Custom Editor and Drawer issues.

I'm having a lot of confusion over custom property drawers. I've tried many combinations of ideas but nothing has really worked out. A little conceptual guidance would really help. If I understand what it is I'm supposed to implement, I can do the scripting myself.

To describe this as simply as possible, I have a Spell class and a SpellEffect class (or struct; whichever is necessary). The Spell class contains List<SpellEffect>. The SpellEffect class contains several variables (let's say a bool, a float, and a string).

I want to make a custom editor for the Spell class. In the editor, I want to show the list of SpellEffects, and have each SpellEffect's bool and string be editable.

Where do I start?

 

CustomPropertyDrawer for the spelleffect alone should suffice, as long as spelleffect is serialisable

The example there pretty much covers your situation, class with a few properties

Shouldnt need a custom editor for the Spell class
