Giving Siege Engine Barrage a cooldown?

[Adonai1337]

So, I'm studying a bit of the basic in the world editor and messing around just for fun and decided to make some imbalanced changes to the normal melee units just to see how this new game would be.

I just started, but already got stuck in my flying machine: I tried giving it barrage/split shot with a cooldown. I managed to make barrage work on it and shoot even structures as I had intended but I can't find a way to put a cooldown on it. I tried the OoL method, because it's a single unit using an onAttack procc but that doesn't change anything (other than allowed me to change the projectile art for the main shot)

Is there even a way to do so?

Disclaimer: I really suck on triggers, coding and even some files names, I literally just started playing around with this kind of map making

What I had in mind was to create a hidden barrage and a dummy ability based on that barrage. What the dummy ability does is show you the cooldown of the hidden barrage while simultaneously running a timer with the exact duration based on the object data. When the timer expires, add the ability to the unit, and when the unit has successfully cast its' backswing animation when attacking, remove the ability.

To be honest, this seems quite complex for you to do, but that's jut my point of view.

Maybe man, thanks for the reply!

Could you do it though? I'm actually very interested in learning that kind of stuff, so if you or someone else could just put it together on a blank map for me to see it, I'd really appreciate it.

Really just need a "look in the triggers" kind of note

Also gonna leave it open a little bit more, just in case someone else will be able to help me more

Orb of Lightning (new)?

So you want to replicate DotA's Flak Cannon ability.

It's based on a dummy ability (to show cooldown) and adds barrage + an expiration timer, which removes the barrage ability once it runs out.

It's very easy to make, just google a little more.

So, a dummy ability to Trigger an upgrade (adding barrage), this upgrade expires on a timer, on the expiring of the timer a new trigger removing the barrage?

Also, is there a way to make it work for a set amount of attacks, in my case 1?

You'll need a damage detection system to know when a number of attacks has happened, because, if you use the event, " A Unit is Attacked " a unit can cancel their attack and it would improperly remove the effect.

Also it's not really triggering an upgrade, it's more the barrage ability is added when necessary and removed when not, an upgrade cannot be "un-upgraded" so that is the reason for adding and removing.
