[Trigger] Why does this trigger not like variables?

[Nikkone]

• Events
  • Player - Player (1) Red types a chat message containing -revive As an exact match
• Conditions
  • (SeedofR <gen> is on) Equal to True
• Actions
  • Blah blah blah

In events, why will it not allow me to select a variable for Owner of Unit (Instead of player 1 - red) no matter what variable type it is? It's only letting me select units that have already been generated on the map.

that event is a player chat event...

that event cant be used with units because the player has to type in a chat event...

it would help if u also say wat u r trying to do

That event can be used with units. Owner of (Unit) types a a chat command. The problem is, I want to use units under a variable which it's not letting me do.

And the actions are irrelevant to my issue.

 

[deathismyfriend]

owner of unit is a player chat event. it gets the owner of a specific unit.

u cant use variables for that it needs to be pre-placed units.

Actions are always relevant as there may be a better way to do wat ur trying to do.

Have you tried using this action?

• Trigger - Add to (Your Trigger) the event (Player - (Owner of (Triggering unit)) types a chat message containing -revive as An exact match)

ya he can do that for units that arent preplaced

Or, instead use an ITE and check if triggering player is owner of unit.

That's y I said this is not needed.

This is a player event so if u register player 1 for the event it will only fire for player 1. Checking if the triggering player is player one is useless since it will only fire if it is player 1

 

[Vinz]

Well ofcourse I meant to add all the players 2 to 12

It would also work in case he did not put the unit into a var.

 

[deathismyfriend]

Well the problem is this is a player event there is no triggering unit. There is only a triggering player.

Okay thats it in terms of versatility(and MUIness)..

Because the native that generates the event object uses pass-by-value arguments so it is forced to use whatever value it is passed when you call it. Yes you can use variables or even other natives to get the values, but only the value they evaluate to at the time of the call is used to create the event object and that event object will continue to use that value until the end of the trigger's life (the trigger is destroyed) in which case the event object is also destroyed.

JASS is functional/procedural, not declarative so you cannot get it to resolve stuff when required. Owner of a unit returns a player and it is that player value that is passed around. It does not pass around a reference to a function/method that returns a player which is evaluated on demand.
