Summary
Function: llFleeFrom( vector position, float distance, list options );Directs a character to keep a specific distance from a specific position in the region or adjacent regions.
| • vector | position | – | position in region coordinates from which to flee. | |
| • float | distance | – | Distance in meters to flee from position. | |
| • list | options | – | No options available at this time. |
Caveats
- Must use llCreateCharacter or script won't compile.
- The position to flee from must be near the nav mesh; otherwise, this behavior will fail and trigger path update with PU_FAILURE_INVALID_GOAL.
- If you want to avoid an agent or object as per the example below, it's much more elegant and less sim resource intensive to use llEvade instead.
Examples
vector last_touched_pos;
key last_touched_key;
default
{
state_entry()
{
llCreateCharacter([CHARACTER_DESIRED_SPEED, 50.0]);
}
touch_start(integer total_number)
{
last_touched_key = llDetectedKey(0);
last_touched_pos = llDetectedPos(0);
llFleeFrom(last_touched_pos, 10, []);
llSetTimerEvent(0.2);
}
timer()
{
vector last_touched_pos_now = llList2Vector(llGetObjectDetails(last_touched_key, [OBJECT_POS]), 0);
if ( llVecDist(last_touched_pos, last_touched_pos_now) > 1 )
{
last_touched_pos = last_touched_pos_now;
llFleeFrom(last_touched_pos, 10, []);
}
}
}
Notes
The position vector can be set outside the current region by using extended range region coordinates: e.g., to avoid the SE corner of the region to the East of the current one, you could
llFleeFrom(<0.0, 512.0, 0.0>, 20.0, []);
