Trouble with basic "buy ability" trigger

[epaemil]

I've been following the guide - Buying abilitys - and have a few questions.
In the first trigger, he uses "Set skill[(Player number of (Owner of triggering unit))] = Inferno". I can only find Set VariableSet skill and I cannot find just the spell "Inferno" anywhere. I can also not find (Level of skill[(Player number of (Owner of triggering unit))] for (Triggering unit)) Less than 1). I just don't know where to find these specific commands when making triggers. Please help!

That thread is from 2007 so it's safe to assume it's very outdated. That being said, a lot of things stayed the same over the years.

Anyway, skill is an Ability Code variable with an Array (little checkbox enabled that adds these brackets []).

Set VariableSet is the same thing as Set, it's just that Reforged is buggy. It went from just the word Set to Set Variable to now Set VariableSet which is a typo that will probably never get fixed.

(Level of skill[...]) is a Condition found under the Integer Comparison category. It's called "Unit - Level of ability for unit". You can always tell which category a Condition belongs to by it's value, for example:

Less than 1 <-- 1 is an Integer, therefore it's an Integer comparison.
Greater than 1.24 <-- 1.24 is a Real, therefore it's a Real comparison.
Equal to True <-- True is a Boolean, therefore it's a Boolean comparison.

I would try to find a newer tutorial, that one looks pretty bad in my opinion. Those 0.20 second Waits look very unnecessary.
