Need Help

Hi Im having trouble in making a hero ability multi sectioned spellbook (as in you click the spellbook skill and it brings up 2 other spellbook type things that have things like water magic and fire magic) so I can make a very magic based hero that has ALOT of spells

Also how do you make a kinda overlayed house similar in life as a colonist where its not a seprate section of the map but kinda a multi layered map or something like that thanks in advance

#1 Just have a spellbook and have the abilities inside the firstone be spellbooks that lead to different forms of magic...

#2 You would create the doodad and if its on the second level, change collision size to zero and change the height to x...

erm

#1: I know that much and when I tried and tested it it didnt work

#2: In english plz p.s I mean making a multi layered house w/o having to make a giant map that just teleports u 2 different places as in LoaC

Custom intergers. Set units' custom integers, such as ground floor is 1 and first floor is 2. Then, have conditions for your triggers such as:
Unit casts spell.
Casting unit and target both have same custom integer.
TA-DA!

I thought that out in 10 seconds.
