Rotation scripting problem

I'm trying to make a chari cushion into a 'pose ball' but in order to get the guests to sit correctly, I need to rotate them because the cushion is rotated. I have been looking around for how to do it and found the following example code:

vector eul = <0, 0, 45>; // 45 degrees around the z-axis, in Euler form
eul *= DEG_TO_RAD; //convert to radians
rotation quat = llEuler2Rot( eul ); // convert to quaternion
llSetRot( quat ); // rotate the object

I've seen this in multiple locations, including the Wiki, and yet when I try to use it, I get syntax errors... The first of which is at 'eul *=' (40, 4) : Error : Syntax error.

I tried doing some tinkering but I'm getting other syntax errors between function names and open perens, etc. Any ideas what's going on?

Thanks!

The code you posted compiles fine for me.

Can you post your code here?

Bear in mind I'm just getting used to LSL, so right now I'm in the stage of using scripts I'm finding, and then modifying it to suit, while I get the hang of the new bells & whistles.

That being said, I'm currently experimenting with a pose ball script.. I've highlighted the scripting I've added with comments...

// position to sit on the ball e.g <0.0, 0.0, 0.43>

// hovertext above ball. "" for none.
// add '\n ' at the end to move text up i.e.

string HOVERTEXT="Sit Here";

// Pie Menu Sit Text. Will only work for the

string SIT_TEXT="Have a Seat!";


// hovertext color 'r,g,b' e.g. "255,255,255" (white)
string HOVER_RGB="255,255,255";

// LISTEN sets if this ball should listen for voice commands
// or not. You only need to enable this for 1 ball if you
// link several balls to an object. (to reduce lagg).
// Change to TRUE to enable FALSE to disable.

// What channel to listen for hide/show on. If you want to

Okay, I just found out where the syntax issue is coming from, Some of the code is in the wrong location within the script... So I guess now my question is why this section of code shouldn't be outside of the default state:

// rotation of avatar //
vector eul = <0, 0, 45>; // 45 degrees around the z-axis, in Euler form
eul *= DEG_TO_RAD; //convert to radians
rotation quat = llEuler2Rot( eul ); // convert to quaternion
llSetRot( quat ); // rotate the object

Code is either in functions or inside events. If you put code somewhere else, LSL has no idea when to actually 'run' it.

Btw, please surround posted code with the

 tags, to make it more readable.

Sorry about the readability... I'll be sure to do that from now on. I am just going to start from scratch and hope for the best on this. Thanks for your help!

You need to put your rotation code in the top of the state_entry event. And llSetRot will rotate the object, not the avatar, so you need to add your rotation to the sittarget:

state_entry()
{
    // rotation of avatar //
    vector eul = <0, 0, 45>; // 45 degrees around the z-axis, in Euler form
    eul *= DEG_TO_RAD; //convert to radians
    rotation quat = llEuler2Rot( eul ); // convert to quaternion

    if (llStringLength(SIT_TEXT)>0)
        llSetSitText(SIT_TEXT);
    llSitTarget(POSITION, quat);
    set_text();
    start_listen();
}
