for debugging purpose i’d like to turn on/off enabled and usually i add an empty Update method, wonder if there is another way
The docs are pretty clear about what does and doesn’t show it: Unity - Scripting API: MonoBehaviour
You need a Unity event, period. It it can be any Unity event.
Add an OnEnable() or Start(), which won’t fire every frame unlike Update().
Well that’s… pointless. If there’s no checkbox, the checkbox won’t actually be doing anything if it were there. It only shows when it actually does something.
