warning if number of units enter region

[Total_Warrior]

Ok i need a trigger for my lord of the rings map:when 20 units are in a region it shows a warning ''The walls are being overrun!'' i can do the warning part but i dont know how to do the 20 units in the region part

I would do it with 2 simpel triggers. Note that "i" is a variable, and its an integer.

• Events
  • Unit - A unit enters Region 000 <gen>
• Actions
  • Set i = (i + 1)
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    • If - Conditions
      • i Equal to 20
    • Then - Actions
      • Game - Display to (All players) the text: Warning BLAH BLAH B...
    • Else - Actions

• Events
  • Unit - A unit leaves Region 000 <gen>
• Conditions
  • i Greater than 1
• Actions
  • Set i = (i - 1)

Lol not too hard..

• OverRun
  • Events
    • Unit - A unit enters (Region for wall)
  • Conditions
  • Actions
    • Set Overrun = 20
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in (Units in (Region for wall))) Greater Than Or Equal To Overrun
      • Then - Actions
        • Game - Display to (All players) the text: The walls are being...
      • Else - Actions
        • Do nothing

MeKC is true,
And you need global integer variable if you wanna to make it for several players.

P.S. You also can check number of units matching condition in region when unit enters region instead of creating another global variable.

You could simply just make the trigger:

Event: A unit enters *region*

Cond: If number of units in *region* greater than or equal to 20 (you can change it to find # of same units or any units)

Then do the rest of the actions, works without a variable and will repeat.

Cond: If number of units in *region* greater than or equal to 20 (you can change it to find # of same units or any units)

It's what I wrote in postscriptum of my previous message in this thread...
But if you'll make this condition, it can cause message to appear with several seconds delay. So if you want it to be shown fast, MeKC's way is the best.
