[Need Info] Enable/Disable certain abilities from a Learn ability

[MantisHair]

I have a Learn ability that holds large numbers of abilities for one hero. The idea is that learning one ability of a certain kind (for example, an ability that detects cloak/burrow) prevents learning other abilities with a similar purpose. I don't see a Validator for this, and I don't know enough about Requirements to know if those will work.

Any ideas? (The simpler the better, mostly.)

well you could make an array grouped abilities linked to trig

if a spell is learnt from group A, disable all other spells in that group from the tech tree

disabling abilities in the tech tree is how you disable spells from being learnt.

do you know trig

Requirements should solve it. Ability type queued or better on unit is greater than 0 means the ability is learnt. As such for your show requirement you want "and" of all your abilities of the same type having queued or better equal to 0 (not learnt). If a single one of them is then learnt the and will evaluate false and so the ability will not be shown in the command card.

TheLordOfChaos201: I know how to use triggers for this, but it's a last resort. I'm much more comfortable with data.

Dr Super Good: Thank you, I thought requirements were the way to do it, but had no idea how to actually use them. Should look like this, right?(the attached image)

Yes that looks like what I would expect. Does it work?

If not then maybe it is a different sort of test node that is needed (I would have to check from an existing map which does something similar).

It's not working. I think I need to arrange it a bit differently. A requirement with a similar setup to this for each ability, but only the other two abilities under the "And".

EDIT:
I found a method that works, one of these for each ability. Learning ability A disables B and C, and so on - it's basically the same as the setup from Dr Super Good, with some tweaking. (See the attached image.)

Just to make it clear what the difference between show and use is...
Use -> If fail then button appears greyed out and show a requirement when hovered over.
Show -> If fail then button does not appear at all.

Some times show can be useful for hiding buttons that are no longer relevant. For example if a player chooses to go down mutually exclusive "upgrade path A" then you can hide anything relevant to "upgrade path B" to declutter the command cards.

I'm using "Use" because I want the whole command card visible while I'm developing a map/mod. Also, I like having the player being able to see the other options, because I'm planning to make a skill point re-spec method. That way, if someone feels like they chose the wrong path, they can still see the other options and make a better decision.

Of course, I can change it to "Show" if I think the learn menu card is getting too messy.

Also, those zeros under the requirement tooltip, is there a way to make those not show? (see attached image.)

Not that I know of, next to the obvious of hiding the entire button with the show tree. You can add additional text to the requirements so that maybe the 0 would make more sense.

It's been quite a while, I almost forgot to update about this.
I did find a solution, I'll tweak it so it doesn't look this rough (as in the attached image). Giving the zero constant requirement a tooltip replaces the number zero with a bit of text.
