Help with triggers

[Alowishus]

Hi,

This is going to sound really stupid but..

Take for example:

Unit - Kill (Triggering Unit)

How do i select the triggering unit? I have units placed on the map and there is no way to select them. I can't even find a way to select all the units of that kind as well.

It's the same for everything - selecting regions etc.

Help greatly appreciated.

you want the unit to be selected for a certain player so they can command it, or you want a unit to be selected in order to do things to it with triggers?

Well i need to write a trigger that when a unit enters a certain region that it dies but it still needs to be controllable by the player.

EDIT: When i say controllable by player i mean if the player steers it into said region and not it needs to be controllable after death lol.

If you want to be able to select stuff in the terrain editor then you need
to switch to the correct layer. Click on layer and you can select Terrain,
Units, Doodads, Regions ...
(Layer is a menu item right next to view)

If you select Units, then you will be able to place/delete/edit/select... units
but just units (units, items, resources .. all kind of units)
If you select Regions, then you will be able to select/edit/add/remove regions...
but just regions... and it goes on for all the other object types.

If you want to add/remove an unit to the player selection group in game
then you should check the trigger actions
Select Unit - Adds/Removes an unit to/from player selection group.
Select Unit Group - Adds/Removes an unit group to/from player selection group.
Clear Selection - Removes all units from a player' selection group.

There are more actions/functions that operate with player selection
I just can't explain them all.

If you want to check if a unit is selected by a player at the moment it
enters a region then you should use trigger with condition like this one:

Event 
    Unit enters region....

Comparison
    Value 1: Unit In Unit Group
        Unit: Triggering Unit
        Unit Group: Selected Units
            Player: Owner Of Unit
                Unit: Triggering Unit
    Operator: ==
    Value 2: true

Actions
    Unit - Kill (Triggering Unit)

This trigger will kill the unit entering the region only if it is selected by the player.
If the player sends the unit to the region and then selects something else the unit
won't die.
