How to make Special Spell

[Dinan]

hello guys, sorry for my english

i want to ask how to make a special spell
like so

My hero doing a special move that pause the caster and the unit, and make them both invulnerable. After the special move end, dealing damage to the target.

like most of 5th skill on bleach versus onepiece map.

short example:
Like arthas, he doing attack animation 5 times. ( i can't move or using any command to arthas, so do the target. Also make them both invulnerable so the enemy can't attack the caster and the target)
after the animation ends. it deals damage to the target and make the unit to normal, can move, and vulnerable)

how to make spell like that?
thanks

You use triggers and script what you want to happen. TriggerSleepAction is likely not sufficient for the timing so you will want some sort of state machine that advances every iteration of a periodic trigger or timer.

Base it off of Aerial Shackles. That will prevent both from moving. Make sure it can target invulnerable. Then:

A unit begins channeling an ability
Ability equal to [your skill]
Make target/caster invulnerable

A unit stops channeling
Ability equal to [your skill]
Make target/caster vulnerable

You'd need a timer to check that he channeled the full duration before doing the damage. This would also allow canceling early without dealing damage (this could be good or bad depending on what you want).

Another alternative is using the Unit - Pause command with a normal unchanneling skill but I don't like this because of the strange behavior of Pause Unit.
