Plugins Plugin Development

i want to show player’s health armor value…somewhere on the screen , can plugin api achieve the work? or i have to combine the both

Chat, Titles, BossBars, Scoreboards, Action Bar, abusing inventory stacks, are all options in vanilla.

The plugin API on it’s own can’t display custom GUI to the player, but you can certainly use the existing GUI in the game to your advantage.

I would recommend using BossBar or Scoreboard to show players armour values using “plugin api”.

BossBar would display the armour value in a Ender Dragon health bar, only you can customise the colour of the bar and the text on the bar. A Scoreboard would show it in a signal column on the right hand side of the players screen, or a number on the tab list depending how you program it.
