in the proper direction will be greatly appreciated.

You'll need to use the 'changed' event (http://lslwiki.net/lslwiki/wakka.php?wakka=changed), specifically CHANGED_LINK, to detect when someone sits on the object. There is actually a good example on that page that explains to detect when someone sits on it. You can then start and stop your particles from that.

May be I read the wiki wrong or perhaps just didnt read it right .. does this go in the particle script that is in the child prim?

Syntax Error
05-14-2009 17:44
Adding this:
{
state_entry() {
llSitTarget(<0, 0, 0.1>, ZERO_ROTATION); // needed for llAvatarOnSitTarget to work
}

changed(integer change) { // something changed
if (change & CHANGED_LINK) { // and it was a link change
// llSleep(0.5); // llUnSit works better with this delay
key av = llAvatarOnSitTarget();
if (av) { // somebody is sitting on me
llSay(0, "Get waxed!";);
}
gives me a Syntax error with this line:

}
touch_start(integer total_number)
{

missing bracket
05-15-2009 06:54
it looks as if you are missing a bracket for an IF - harder to see in forum without indentation. I always think that the style placing first bracket on same line as finction or IF or whatever, is not helpful and , personally , would always go for first bracket on next line in column of first letter and then last bracket in same column as first - visually much clearer in my view :-)

I suppose changed( ) must register change of avatar linking and so must be in prim which is being sat on. Then can particle system change be trigggered from that changed( ) content? I imagine so but not sure of your details

please use php tags, if you can't SEE php tags see my sig below for links to enable most bbcode on the forums here....

CODE

integer gIntBaseCount;

default{
  on_rez(){
     //-- turn off whatever you're doing
    gIntBaseCount = llGetNumberOfPrims();
  }

  changed( integer vBitChanges ){
    if (CHANGED_LINK & vBitChanges){
      if (llGetNumberOfPrims() - gIntBaseCount){
        //-- turn on whatever you're doing
      }else{
        //-- turn off whatever your doing
      }
    }
  }
}

this will cause the scrip to active only when people sit on it (and reactivate for each sitter) and turn off when no one is sitting on it

(if you see the tags, and not the indents, hit quote to see the indenting)

missing brackets
05-17-2009 02:43
unless there is a typo in your posting I can see 3 left curly brackets but only 2 right curly brackets. Are my eyes playing me up?
CODE

changed(integer change) 
{ // something change
    if (change & CHANGED_LINK) 
    { // and it was a link change
          // llSleep(0.5); // llUnSit works better with this delay
        key av = llAvatarOnSitTarget();
        if (av) 
        { // somebody is sitting on me
            llSay(0, "Get waxed!");
        }
gives me a Syntax error with this line:
    } //NEEDS THIS ONE ? 

}
