Changing abilities

[AyeKantSpel]

Hello, it's been a while since I've modded and I've briefly tried to trigger a hero morph ability that also changes abilities as the hero morphs, right now it's based on metamorphosis and I have the ability to trigger a hero ability swap upon cast and a toggle of the triggers for each casted instance of the morph spell. If anyone could point out where I'm doing it wrong I would greatly appreciate it, thank you in advance.

Use "call MakeAbilityPermanent(DaUnit, DaAbility)" IIRC. if it didn't work change DaUnit place with DaAbility

First of all use "A unit starts the effect of an ability" as the event.
Secondly, I recommend you to change the abilities using Engineering Upgrade and add/remove it when the unit casts that ability.

When transforming a unit, your unit will lose all abilities that were given to him by triggers unless they are made permanent with that script Arad MNK showed.

Also, instead of this stupid turn off/turn on trigger thingy, you check if the triggering unit has the engineering upgrade ability.
If so, you remove it, otherwise you add it and make it permanent.
