Im trying to issue a Unit Specific Unload command to a transport.

Ive read here that, for triggers at least, I would need to first set a TargetPassenger before actually issuing the order.

Im not entirely sure how that relates to the Issue Oder Effect, but Ive tried using an Iterate Transport Effect to get the Target Unit.

I was able to get the Unit and successfully tested this by using a Create Persistent (2 second delay) > Kill Effect.

(Unit enters, 2 seconds pass, unit dies)

But when I try to replace the Kill Effect with the Issue Order Effect, nothing happens. Not even an Alert.

(Ive tried both index 2 and 3 to no avail)

Any thought on how I can get the Issue Order Effect to unload the Target Unit?

Setting which to Target Outer?

Issue Order Effect? or the Iterate Transport Effect?

If Issue Order, which Field? There are two Unit Fields that can be set to Target Outer.

If you mean to get the Transport with Target Outer, doesn't Caster do that?

Or do you mean to get the Passenger with Target Outer?

Using Target Outer didn't work. I also tried Caster Outer, and in both Unit fields.

I got sick of blundering around with blind testing and set up a debug trigger.

I can now identify the Impact Unit, Launch Unit, Caster Unit, Origin Unit, Outer Unit, Source Unit, and Target Unit of ANY Effect I wish.

I Tested this with the Search Area Effect that calls the Issue Order Effect.

Result:

Impact - Cargo Unit

Launch - Cargo Unit

Caster - Cargo Unit

Origin - None

Outer - Cargo Unit

Source - Cargo Unit

Target - Cargo Unit

I then did a baseline test with the Issue Order Effect directly:

Ability Command - 1
Unit - Target

The result was:

Impact - None

Launch - None

Caster - Cargo Unit

Origin - None

Outer - Cargo Unit

Source - Cargo Unit

Target - Transport Unit

I then changed the Issue Order Effect to:

Ability Command - 3
Unit - Target
Target - Caster Unit

Target = the Transport Unit in the previous test, so should be the Unit receiving the order

Caster = the Cargo Unit in both previous tests so should be the Target of the order

The result?

Nothing. Nadda. No Alert, No nothin'...

I think I need to get it to set OrderSetTargetPassenger() somehow, like the other forum's post I linked to mentioned.

But I don't want to use triggers to do this... 

4 is Load all.

But I tried anyway:

Result: Nothing. No Alert. No actions.

EDIT:

On the plus side I learned what Ability Command 2 is.

It is Target POINT. I think it is used for moving transports so you can designate an unload point, then have the units unload as soon as the transport is within range of that point, rather than having to wait till the unit is in range and manually telling them to unload.

Unfortunately it is an Unload ALL command. :(

Try debugging with triggers. You can create an order listening trigger which prints out who was issued an order, what ability order was issued, the target type of the order, the target of the order (appropriate for type) and the internal order index that was issued.

Getting how to unload a specific unit would then be as easy as loading some units in a transport and manually unloading a single unit from it. The order you need to use would then be printed out and you can adapt your effect tree appropriately.

I already have a trigger that listens for Ordered Unit, Ability Command index, Order Target Unit, Order Target Unit Type, Ability Target Unit, and Ability Other Unit, but Im not sue what you mean by "ability order".

When I click the cargo slot to unload, the trigger returns the Ordered Unit(Transport), and the Ability Command Index(3), but nothing else.

I even tried adding a button to the command card, that linked to the 3rd Index of the Transport ability directly. But clicking that does nothing but make the button flash.

Is the transport issuing a cargo (or whatever type it is, I forget off the top of my head) ability order 3 towards the transported unit when unloading a specific unit?

As I posted above, the Transport is issued the following Order via Effect:

Issue Order Effect:

Ability Command - 3
Unit - Target
Target - Caster Unit

In this chain, Target = the Transport Unit and Caster Unit = the Cargo Unit.

This is what I tested with the debug trigger, which returned the Ordered Unit(Transport), and the Ability Command Index(3), and everything else None.

YEEES!

I have achieved the functionality I was looking for!

Note, I did NOT get the Ability Command Index 3 to work.

I just cheated:

Transport (Ability)=>

• Load Cargo Behavior - BuffA 
• Unload Validator - ValidatorA

BuffA (Buff Behavior)=>

• Initial Effect - EffectA

EffectA (Create Persistent)=>

• Period Count - 1
• Period Duration - 2
• Location - Caster Unit
• Period Effect - EffectB

EffectB (Set)=>

• Effects - EffectC
• Effects - EffectD

EffectC (Apply Behavior)=>

• Behavior - BuffB

EffectD (Issue Order)=>

• Ability - Transport
• Ability Command Index - 1
• Unit - Outer

ValidatorA (Compare Behavior Count)=>

• Compare - Not Equal To
• Value - 0

Technically, Im using Unload All, but just filtering which units get to unload via the Unload Validator.

Its a dirty dirty work around, and I hate that I had to use it. But it works, and does so without triggers so... YAY!
