Help with a random rotation vector script?

[Gawain Galtier]

Hello!

I am trying to create a script that makes an object rotate in random rotations several times / as a visual effect. I created a list of the rotational vectors that I require to use, and I'm hoping to pull them randomly into use. I am getting an error message and I can't figure this out. Here's what I have:

 

//list of rotations
list t_rot= ["<-0.05234, 0.00000, 0.00000, 0.99863>", "<0.04363, 0.00000, 0.00000, 0.99905>","<0.00000, 0.06105, 0.00000, 0.99813>","<0.00000, -0.04364, 0.00000, 0.99905>"];
      
t_fx()
{
    //l
    llSetLinkPrimitiveParams(3,[PRIM_ROTATION, llList2String( llListRandomize(t_rot, 1 ), 0 ), PRIM_POSITION, <-0.00035, -0.00040, 0.00346>]); 
    //2
    llSetLinkPrimitiveParams(3,[PRIM_ROTATION, llList2String( llListRandomize(t_rot, 1 ), 0 ), PRIM_POSITION, <-0.00035, -0.00040, 0.00346>]); 
    //origin
    llSetLinkPrimitiveParams(3,[PRIM_ROTATION, <0.00000, 0.00000, 0.00000, 1.00000>, PRIM_POSITION, <-0.00035, -0.00040, 0.00346>]); 

}
 
default
{
    state_entry()
    {
    }
    on_rez(integer start_params)
    {
    }
    link_message(integer sender, integer num, string messg, key id)
    {
        if ( num == 344 && messg == "t_fx")
        {
            //visual effects
            t_fx();
        
        }
    }
}

 

I tried using the llList2Vector but that didn't seem to work either. Any advice available?

How about llList2Rot()?

You are not saying one word about what error you have so I am guessing
You have a not normalized quaternion which is likely to happen when you cast from a string

See Normalizing a Rotation to solve this problem

Well spotted except llList2Rot() doesn't work, See the work around here

Yeah I know. :matte-motes-big-grin: It was just a quick hint (because I'm in a hurry) to better apply a rotation when a rotation is required, rather than applying a string. Why the rotation vectors are stored as strings in the list is another question. Also the usefulness of the script as is is questionable anyway, becaus it will always apply the rotation in the last llSLPPF call anyway.

 

So I suspect this will take a little longer to get it all straight. :matte-motes-wink:

Thank you so much!

 

The llList2Rot worked instead of the llList2String. Problem solved. Thank you so much
