Hi. I'd searched THIS in others tickets, but not found, so I post here:
I propose to implement possibility setting of max health(numbers of hearts) for players and eventually for other entities. But especially for players.
By this, I mean procedures like a "get entity maxHealth" and "set enity maxHealth". And this without unessesary use HealthBoost potion effect.
This can be a useful for creating more RPG style mods and more difficut style game ex. player start with two hearts(4 hp) or can just lose max HP for some punish.
Also if player beat some boss, then next time this boss can spawn with more healt points, etc.
This suggestion might applies for other entity's atributies like maxDamage, etc.
