Upgraded unit lost Spell Book (Bug?)

[CaptainHero]

I encountered a bug..
I have a unit, a tower for example that can be upgraded.
Both units have the same spell book.
But the upgraded unit seems to have lost its spell book.
Anyone knows how to fix this?

I also en counter problems giving the upgraded unit the ability back via triggers..
An upgraded unit doesn't seem to be "finished with construction" nor did it "enter the game" or "finished researching".. - how can you determine the upgraded unit?

Thanks in advance!

Have you tried call UnitMakeAbilityPermanent(udg_YourUnit, true, udg_AbilityID) ?

To see the ID of the ability, go to Object Editor -> Abilities Tab -> Press CTRL + D
Now, you can see the ID of each ability (the Ability Name is changed to Spell ID), find the ability and enter it in the parameter using the said function.

Example;

• Set Caster = (Triggering unit)
• Custom script: call UnitMakeAbilityPermanent(udg_Caster, true, 'AHfs')

This will make the Caster to have the Flame Strike (AHfs) ability to permanently stays to that unit.
Usually this problem occurs when the unit faces a morphing stage, in this case, your tower is changing to a new unit via upgrade.

The ID you are looking for, is the Spell Book ability.
If only the Spell Book retains while the spell inside is lost, you have to make for the abilities' ID inside the book too.

NOTE: And yeah, it is CASE-SENSITIVE, remember to put the ' ' encloses the Ability ID.

A better way is just making an identical copy of the spellbook to be put on the alternate unit.
The thing is that when a unit is remade for whatever reason(morph/upgrade), then the game doesn't check for the abilities inside the spellbook.
Thus, it just looks "Alright, the new unit has this ability, so no need to add it".
The result is that the spellbook ability itself is kept, but not the ones inside it.
(My spellbook tutorial also brings out this detail)

Just to be save for preservation (cooldown, etc), it's better to just use the function.

You're saying that instead of simply doing stuff right in the object editor it would be better to use a trigger and 2-12 lines of custom code.
You sure about the cooldowns?

Jup that solved it.
Thanks you guys!
well i didn't had cool-downs so the choice was easy, just created identical copies of the spell book.
that solved the problem. oh and yes the entire spell book was gone and not just the spells inside the book. but nvm its fixed now

Didn't know UnitMakeAbilityPermanent(whichUnit, whichBoolean, whichId) seems like 12 lines of codes to you, either way, it's solved.

You'd have to do this for every ability and additionally also add a line if done in GUI, in order to set the unit variable in a reasonable way.
