How to issue orders to a certain type of unit?

[Scippi]

Hey guys just wondering, how do i make a trigger which issues an order to all units of a certain type to attack move to a unit when an enemy unit enters a region ? I tried using the issue order actions but they all require me to specify a unit. Any help would be appreciated. Thanks in advance

• Trigger1
• Events
  • Unit - A unit enters Region 000 <gen>
• Conditions
  • ((Triggering unit) belongs to an enemy of (Player 1 (Red))) Equal to True
• Actions
  • Set Temp_Point = (Position of (the unit you want attacked))
  • Custom script: set bj_wantDestroyGroup = true
  • Unit Group - Pick every unit in (Units of type (unit-type here)) and do (Actions)
    • Loop - Actions
      • Unit - Order (Picked unit) to Attack-Move to (Temp_Point)
  • Custom script: call RemoveLocation (udg_Temp_Point)

Off topic: What's Custom script: set bj_wantDestroyGroup = true ?

Off topic: What's Custom script: set bj_wantDestroyGroup = true ?

It just makes it so that the group is destroyed after it is created. Basically, it will group the units and allow you to do the functions for those units, and then destroy the group. You can use either the Group - Destroy thing or bj_wantDestroyGroup.

Group - Destroy (or whatever the gui function is) is *technically* faster since bj_wantDestroyGroup leads to calling it anyway, but it doesn't really matter/make a noticeable difference.

Thank you guys that helped a lot

Ohh yeahh btw pharaoh how do i set temp_point to the location of the unit i want to be attacked?

Press Ctrl + B, or go to Edit - Variables... or the action "Set Variable", type the name of the variable (it can be anything, just make sure you use the same name in the Custom script i gave you afterwards) and make the type "Point". Click ok, until you get back to the trigger. References:

[Scippi]

So the game will automatically assume this temp point is the position of the unit that's gonig to be attacked?

 

[Pharaoh_]

Obviously
The points are mostly set in variables, to avoid what we call "leaks".

Ohh okay sweet thanks dude and for the issuing order, can i do this
Unit Group - Pick every unit in (Units of type Orc Militia) and do (Unit - Order (Picked unit) to Attack-Move To TempPoint)
Instead of having another action underneath the pick every unit bit?

 

[Pharaoh_]

Yes, you can. The one you use is for a single action, the other one is in order to add multiple actions that refer to the Picked unit.

 

[Scippi]

Another question, how do i do the custom script thing? xD

 

[Pharaoh_]

Just get the "Custom script" action and type everything you see after the "Custom script:".

 

[Scippi]

For the set temp_point thing, what do i set it to? position of triggering unit?

 

[Pharaoh_]

It depends. What unit do you want attacked? If you use Triggering unit, you will order every unit of type X to attack this entering-in-the-region unit.

 

[Scippi]

i want them to attack every enemy unit entering the region

 

[Scippi]

you still there pharaoh?

 

[Pharaoh_]

Then use the Triggering unit and use the Boolean condition to check if the Triggering unit belongs to enemy of (Owner of (Picked unit)).

 

[Scippi]

The spawned units don't seem to understand the trigger, they don't move at all when they spawn xD

• Orc militia attack
  • Events
    • Unit - A unit enters Attack region 2 <gen>
  • Conditions
    • (Owner of (Triggering unit)) Equal to Player 1 (Red)
  • Actions
    • Set TempPoint = (Position of (Triggering unit))
    • Custom script: set bj_wantDestroyGroup=true
    • Unit Group - Pick every unit in (Units of type Orc Militia) and do (Unit - Order (Picked unit) to Attack-Move To TempPoint)

 

[Pharaoh_]

Yes, because you create them at the same time with the spawning trigger, from the other thread of yours. You must create them, add them in a Unit Group and do it like this:
e.g.

• Trigger0
• Actions
  • Set Temp_Point = (Random Point in (Region 000 <gen>))
  • For each (IntegerA) from 1 to 5, do (Actions)
    • Loop - Actions
      • Unit - Create 1 Orc Militia at Temp_Point for (Player 2 (Blue)) facing default building degrees
      • Unit Group - Add (Last created unit) to OrcMilitiaGroup
  • Custom script: call RemoveLocation (udg_Temp_Point)

and then, after the creation of all of them,

• Unit Group - Order (OrcMilitiaGroup) to Attack - Move to (your point)

 

[Scippi]

I don't get this trigger, what was it meant to do? and what do i put for the do actions for the integer bit?
And also, the TempPoint is still set to the position of the triggering unit right?

Put the actions Pharaoh listed in whatever trigger your orc militia spawn trigger is. It spawns 5 orc militia at a random point in a region you specify. Then it adds them to a unit group.

After they are made, it allows that trigger you posted to happen.
