need help converting JS to C

Questions & Answers
1

I just purchased a script from online and i didn’t realize it was in JS. Any one willing to translate this for me into C#? I’ve tried but keep on failing :frowning:

var Point : float;
private var GetHitEffect : float;
public var targY : float;
private var PointPosition : Vector3;

var PointSkin : GUISkin;
var PointSkinShadow : GUISkin;

function Start() {
 Point = Mathf.Round(Random.Range(Point/2,Point*2));
 PointPosition = transform.position + Vector3(Random.Range(-1,1),0,Random.Range(-1,1));
 targY = Screen.height /2;
}

function OnGUI() {
 var screenPos2 : Vector3 = Camera.main.camera.WorldToScreenPoint (PointPosition);
 GetHitEffect += Time.deltaTime*30;
 GUI.color = new Color (1.0f,1.0f,1.0f,1.0f - (GetHitEffect - 50) / 7);
 GUI.skin = PointSkinShadow;
 GUI.Label (Rect (screenPos2.x+8 , targY-2, 80, 70), "+" + Point.ToString());
 GUI.skin = PointSkin;
 GUI.Label (Rect (screenPos2.x+10 , targY, 120, 120), "+" + Point.ToString());
}

function Update() {
 targY -= Time.deltaTime*200;
}

using UnityEngine;
public class SomeClass : MonoBehaviour
{
    public float Point;
    private float GetHitEffect;
    public float targY;
    private Vector3 PointPosition;

    public GUISkin PointSkin;
    public GUISkin PointSkinShadow;

    void Start()
    {
        Point = Mathf.Round(Random.Range(Point / 2, Point * 2));
        PointPosition = transform.position + new Vector3(Random.Range(-1, 1), 0, Random.Range(-1, 1));
        targY = Screen.height / 2;
    }
    void OnGUI()
    {
        Vector3 screenPos2 = Camera.main.camera.WorldToScreenPoint(PointPosition);
        GetHitEffect += Time.deltaTime * 30;
        GUI.color = new Color(1.0f, 1.0f, 1.0f, 1.0f - (GetHitEffect - 50) / 7);
        GUI.skin = PointSkinShadow;
        GUI.Label(new Rect(screenPos2.x + 8, targY - 2, 80, 70), "+" + Point.ToString());
        GUI.skin = PointSkin;
        GUI.Label(new Rect(screenPos2.x + 10, targY, 120, 120), "+" + Point.ToString());
    }
    void Update()
    {
        targY -= Time.deltaTime * 200;
    }

Basically, in C# you needed to place a new keyword before struct creators like Vector3(…) and Rect(…):

public float Point;
private float GetHitEffect;
public float targY;
private Vector3 PointPosition;

public GUISkin PointSkin;
public GUISkin PointSkinShadow ;

void Start() {
 Point = Mathf.Round(Random.Range(Point/2,Point*2));
 // C# requires the "new" keyword before any structure
 PointPosition = transform.position + new Vector3(Random.Range(-1,1),0,Random.Range(-1,1));
 targY = Screen.height /2;
}

void OnGUI() {
 // Camera.main IS a camera reference! No need for .camera
 Vector3 screenPos2 = Camera.main.WorldToScreenPoint (PointPosition);
 // this instruction makes no sense in OnGUI!
 // maybe it should be moved to Update
 GetHitEffect += Time.deltaTime*30;
 GUI.color = new Color (1.0f,1.0f,1.0f,1.0f - (GetHitEffect - 50) / 7);
 GUI.skin = PointSkinShadow;
 // Rect also needs a "new" keyword in C#
 GUI.Label (new Rect (screenPos2.x+8 , targY-2, 80, 70), "+" + Point.ToString());
 GUI.skin = PointSkin;
 GUI.Label (new Rect (screenPos2.x+10 , targY, 120, 120), "+" + Point.ToString());
}

void Update() {
 targY -= Time.deltaTime*200;
}

NOTE: As said in the comments, there’s a weird instruction in OnGUI that adds Time.deltaTime*30 to GetHitEffect - this makes no sense, and will increase GetHitEffect in an unpredictable speed because OnGUI is called 2 to 4 times between frames. Maybe moving this instruction in Update could at least make it work predictably.
