no unit requirment

[operation3000]

hello
i have a small problem with trigger
I need a no unit requirment like with the mothership in starcraft 2
but there is no no unit requirment in warcraft 3.
So i need to use my imagination this time
I created an upgrade named No Lurker (A player can control only one lurker at the time) and in trigger, ill make it researched or not researched if you have a lurker or no
Here is my problem
I made somes trigger like these one:
Trigger1
StartLurker
Events
Map initialization
Conditions
Actions
Player - Set the current research level of No Lurker to 1 for Player 1 (Red)
Player - Set the current research level of No Lurker to 1 for Player 2 (Blue)
...for all player

trigger 2
LurkerCREATION
Events
Unit - A unit Finishes training a unit
Conditions
(Unit-type of (Trained unit)) Equal to The Lurker
Actions
Player - Set the current research level of No Lurker to 0 for (Owner of (Triggering unit))

Trigger 3

LurkerDie
Events
Unit - A unit Dies
Conditions
(Unit-type of (Triggering unit)) Equal to The Lurker
Actions
Player - Set the current research level of No Lurker to 1 for (Owner of (Triggering unit))

My problem: When a lurker is trained, the no lurker requirment doesnt change to level0
So the no lurker condition failed
So i was able to make as much lurker i want
please tell me what is the problem in these trigger
thx
(oh and plz
tell me how to make trigger looking like in the world editor on THW)

Yes, you can't push back upgrade levels; in other words, upgrades cannot be degraded. To do what you want, use

• Trigger
• Events
  • Map Initialization
• Conditions
• Actions
  • For each (IntegerA) from 1 to 12, do (Actions)
    • Loop - Actions
      • Player - Limit training of Lurker to 1 for (Player(IntegerA))

To get "Player(IntegerA)", when it asks you for a player input, scroll to Conversion -> Convert Player to Player Index.

The unit will automatically become available for training, once it dies.

yea...
ill try it
but i think that when the lurker will die, the player will not be able to train another lurker, right?
