Trigger Help!

[Lurker6569]

Ok, im making a rpg. and im having a lil trouble with a trigger. I want the trigger to do this: When my "Harakim"(high templar)
"Ghost Companion"(Marine) dies i want it so when i go to the Inn it will create another one for him. please help me the trigger i have at the moment is this:

Conditions:
Current player brings exactly 1 Harakim to 'heal'.
Current player commands exactly 0 Ghost Companion.
Actions:
Create 1 Ghost Companion at 'heal' for Current Player.
Preserve trigger.


This trigger makes it so when i have 0 ghost companions and i go to heal it keeps creating them non stop. if i take preserve trigger away it only lets me create a Ghost companion once... please help me thank you

You have to use switches.

Yes, you must use a switch to cancel the the preserved action. An example is as follows:

CONDITION
Player commands at most 0 Marine
ACTION
Set 'Switch'
Preserve Trigger

CONDITION
Player commands at least 1 Marine
ACTION
Clear 'Switch'
Preserve Trigger

By setting and clearing the switch you are telling the game that the player either does or does not have a marine. Now that you have done that, you can make the triggers to create a marine:

CONDITION
Player brings at least 1 Templar to 'location'
Player commands at most 0 Marine
'Switch' is set
ACTION
Create 1 Marine at 'location'
Set deaths for Player: Subtract 1 for Marine
Preserve Trigger

Hope this helps

Whats the Set deaths action doing?

 

[Terranator3]

The Set Deaths trigger lets you modify the players death count.
In order for a preserved trigger to fire only once every time a condition is met you must oppose the 'positive' action with a 'negative' one.
In essence, by using the Set Deaths action, you are 'distracting' the games attention from creating units over and over again.
There are other methods of achieving this result, but the example I presented above is by far the easiest.

let me try to make this easier to understand. 'heal' will be the location where you bring the Harakim to get your ghost companion back

CONDITIONS:
'player' brings at least 1 'harakim' to 'heal
'player' commands exactly 0 'ghost companion'
switch 1 is cleared
ACTIONS:
create 1 'ghost companion' at 'location' for 'player'
set switch 1
preserve trigger

use this in combination with the previous trigger

CONDITIONS:
'player' brings exactly 0 'harakim' to 'heal'
ACTIONS:
clear switch 1
preserve trigger

this will make it so it will only make the ghost companion once and still be able to make it again if it dies
