How to Check Ability w/o using JASS and ...

Any souls out there that can help me with this 2 problems?

1) How do I check whether a Hero has a specific ability on him without using JASS? I thought of using string arrays, like storing the abilities that a Hero has onto a string arrays. Blizzard seems to left out this function...

2) How do I make the Hero with all 4 chosen abilities return to its starting stage? Meaning like when a new Hero is created, he has 1 skill points to use and he has 4 abilities (3 + 1 ultimate) to use on... This would mean I have to disable the 4 abilities and make them return to 0 skill pts state.

Please help...thanks...

1) Unit - Level of ability for unit. returns 0 if the hero doesn't have the ability.

2) Look at the tome of retraining, prehaps?

edit: what Grater said.

Thanks for the reply, but I can't seem to find the Unit-Level of Ability in the worldeditor... is there something wrong with my version? Is it in the Actions section?

Please tell me how to implement Unit-Level of Ability... thanks.

Its in the conditions tab (obviously, look at the form), and looks like this:

(Level of Attribute Bonus for (Triggering unit)) Equal to 0

Its TFT only, of course.

So, if you want a hero to have an ability for your trigger to work, you use equal to or greater than 1.

It's a function that appears whenever you are dealing with integers (Integer comparison, Set variable, etc.)

It wouldn't make much sense to be an action. You can't Level of Ability something.

oic... thanks for the replies! This site is great! 8)
