Disabled Spellbook Problem

[Koba10s]

• So I created a Disabled Spellbook and added just one spell to it: Dark Orb ability (Bonus attack, posibility to attack flying targets from distance and summoning skeletons by killing a unit)

• Then I addad Spellbook to sample hero.

• Everything seems to work fine -> Icon is hidden, bonus attack is applied, hero is able to attack flying creatues but summoning skeletons by killing a unit doesn't work at all.

Can someone explain me why? It is just one ability, why some effects of it works and other don't?
Is there any way to get it right?

Make sure that the attacked target can create skeletons (can be raised).

Apart from that you should no longer use disabled spell books to hide abilities. It is more likely to cause bugs.
You can now simply hide any ability by setting the buttons position to (0, -11).

instead of disabiling a spellbook try putting it at 0, -11 for some reason this makes it so it doesn't show up in the gui

Editor does not allow me to put -11 into Button Position (Y). I enabled the option to accept negative values. What should I do?

 

[millzy]

shift click to put in negatives

Aight it works. Thank you guys.
Also does it work for more than one ability? For example if I will give X abilities to a unit, all with position 0, -11 they all gonna be invisible?

In the editor go to file on the toolbar, then click on preferences all the way on the bottom of the dropdown menu, select the general tab and click "allow negative real values in the object editor"
