The subtle reality of the universe cannot be described, that which can be described in words is merely a concept of the mind.

No, but you can program one yourself.

For example, you can retrieve the 3D position of where the mouse clicked on the object:

+ Code Snippet

rem get the object the user is clicking
obj = pick object( 1, 1000, mousex(), mousey() )

rem get coordinates
if obj
   click_x# = get pick vector x() + camera position x()
   click_y# = get pick vector y() + camera position y()
   click_z# = get pick vector z() + camera position z()
endif

Since you know where the user clicked in 3D space, it won't be too hard to find the limb closest to the click.

What about making a transparent dummy cube for each limb, position it to that limb's xyz coords, reference the dummy object to the specific limb's ID, then click the dummy object to select the limb?

It might not be as pretty, but it should work better than trying to find the limb by name in a list.

Some quick Psuedo code for the above method:

+ Code Snippet

type dummyCubeType
   x# as float
   y# as float
   ObjID as integer
   LimbID as integer
endtype

DoAChecklistForLimbs
LimbCount = totalLimbsInObject
Dim DummyObject(LimbCount) as dummyCubeType
for i = 1 to LimbCount
   DummyObject(i).ObjID = 1000 + i
   make object cube, DummyObject(i).ObjID, 10
   DummyObject(i).x# = limb position(i).x#
   DummyObject(i).y# = limb position(i).y#
   DummyObject(i).z# = limb position(i).z#
   DummyObject(i).LimbID = limb(i)
   position object DummyObject(i).ObjID, DummyObject(i).x#, DummyObject(i).y#, DummyObject(i).z#
next i

obj = pick object( 1001, 1000 + LimbCount, mousex(), mousey() )

for i = 1 to LimbCount
   if obj = DummyObject(i).ObjID
      select limb(DummyObject(i).LimbID)
   endif
next i

Just a quick thought on the problem. Good luck!

Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.

Hi there.
What about checking for limb collision...perhaps a little bit slow but works.

autocam off
sync on
hide mouse

`making 10 objects to add as limbs to the main one
for i= 1 to 10
  make object box i,40,2,40
  position object i,rnd(100),rnd(100),rnd(100)
  rotate object i,rnd(360),rnd(360),rnd(360)
  make mesh from object i,i
next i

`making the final object to add all limbs
make object box 11,0,0,0

for i= 1 to 10
   add limb 11,i,i
   offset limb 11,i,object position x(i),object position y(i),object position z(i)
   delete object i
next i
color object 11,rgb(200,0,200)

`intersect object
make object sphere 2,2:color object 2,rgb(255,0,0)

position camera -50,50,-50

`moving camera 1000 units and saving coords. after moving
move camera 1000

lx#=camera position x()
ly#=camera position y()
lz#=camera position z()

`moving camera back after saving coords.
move camera -1000

`distance is checked with both saved coords.
dis= intersect object(11,x#,y#,z#,lx#,ly#,lz#)

`camera control.
