Used to get a point on the navmesh that is the closest point to point.
containing a single vector which is the closest point on the navmesh to the point provided or an empty list.を list で返します。

• vector	point	–	A point in region-local space
• list	options	–	GCNP_* and other flags with their parameters. See options table

If an option is not explicitly set, the default value for that option is used.

Options	V	Parameters	Default	Description
[ GCNP_RADIUS ]	0	[ float distance ]	[ 20.0 ]	Limits how far out to search for a navigation point.
[ GCNP_STATIC ]	1	[ integer use_static_mesh ]	[ FALSE ]	Specifies whether the test should use the static or dynamic nav mesh. In the static case, all dynamic obstacles are ignored.
[ CHARACTER_TYPE ]	6	[ integer type ]	[ CHARACTER_TYPE_NONE ]	Filters nav points by eliminating nav mesh faces which are 0% walkable for the specified character type. In the default CHARACTER_TYPE_NONE case, all nav mesh faces are included.

警告

• There is no guarantee that a path exists from your current location to the returned point.

サンプル

create_character()
{
//  Clear any previous character behaviors
    llDeleteCharacter();

//  default speed is 20
    llCreateCharacter([CHARACTER_DESIRED_SPEED, 10.0]);
    llWanderWithin(llGetPos(), <64.0, 64.0, 2.0>, []);
}

default
{
    on_rez(integer start_param)
    {
        llResetScript();
    }

    state_entry()
    {
        create_character();
    }
 
    touch_start(integer num_detected)
    {
        vector currentPos = llGetPos();
        list points = llGetClosestNavPoint(currentPos, [GCNP_RADIUS, 10.0] );

        if (!llGetListLength(points))
            return;

        llSay(0, "current position " + (string)currentPos
            + " and closest nav point " + (string)llList2Vector(points, 0) );
    }
}

注意点

Using the method incurs a one frame script sleep and the call can be extremely expensive. It is intended to be used in response to a path_update message indicating an inability to reach a requested destination (e.g., because the character or the destination is off the mesh).
