Spell Question!?

ok i saw this in a custom game before.....

i wanted to make an rpg completely customizable but i was having a hard time with the spell system. I did not want to limit each character to their 5 spells i choose! Instead i wanted to make "Schools of Magic" where a caster could go and train in spells using wood or gold! But! i dont know how to make it so you can buy a spell! i have tried creating triggers where when you buy an item it removes it and "adds spell to hero" but it never works and item just becomes spell. Does anyone know this trick? I tried to open a rpg i found but it was protected :( and in german so i couldnt email guy asking how. Thanks in advance :)

huh?
add ability to unit didnt work? you must have made something wrong...

try this, if it doesnt work i dunno

E:a Unit aquires an item

C:Item type of item beeign manipulated equal to(item type)


A:
Item- remove (item beeign manipulated)
Unit-Add (ability) to (hero manipulating item)

He wants to add an ability as a Hero ability, which you can't. The Add Ability trigger only adds things as unit abilities.

I'll move you to the appropriate forum.
