equivalent to Button Show IF?

[laurentopia]

I'd like this button to hide away when prefab is filled up. What's the proper syntax?

Hi, use PlayaHideIf for non serialized target:

public GameObject prefab;

[PlayaHideIf(nameof(prefab))]
[Button]
public void CreateSo(){}

Unity_XAKm7H1DRd.mp4

Great, thanks.
Is this possible?

where
public MCPrefab_SO prefab;
and

This is not supported, and has no similar alternative either. You need a helper function:

[PlayaHideIf(yourConditions..., "$" + nameof(HelperFunc))]
[Button]
public void MyFunc() {}

HelperFunc() => prefab.prefab != null;

Why does it need a different attribute for buttons and fields?
It'd be better to have the same.
