LlFleeFrom

Wiki description

Directs a character to keep a specific distance from a specific position in the region or adjacent regions.

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, []);

Template:LSL Function/position

Original shared helper source (conditional wiki logic is not evaluated)

{{LSL Injection Test}}<noinclude>
This template is to be used to specify setup the description for position like parameters (offsets, positions, points, etc.).

Right now it's pretty basic and easy to edit. I'm wondering if these functions should be in a position parameter specific category.

====TODO====
* add clamping flag and verbiage for out of region/range coordinates.
