[Trigger] how to create a unit give trigger

[bowserblaster455]

hello, is their a trigger that at when you begin to play a map, it gives unit's in a region to a player and one that when a hero enter's a region, it will give the owner of the hero unit's in a region and play a sound

For the map initialization you want something like this...

• Melee Initialization
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in Region 000 <gen>) and do (Actions)
      • Loop - Actions
        • Unit - Change ownership of (Picked unit) to Player 1 (Red) and Change color

When a hero enters the region you want it more like the trigger below. You can make it more specific as to a hero type, a hero owned by player etc...

• Untitled Trigger 001
  • Events
    • Unit - A unit enters Region 000 <gen>
  • Conditions
    • ((Triggering unit) is A Hero) Equal to True
  • Actions
    • Unit Group - Pick every unit in (Units in Region 000 <gen>) and do (Actions)
      • Loop - Actions
        • Unit - Change ownership of (Picked unit) to (Owner of (Triggering unit)) and Change color

use the event unit enters region.
use the condition to filter out the unit u want to trigger this.
in actions pick all units in the region. and for the group loop change the units owner.

edit: 13oot beat me to it.

u need to clean those group leaks tho. Also anything used twice or more should be stored in a variable. so store owner of triggering unit into a player variable.

oops I forgot about that, my mistake haha

EDIT: Also, why do you set the unit to a temp variable if you remove in fractions of a second anyways?

 

[deathismyfriend]

u set it to a temp variable for speed and efficiency.

Yeah I understand that but if it's only being used for one line wouldn't it be more work to set it and then remove it?

That depends on the variable. I myself use a different way of deciding. At first I don't store things in variables. Then I write them out all the times and once I get tired of writing them out THEN I use variables. I'm talking of JASS though.

 

[deathismyfriend]

i use variables from the start then anything i only use once i change to a none variable.

also yes he does not need to store picked unit. the other one owner of does need to be stored tho.
