How do you check a player's health?

I have recently been trying to make a custom UI, any idea on how I could check a player’s health and put it on ui?

The health information is in the healthful interface which is part of fort_character. Assuming you have an agent or player you should be able to get the health by doing this:

if (FortCharacter := MyAgent.GetFortCharacter[]):
    FortCharacter.GetHealth()

Don’t forget to include “using { /Fortnite.com/Game }” to get access to the healthful interface
