Summary
Function: integer llTarget( vector position, float range );| 66 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
This function is to have the script know when it has reached a position.
It registers a position with a range that triggers at_target and not_at_target events continuously until unregistered.
Returns an integer that is the handle to unregister the target with llTargetRemove.
| • vector | position | |||
| • float | range |
A similar function exists for rotations: llRotTarget
This function does not move the object, to do that use llSetPos or llMoveToTarget.
Caveats
Examples
<lsl> integer target_id; vector target_pos;
default {
state_entry()
{
target_pos = llGetPos() + <1.0, 0.0, 0.0>;
target_id = llTarget(target_pos, 0.5);
}
at_target(integer tnum, vector targetpos, vector ourpos)
{
if (tnum == target_id)
{
llOwnerSay("object is within range of target");
llOwnerSay("target position: " + (string)targetpos + ", object is now at: " + (string)ourpos);
llOwnerSay("this is " + (string)llVecDist(targetpos, ourpos) + " meters from the target");
llTargetRemove(target_id);
}
}
not_at_target()
{
llOwnerSay(
"not there yet - object is at " + (string)llGetPos() +
", which is " + (string)llVecDist(target_pos, llGetPos()) +
" meters from the target (" + (string)target_pos + ")"
);
}
