[Trigger] Can you detect a button click?

[GenFrogKing]

I want to be able to detect when a player clicks a button in the gui. For example,

if Some player clicks (button:Chain Lightning)
then... do this... (in addition to whatever the button would normally cause to happen)

or something very similar at least...

How can I do it? Will this require JASS? I feel like this is a novice question, but I've struggled in determining a solution through tinkering or forum scouring!

Edit: Here's the answer. (Assuming we want to detect an ability being pressed, this is similar to an ability being used. A separate trigger will be needed for other GUI.) Use the "channel" ability to have max control over the customization of your ability. To use multiple channel abilities on the same unit, simply change the "Date - Base Order ID" for each one so that the ID is unique per ability. In triggers then put...

• Events
  • Unit - A unit Begins channeling an ability
• Conditions
  • (Ability being cast) Equal to [Your Ability]
  • (Whatever conditions you want)
• Actions
  • (Whatever actions you want)
  • Refer to the unit as "Triggering Unit"

Wait, I think I solved it!

• Events
  • Unit - A unit Begins casting an ability
• Conditions
  • (Ability being cast) Equal to Upgrade Health (item)

don't use begins castring an ability

use starts the effect of an ability instead

 

[GenFrogKing]

Do I still refer to the ability as "ability being cast?"

Do I refer to the unit as "Casting Unit?"

Well, yes. But it's better in numerous way to refer to "Casting Unit" as "Triggering Unit" instead.

Okay, it appears to be working sometimes depending on the ability I use. For example, if I repurpose "Flare Gun," then whenever I use this ability in game, the trigger runs its effects successfully. However, when I repurpose a spell like "Magic Defense" nothing happens. (Ideally, I'd like to reuse an ability that requires only a single click instead of click, select target.)

What's going on here?

I have carefully tracked my changes so that all objects and triggers are referring to the appropriate things over my tests.

Okay! Finally got everything to work!

Thank you soo much. I guess "Magic Defense" is buggy? Or maybe just different. I ended up using "War Stomp" and everything works perfect.

Thank you again for your help! I'll edit my first post to give the answer to the problem just in case anyone else comes wondering the same thing.

If you want an ability that requires no target and does nothing (as you trigger everything around it), then use the Channel ability. It's made exactly for triggered spells.

 

[GenFrogKing]

Cool! Now using channel- required some tweaking in the triggers- and everything is working. One last question and we can call this discussion a wrap.

I'll need six instances of this channel ability. What is the best way to go about doing this so that all six don't try to fire simultaneously?

 

[GenFrogKing]

Nevermind, it has been discovered! Just change the "Data - Base Order ID."

Please do not double post it is against the rules. Also never use casting unit use triggering unit.

 

[GenFrogKing]

apologies.

Lil necro here, haha. Just a note.

Magic Defense is toggled, like Defend/Mana Shield/Immolation. So it doesn't really count as using an ability. You can try orders though.

A question; how did you detect Chain Lightning button click with your trigger?
