Question by nyberg98 · May 14, 2020 at 03:59 PM · error player error message damage healthbar

what is wrong here trying to make my player take damage by a projectile

this is the error Assets\HealthBar.cs(30,4): error CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement

this is the code

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class HealthBar : MonoBehaviour { public float health; public Slider slider; public Gradient gradient; public Image fill;
  public void SetMaxHealth(int health)
  {         slider.maxValue = health;
      slider.value = health;
      fill.color = gradient.Evaluate(1f);
  }
  public void SetHealth(int health)     {
      slider.value = health;
      fill.color =
gradient.Evaluate(slider.normalizedValue); } void OnCollisionEnter(Collision obj) { if (obj.gameObject.tag=="Projectile") health - health - 1f; }

}
