There is a short and very simple solution
First add this small script :
class Game_Actor < Game_Battler
#--------------------------------------------------------------------------
# * Public Instance Variables
#--------------------------------------------------------------------------
attr_reader :actor_id # actor ID
end
Now in an event , you can use :
Call script :
tp_actor_id=$game_party.members[1].actor_id
$game_party.remove_actor(tp_actor_id)
$game_map.need_refresh = true
The "1" is the 2nd party member (the index start at 0) .
You can remove the actor you want with that (and yes , also cloned actors) .
