Okay i've made this bridge that rotates when you click on the root prim. It rotates fine but it's just way too fast and i can't figure out how to slow it down. I don't want it to pause ten seconds or so - it would just be nice if it would take more time getting from frame 0 to frame 1 and back.

I was told to change the llsleep(delay) to llsleep(number); but this just tells it to pause for however long i tell it to.
I've tried going through my rotation scripts and such to see if i can get parts out of it but the script seems to reject it with an 'error.' Any way here's the script:

float delay=0.3;
string status="off";
go(){
llMessageLinked(LINK_SET,2,"p1","");
llSleep(delay);
llMessageLinked(LINK_SET,2,"p0","");
}

default
{
on_rez(integer r){llResetScript();}
state_entry(){
llMessageLinked(LINK_SET,2,"p0",""); //Start is at frame 0
}

touch_start(integer total_number)
{if(status=="off"){
status="on";
llSetTimerEvent(delay*6);
}else{
status="off";
llSetTimerEvent(0);}
}
timer(){go();}
}


Any idea if i'm missing something or need to change something? Like i said - i'd like to be able to change the ammount of time that it takes to get from point A to point B and back again.

Thanks again for your help, i've been trying to work it out all day i even looked on Google for answers before asking here.

This script only tells the other pieces what to do with llMessageLinked... perhaps post what the other script (in the pieces) says and someone could help?

That's your problem right there. An animation with 2 frames is more like just two static positions. I'm obviously aware that we're talking about object animation, but the same thing still applies.

luckily for you, this is one of my areas of expertise

The best way to do this. First of all, get your values for A and B. Position, rotation, and scale, if applicable.

The next thing you need to do is to interpolate them. This function suffices for position and rotation:

Note that frames here is a global variable which you'll need to set. I find 20 frames looks plenty good enough for most animations, but bear in mind that you're going to have a delay of 0.2 secs per frame. Decide how long (in seconds) you want the animation to take, and divide that number by 0.2 to get the number of frames you'll need. 20 frames will generate a 4 second long animation.

For rotation, it's in two parts

The slerp function is some fancy quaternion magic that I only sort of understand. it's the only part here that I didn't write from scratch. I translated it into LSL from a math website.

Once you run your data through these functions, you'll be left with 3 lists of positions, scales, and rotations. This processing will only need to be done once unless the start/end values change, so do it once and store the valuesfor reuse later.

You'll simply want to run through an llSetPrimitiveParams loop with the values from each element of the list, and the 0.2 inherent delay in the function will slow things down for you.

Lastly, bear in mind that this is all rather resource intensive. You're going to be sending an object update with every frame, and it can be a bit taxing on the sim. it's advised to only do in small parts as necessary, not something you should run constantly.
