Returns a rotation that is the prim's rotation relative to the region plane.
Caveats
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>
Notes
llGetRot in Mouselook (see llForceMouselook) for an attachment returns the angle the avatar is looking in.
