GetAgentSize

llGetAgentSize

Summary

Function: vector llGetAgentSize( key id );

218	Function ID
0.0	Forced Delay
10.0	Energy

Returns a vector that is the size of the bounding box 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.

Caveats

• 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).

Examples

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

   state_entry() {
       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();
   }

}</lsl>

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 <lsl>if(llGetAgentSize(uuid)) {

   //uuid is an avatar in the region

} else {

   //uuid is not an avatar in the region

}</lsl>

Footnotes

1. ^ In fact the returned height is much smaller than the bounding box height. The "actual avatar height" can be approximated by using a multiplier of 1.10 to 1.125. You can test this by changing a prim to with llSetScale and compare the size.
