Description

A prefab that shows a character's health.

Demo

How to use

1. Drag the prefab into the Hierarchy.

2. Make sure an EventSystem exists in the Hierarchy. (If not, you can create one by creating a canvas element then delete it)

3. Set health

public float maxHealth;
public float currentHealth;

public HealthBar healthBar;

private void Start() {
    healthBar.SetMaxHealth(maxHealth);
    healthBar.SetCurrentHealth(currentHealth);
}

4. Update current health when damaged or healed

currentHealth -= damage;
healthBar.SetCurrentHealth(currentHealth);
