Summary
Function: rotation llGetRootRotation( );| 269 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a rotation that is the region rotation of the root prim of the object.
Caveats
- This fuction incorrectly (but usefully) returns the avatars region rotation when called in an attachment, use the following instead:
<lsl> //-- if called only from the root
llGetLocalRot()
//-- if called from in a linked object
llList2Rot( llGetLinkPrimitiveParams( LINK_ROOT, [PRIM_ROT_LOCAL] ), 0 )
//-- this alternative works correctly in all scenarios
llList2Rot( llGetLinkPrimitiveParams( !!llGetLinkNumber(), [PRIM_ROT_LOCAL] ), 0 )</lsl>
Examples
Simple example to set region rotation of child prim in unattached link set <lsl> default {
state_entry()
{
//Rotate 45 degrees about Y-axis
rotation globalRot = llEuler2Rot(<0.0, 45.0, 0.0> * DEG_TO_RAD);
llSetLocalRot(globalRot / llGetRootRotation());
}
}
</lsl>Notes
In an attached object, returns region rotation of avatar NOT of the object's root prim. See special cases of rotation.
