Make healthbar size from percentage instead of value.

Question

Hello!

I got this code which determines the size of the health bars in my game.

 float currentHealth;
 float maxHealth;
 
     void OnChangeHealth (float Health)
     {
         healthBar.sizeDelta = new Vector2(Health, healthBar.sizeDelta.y);
     }

When my units get lots of hp the bar becomes ridiculously long. Can someone please tell me how to make the health bar size depend on percentage of remaining health instead?

Thanks in advance!

  float currentHealth;
  float maxHealth;
  float maxSize;
 
      void Start(){
          maxSize = transform.localScale.x
      }
 
      void OnChangeHealth (float health)
      {
          healthBar.sizeDelta = new Vector2(health / maxHealth * maxSize, 
          healthBar.sizeDelta.y);
      }

Basically just make another variable for the standard size of the healthbar when the health is full :)

Thank you!

I got it to work with a few modifications.

I got 1 weird problem. If i do this. The health bar is empty. Debug.log do say maxsize value is 100.

     Start (){
        maxSize = 100;
 
     Debug.Log (maxSize);
 }
     void OnChangeHealth (float Health)
     {
         healthBar.sizeDelta = new Vector2((Health / maxHealth * maxSize), healthBar.sizeDelta.y);
     }

When i do this it works perfectly. I cant figure out why it wont work with a variable ins$$anonymous$$d of a number.

     void OnChangeHealth (float Health)
     {
         healthBar.sizeDelta = new Vector2((Health / maxHealth * 100),

healthBar.sizeDelta.y); }

If using an Image element then...HealthBarImage.fillAmount = currentHealth / maxHealth works the best.
