[Spell] Metamorphosis & Engineering Upgrade

[Spear]

I had been attempting to make a spell which allows a hero unit to have his spells upgraded for a set time, the mechanism I intended to use was based on metamorphosis: the hero would use the spell to "transform" into an identical hero, but this one having the Engineering upgrade ability which upgraded 3 of his other spells. But I noticed that every time the time runs out the spells that have been learned before the metamorphosis spell had been activated all disappear leaving blank spaces. Does this usually occur or did I do something wrong? If this is typical is there another method of achieving the same result of having an ultimate spell that upgrades all of the other spells for a set period of time?

You need to use UnitMakeAbilityPermanent on the abilities added to the unit when they are added. Without using that they will disappear when morphing.

• Set UnitVar = (The unit)
• Set AbilVar = Holy Light (or whatever ability)
• Custom script: call UnitMakeAbilityPermanent(udg_UnitVar, true, udg_AbilVar)

I think you misunderstood.

I created 2 identical heroes with identical abilities except the 2nd hero has a renamed and reworked engineering upgrade that effects the other 3 spells. So the only ability that is "added" is the engineering upgrade but it is removed when the unit "morphs" back and along with it the abilities that are effected by it are removed...this is the problem.

Try adding and removing the EU with triggers when the spell is cast/ends, then. EU can be removed and the spells should go back to their un-upgraded state.

That works, thank you.

Still it would've looked better with an expiration timer, but this is satisfactory for the time being.

 

[Pyrogasm]

You can add the expiration timer yourself with a trigger. You should be able to use a morph ability too, just don’t give the morphed form the EU ability.

If the ability makes the regular hero abilities dissappear once it's expired you might just wanna use a trigger instead to add the engineering upgrade then set it to wait for 60.0 or however second you want the ability to last then take away the engineering upgrade.

If you want to still have an expiration timer make a copy of something like avatar adjust it properly then have the trigger take away engineering upgrade right before the expiration timer for avatar expires, those are just my thoughts and I have limited experince with the matter so take them with a grain of salt...
