LlGetAgentSize

Function: vector llGetAgentSize( key id );

Returns a vector that is the size of the requested avatar by id.
• key id – avatar UUID that is in the same region

ZERO_VECTOR is returned if id is not in the region or if it is not an avatar.

Examples

//A simple script that makes a box hover above the owner's head. default {

   state_entry(integer i) {
       key owner = llGetOwner();
       vector pos = llList2Vector(llGetObjectDetails(owner, [OBJECT_POS]),0);
       vector agent = llGetAgentSize(owner);
       pos.z += 0.5 + agent.z / 2;//"pos" needs to be adjusted so it appears above the owner.
       if(agent)//makes sure it found the owner, a zero vector evaluates as false
           llSetPos(pos);
   }
   touch_start(integer num) {
       llResetScript();
   }

} </source>

Notes
• This function is a good way to quickly test...
-• if an avatar is in the same region.
-• if a UUID known to be in the region is an avatar.

To use this function to test either case use as follows

if(llGetAgentSize(uuid)) {

   //uuid is an avatar in the region

} else {

   //uuid is not an avatar in the region

} </source>

• The returned vector holds the size of the avatar's bounding box[1], of which only the height (z) varies. Width (x) and depth (y) are constant. (0.45m and 0.6m respectively).

  1. ^ In fact the returned height is much smaller than the bounding box height. It looks like the returned height is the height of the center of the avatar head above the ground/floor. To get the actual avatar height (counting shoes, and with a +/-3cm precision), add 0.17m (17cm).
