How Do I Prevent Charm From Being Cast On Any Unit Besides Specific Unit?

I was trying to use a trigger like this. But I don't know how to refer to the target of the item being manipulated.
Trigger:
  • Prevent Lead Archer Misuse
    • Events
      • Unit - A unit Uses an item
    • Conditions
      • (Item being manipulated) Equal to EtherealBow
      • (Target unit of ability being cast) Not equal to Ethereal_Spawn
    • Actions
      • Unit - Change ownership of (Target unit of ability being cast) to Player 11 (Dark Green) and Change color

I tried using the "Unit - A unit Begins casting an ability" event, and the "(Ability being cast) Equal to Charm (Item)" condition. But that didn't seem to trigger at all.

What am I doing?:
For a quest on my map, you must weaken a boss. It is level 18. When you take 1k hit points out of it, it "delevels." You're suppose to get it to level 5 and then use this item on it. But I don't want people to abuse this item on other units.

Well, set the item ability to be able only to charm units under level 6 (therefore only those at 5 or lower will be valid targets).

K, well, you clearly didn't read the part about only using it on that one unit. There are other units that are under 6.
Thanks for the response.

You can use a dummy unit classification (like Ancient, Mechanic, etc). If the HP of the boss becomes lower than X and reaches level 5, add the classification to the unit (Add Unit Type, or something like this in GUI, or [ljass]UnitAddType(unit u, unittype type)[/ljass] in JASS/custom script) Then go to the object editor and edit the Targets Allowed part of the charm ability. This should work.

Another way I can imagine is a dummy ability that fires the proper event and can be interrupted. If it's succesfully casted, you create a dummy unit, add the dummy charm to it and order it to charm the boss.

I see your condition as "Not Equal to". That would tell me any unit but "Ethereal Spawn". I would think you'd want to make it == Ethereal Spawn? if that were the boss else make it only equal to the boss so trigger would only run if cast on boss?

Another observation is that "Unit uses an item" will allow you to check which "item was being manipulated" but there isn't an ability being cast to get a target from. I have run through all the events in the past and using an item can be registered via (Begins casting, stats effect, Uses item, Starts channeling, Finishes casting, etc) just not "Unit is issued order x"
Perhaps using a casting detection would be better as you could successfully check the target and the spell being cast.

This trigger is to prevent the item from being used on any unit but "Ethereal Spawn."

This is what the trigger looked like before I tried the trigger in my initial post:
Trigger:
  • Prevent Lead Archer Misuse
    • Events
      • Unit - A unit Begins casting an ability
    • Conditions
      • (Ability being cast) Equal to Charm (Item)
      • (Target unit of ability being cast) Not equal to Ethereal_Spawn
    • Actions
      • Unit - Change ownership of (Target unit of ability being cast) to Player 11 (Dark Green) and Change color

This may be me being Herpa Derpa (just woke up!) but
"This trigger is to prevent the item from being used on any unit but "Ethereal Spawn.""
That is exactly what the trigger is not doing.
(Target unit of ability being cast) Not equal to Ethereal_Spawn

Here's the other trigger for when the item is going to be used on the right unit. It too is not being triggered correctly.

Trigger:
  • Quest Finish Lead Archer
    • Events
      • Unit - A unit Finishes casting an ability
    • Conditions
      • (Ability being cast) Equal to Charm (Item)
      • (Target unit of ability being cast) Equal to Ethereal_Spawn
    • Actions
      • Unit - Change ownership of Ethereal_Spawn to Player 9 (Gray) and Retain color
      • Unit - Move Ethereal_Spawn instantly to (Player 9 (Gray) start location)
      • Unit - Move (Triggering unit) instantly to (Player 9 (Gray) start location)
      • Item - Remove EtherealBow
      • Quest - Mark QUESTREQUIREMENT[7] as Completed
      • Cinematic - Flash a speech indicator for Lead Archer 0051 <gen> of color (100.00%, 100.00%, 100.00%) with 0.00% transparency
      • Cinematic - Send transmission to PLAYING from Lead Archer 0051 <gen> named |cffC0C0C0Lead Arch...: Play No sound and display Good job. Now we ha.... Modify duration: Add 0.00 seconds and Wait
      • For each (Integer A) from 1 to 8, do (Actions)
        • Loop - Actions

This trigger works.
Trigger:
  • Ethereal Bow
    • Events
      • Unit - A unit Starts the effect of an ability
    • Conditions
      • (Ability being cast) Equal to Charm
      • (Unit-type of (Target unit of ability being cast)) Equal to Ethereal Spawn
    • Actions
      • Unit - Change ownership of (Target unit of ability being cast) to Player 1 (Red) and Change color

Can only be cast on Ethereal Spawn and changes the owner just fine.


Test map is for example. (Footman = Ethereal Spawn)
Try cast it on the footman and the other units

Interesting...
It doesn't exactly work the same as charm, but beggars can't choosers!

Thanks, inevit4ble.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
