Removing all instances of an entity before making a new one?

[Gook Nukem]

I'm making a Bioshock plasmid pack and I'm currently on the target dummy plasmid. In order for it to be replicated semi-successfully I need to allow only one target dummy entity on the map at a time. Can someone help me? Thanks! :)

[LauScript]

[lua]
for k,v in pairs( ents.GetAll() ) do
if ( v:GetClass() == "DummyTargetOrWhateverTheClassIs" ) then
v:Remove()
end
end
[/lua]

[b]Or[/b], when you create the entity do something like
[lua]ent = DummyTarget[/lua]

and then whenever you spawn a dummytarget entity you do a check..
[lua]
if ( DummyTarget ) then
DummyTarget:Remove()
end
[/lua]
