[1.19.2] Check if entity is a boss?

[Adil Yilan]

Is there a way to easily determine whether certain entity is a boss?

By boss I mean it has health bar, advanced mechanics, more HP and attack power, etc - but mostly health bar.

I have compared Ender Dragon, Wither and Warden (although I don't know if it is considered a boss), but can't find any property/method that indicates boss status.

Any tips on this would be appreciated.

The health bar at the top of the screen is handled via a ServerBossEvent in the Entity class but unfortunately there is no way to check if a Entity has one or not.

What did you try to achieve? why do you need to know if an Entity is a Boss?

Depending on your own opinion, the following entities can be considered bosses:
Ender Dragon, Wither, Elder Guardian and Warden

@Luis_ST I am making some enchantments which should work on players and regular mobs, but not on boss type of mobs as it would make fights oversimplified.

Some enchantments are percent based, like bleed, so applying it to boss would cut a huge proportion of boss's health.

So basically it is manual work - check if entity is instance of entity classes that should be immune to enchant and that's it?

Unfortunately yes, if you wish to have an easy way to check this feel free to make a PR to Forge.

I think a custom EntityType Tag would be find for that.
