Show and hide serialized class fields based on enum values?

Hi

I was thinking about a way to remove clutter from inspector view of a class that is sort of class containing data for multiple item types to avoid inspector serialization issues if I were trying to use sub classes instead.

Say I have a class similar to one shown below and then a List<Item> of there:

Code (CSharp):

1. [System.Serializable]
2. public class Item
3. {
4.     // enum to set item type
5.     public ItemType itemType;
6.  
7.     // weapon
8.     public int damage;
9.     // more fields for weapon
10.     // ...
11.  
12.     // food
13.     public int foodPoints;
14.     // more food fields
15.     // ...
16.  
17.     // armor
18.     public int armorPoints;
19.     // more armor fields
20.     // ...
21. }
22.  

And I would need to render each list element with custom property drawer I guess.

So could I be able to somehow only show weapon fields if I've set itemType enum to weapon?

I remember having issues with item height as showing a different set of fields will change the height of that item in list.

I have used serialized objects and serialized properties a little bit, but don't remember if this was doable or not.

Any ideas / help?

 

I'll answer this one myself.

I came to conclusion that I'll either have to:

Show fields manually based on itemType selection.

If I selected/set enum to Weapon type, I draw each weapon field manually.... and so on. To make this work in lists, I found some good threads, how to fix list to work with different heights for each list element:

https://answers.unity.com/questions/528274/variable-property-drawer-height-effects-all-in-lis.html

Another way is to render each part so that Item class has fields (Weapon, Pickup) that are depicting each item subtype. Then I can use serialized property to draw that class, using EditorGUILayout.PropertyField and its option includeChildren.

But anyway, if there is some better way to do this I'm all ears.
