// Update is called once per frame
void Update()

}
private void OutputHealth()

CalculateAndOuputHealth(); // you can add a run condition
}
private void CalculateAndOuputHealth()
{
myText.text = "";
currentHealth = player.DisplayHealth();
healthBarDisplay = Mathf.RoundToInt((currentHealth / playerMaxHealth) * maxBars) ;
for(int i = 0; i < healthBarDisplay; i++)
{
myText.text += "|"; // use any character you prefer (in quotes)
}
}
}
And in Player.cs add a function
public int DisplayHealth()
{
return health;
}
I MacGyvered my own health bar code. Tag this script onto a TextMeshPro game object and watch it work its magic. You’ll have to also tweak the spacing between characters on your object to make it work.
