help convert js to c#

Unity Engine

Need help to convert Jcsript to C#, if there are some experienced C# proggers pls help, here the script:

var maximumHitPoints = 10.0;
var hitPoints : float = 10.0;
var healthGUI : GUITexture;
var die : AudioClip;
var buttonDown : boolean = false;
var damage : float = 0.0;

private var healthGUIWidth = 0.0;

function Awake () {
   healthGUIWidth = healthGUI.pixelInset.width;
}

function Update() {
 if (Input.GetButton("Fire1"))
 {
  damage = Time.deltaTime;
  ApplyDamage();
 }
 else
 {
   hitPoints += Time.deltaTime*0.5;
 }
hitPoints = Mathf.Clamp(hitPoints, 0, maximumHitPoints);
} 

function LateUpdate () {
   UpdateGUI();
}

function ApplyDamage () {
   hitPoints -= damage;
}

function UpdateGUI () {
   
   var healthFraction = Mathf.Clamp01(hitPoints / maximumHitPoints);
   healthGUI.pixelInset.xMax = healthGUI.pixelInset.xMin + healthGUIWidth * healthFraction;

}

it is not specific code in C#.However , there are some differences between defines functions and variables.

For example, in Jscript you define functions as “function Update or function OnGUI” . C# script , you define functions as “void Update or void OnGUI”.Moreover, for variable definitions in jscript, you define the variables as "var a = 5 or var buttonDown : boolean = false ". In C# script you should define the variables as “int a=5 or bool buttonDown=false”.

Here’s my variant:

using UnityEngine;
using System.Collections;

public class powerBar : MonoBehaviour {
public float maximumHitPoints = 10f;
public float hitPoints = 10f;
public GUITexture healthGUI;
public bool buttonDown = false;
public float damage  = 0f;
private float healthGUIWidth = 0f;

	// Use this for initialization
	void Awake () {
		healthGUIWidth = healthGUI.pixelInset.width;
	}

	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetButton("Jump"))
		 {
		  damage = Time.deltaTime;
		 }
			 else
			 {
			   hitPoints += Time.deltaTime*0.5f;
			 }
		hitPoints = Mathf.Clamp(hitPoints, 0f, maximumHitPoints);
	
	}
	
void LateUpdate () {
   UpdateGUI();
}

void ApplyDamage () {
   hitPoints -= damage;
}

void UpdateGUI () {
   
   float healthFraction = Mathf.Clamp01(hitPoints / maximumHitPoints);
   healthGUI.pixelInset.xMax = healthGUI.pixelInset.xMin + healthGUIWidth * healthFraction;

}
	
}

But i’ve got this error:

Assets/Scripts/powerBar.cs(46,14): error CS1612: Cannot modify the return value of `UnityEngine.GUITexture.pixelInset’ because it is not a variable

Does it mean that i should declare pixelInset in C# as a variable?

No… something in C# gets funny with structs and multi-level assignments. I think you need something along the lines of…

var tempInset = pixelInset;
tempInset.xMax = 2; //put your calculations here
healthGUI.pixelInset = tempInset;

i’ve found smth like this:

void UpdateGUI () {
	   	float healthFraction = Mathf.Clamp01(hitPoints / maximumHitPoints);
		Rect pos = healthGUI.pixelInset;
		pos.xMax = healthGUI.pixelInset.xMin + healthGUIWidth * healthFraction;
		healthGUI.pixelInset = pos;
	}
}
