[Spell] how to give conditions to a spell properly?

[Lender]

Hey. I was wondering about how can i make custom requirements
i don't asking about how to check things for triggered spells

but how to set requirements for them if they fail, the spell will not get active

I mean , like a spell with a target , the "targets allowed" are "ground,enemy,etc..."
so u cant cast it on a friendly unit.. this is default in WC

but what I'm trying to do is a spell that requires windwalk buff for example

or spells that can be casted from behind enemy

and if they fail , nothing happens
like it wont break windwalk and wont set the ability on cooldown like with simple triggered conditions

I think you can detect when they are casted if all the requirements are good or not.

If yes, you do all the actions. If no, you just regen the mana and you refresh the cooldown of this spell. (remove/add ability / maybe)

that will brake windwalk
this is my main problem

tried with setting spells "disable other abilities" to false but didn't help me out

You can also use "Disable/Enable ability for Player" GUI action.

it doesn't really matters what I do, cus till I do it in the Trigger it will break windwalk

 

[Vladadamm]

This won't break windwalk. When the unit cast windwalk, you enable the ability and when the unit end the windwalk, you disable the ability.

well the point is that the spell i need can be casted from behind the enemy
but can be casted while not windwalking . the point is it does extra damage while windwalking
And i need it to not interrupt windwalking occasionally casted on the front of the enemy
and to be able to trigger if the unit is actually windwalking, cus if i check it in a trigger after the casting started it will never be triggered since the windwalk buff already broke.

anybody has any idea how to do this?
