Trigger Help

In my game, when a creep dies, it drops a book and when hero reads it, he learns the spell.

How do i make it so when the Hero reads another book, with different spell, that he learns that one and the other one before is removed?

Well, you could drop custom tomes on the ground and then use the rawcodes of the tomes on the ground to check which book it is in order to level the appropriate ability for the hero.

Or you could simply use GUI and check wether the item that has been picked up by a hero is equal to the type of the custom tomes.

Either ways, it should be really simple. Do you want an example?

Check out this example map:

Note that the ts wanted to remove the previously learned spell. The old spell gets replaced by the new spell.

            • Item - Remove (Item being manipulated)
            • Game - Display to Player Group - Player 1 (Red) the text: true
            • Skip remaining actions
          • Else - Actions
            • Game - Display to Player Group - Player 1 (Red) the text: false

This will only ork for single unit, if to units are trying to use the system, then it will fail.

Use Bribe's unit indexer (search spell database) if you want it to work for multiple units, and make the ability variable an array.
Set ability[Custom value of triggering unit] = ...
Unit - Remove ability[Custom value of triggering unit] from unit
and it will work then.

Ok now here is the thing, In my game, i have books and you have to use/read the book before learning the spell, like you pick up the book and you have to use it. then you learn one spell, and then the next book you read you learn another and remove the previously learnt one.

then just use replace Unit - A unit Acquires an item to Unit - A unit Uses an item, coz maker example seems ok
