How do i get rid of the billboard health GUI?

Im making a hunger games map and I want the billboard health GUI to be hidden.

The currently available options for hiding the health bar above a player are:

1. Set the Player's Head Transparency to 1 (You'll need to make a duplicate head if you still want players to have a head!)

2. Make a custom character (i.e. not the default ROBLOX player) (This is quite complicated, I'd advise using (1) instead, works for most people)

Roblox created a method for this purpose:

game.StarterGui:SetCoreGuiEnabled("Health", false)

Run that in a localscript to disable the Health GUI for the player that the localscript is ran in. If you want to enable it again then just run this:

game.StarterGui:SetCoreGuiEnabled("Health", true)

I hope this helps.
