Summary
Function: integer llRotTarget( rotation rot, float error );68 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
This function is to have the script know when it has reached a rotation.
It registers a rot with a error that triggers at_rot_target and not_at_rot_target events continuously until unregistered.
Returns a handle (an integer) to unregister the target with llRotTargetRemove
• rotation | rot | – | target rotation | |
• float | error | – | angle in radians, defines when rot has been reached |
A similar function exists for positions: llTarget
This function does not rotate the object, to do that use llSetRot, llRotLookAt or llLookAt.
Caveats
Examples
<lsl> vector standrot = <0.0, 0.0, 0.0>; vector fliprot = <45.0, 0.0, 0.0>;
// simple two-state rot target detection and rotation by Hypatia Callisto // works, to detect a rotation target. An example I wrote // since there is almost zilch for clean examples for // at_rot_target, not_at_rot_target, llRotTarget, llRotTargetRemove
integer rottarget;
default {
state_entry(){ rottarget = llRotTarget(llEuler2Rot(fliprot*DEG_TO_RAD), 0.1); llSetPrimitiveParams ([PRIM_ROTATION, llEuler2Rot(standrot*DEG_TO_RAD)]); // rotate to starting point }
not_at_rot_target() { llRotTargetRemove( rottarget ); llOwnerSay("not there"); //not at target } touch_start (integer total_number) { state rotatestate; // change to state for new position }
}
state rotatestate
{
state_entry(){ rottarget = llRotTarget(llEuler2Rot(fliprot*DEG_TO_RAD), 0.1); llSetPrimitiveParams ([PRIM_ROTATION, llEuler2Rot(fliprot*DEG_TO_RAD)]); // rotate to new point } at_rot_target(integer tnum, rotation targetrot, rotation ourrot) { llRotTargetRemove( rottarget ); llOwnerSay("there"); //reached the target }
touch_start(integer touched){ state default; }
}
