Newb friendly error x.x conversion float to int

Question

Assets/_Scripts/_Player/PlayerLevel.cs(33,18): error CS0266: Cannot implicitly convert type double' to int'. An explicit conversion exists (are you missing a cast?) i couldnt find a problem relative enough to mine in forums for me to fix t$$anonymous$$s myself please help

 using UnityEngine;
 using System.Collections;
 
 public class PlayerLevel : MonoBehaviour {
     
     private int curLevel = 1;
     private int maxlevel;
     
     public int curExp = 99;
     private int maxExp = 100;
     
     public float expBarLength;
     
     private int PlayerHealth;
     
     private bool LevelUp = false;
     
     void Start () 
     {
     expBarLength = Screen.width / 2;
     }
     void Update () 
     {
     PlayerHealth playerHealth = gameObject.GetComponent<PlayerHealth>();
     AdjustCurrentExp (0);
         
     if(curExp >= maxExp)
         {
     curExp = 1;
     curLevel++;
     maxExp += (20 * curLevel);
     LevelUp=true;
     playerHealth.endurance += (0.5 * curLevel);
         }
     }
     void OnGUI()
     {
         GUI.Box(new Rect(20, 50, expBarLength, 20), curExp + " / " + maxExp);
         GUI.Box(new Rect(20, 20, 80, 20), "Level: " + curLevel);
     }
     public void AdjustCurrentExp(int adjExp)
     {
         curExp  += adjExp;
         
         expBarLength = (Screen.width / 3 * curExp / (float)maxExp);
     }
 }

T$$anonymous$$s happens because when you write the number

 0.5 // or any other number of the form 'digits.digits'

the type of the number defaults to 'double'. If you instead want it to be treated as a float, you should use

 0.5f;

t$$anonymous$$s will make it a float literal instead of a double. Of course, t$$anonymous$$s isn't neccesarily the problem- I need to know what type 'PlayerHealth.endurance' is.

Looking through your code, I can see several serious issues with it. For starters, you seem to have a type "PlayerHealth"- I assume that t$$anonymous$$s is a different MonoBehaviour script on your object. However, you also have a member "PlayerHealth", w$$anonymous$$ch is an integer!! T$$anonymous$$s will cause serious confusion in your code, and you need to make sure that every name and token you use is unique (for exactly t$$anonymous$$s reason).

Should be 0.5f, not 0.5. Although then you'd have to cast to int; you'd be better off just doing playerHealth.endurance += curLevel / 2;
