Summary
Function: rotation llGetRot( );| 62 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a rotation that is the prim's rotation relative to the region's axes.
Caveats
- llGetRot incorrectly reports the avatars rotation when called from the root of an attached object, see Useful Snippets for a workaround.
Examples
<lsl> //-- rotates an object to face the nearest cardinal direction (N,E,S,W)
//-- assumes build is aligned to root object facing
default{
state_entry()
{
llSay( 0, "Rotate me in edit, then touch to make me face the nearest compass point" );
}
touch_start( integer vIntTouches )
{
//-- convert our rotation to x/y/z radians
vector vRadBase = llRot2Euler( llGetRot() );
//-- round the z-axis to the nearest 90deg (PI_BY_TWO = 90deg in radians)
llSetRot( llEuler2Rot( <0.0, 0.0, llRound( vRadBase.z / PI_BY_TWO ) * PI_BY_TWO > ) );
}
}</lsl>
Useful Snippets
<lsl>//-- Workaround for attachment bug in root prims llGetLocalRot()
//-- Workaround for attachment bug in root prims (rotation)((string)llGetPrimitiveParams( [PRIM_ROT_LOCAL] ))</lsl>
Notes
- The tooltip in the in-client editor is incorrect, it will work in scripts in objects that are physical.
