[Trigger] Unique Unit

[wereguy2]

Quick question, how would I make a trigger that states that only 1 of a certain type of unit may be in play at one time?
This is what I have, but it doesnt work...

• Single Unit
  • Events
    • Unit - A unit Finishes training a unit
  • Conditions
    • (Unit-type of (Trained unit)) Equal to [Unit]
  • Actions
    • Trigger - Turn on SingleUnitKill <gen>

• SingleUnitKill
  • Events
    • Unit - A unit Finishes training a unit
  • Conditions
    • (Unit-type of (Trained unit)) Equal to [Unit]
  • Actions
    • Unit - Remove (Last created unit) from the game
    • Trigger - Turn off SingleUnitKill <gen>

For a start you should remove (Trained unit) not (Last created unit)

 

[wereguy2]

yes, good point

EDIT Ohhhh, I think I know whats wrong, the unit is not trained, it is bought, how would I solve this???

• SingleUnitKill

• Unit - A unit Finishes training a unit
• Conditions
• (Unit-type of (Buying Unit)) Equal to [Unit]
• Actions
• Unit - Remove (Buying Unit) from the game
• Trigger - Turn off SingleUnitKill <gen>

Nevermind, I figured it out, instead of trains a unit, it is now unit enters entire map

It will leak if you have more than 1 unit that enters the map.

 

[wereguy2]

Nah, I tested it

 

[cHeRoL]

Ok,you know better what's going in your map .

 

[wereguy2]

Repped both of you

It will leak if you have more than 1 unit that enters the map.

Why will it leak and how to remove leak in this case (if i have no other way but to make trigger with event "unit enters region")?
