A little help "translating" from JS to C#

Scripting C# & .NET
1

Hey guys…

I wonder if anyone could help me writing this in C#, instead of Java…
It is wokring fine in Unity, but when I try to compile it for the Metro Store, it gives me an error so I want to have it in C# so I can have everything under the same folder.

This is the JS script:

var hp : float;
var maxHP : float;
var healthBarWidth : int;
var myHealthBar : GameObject;
var myhb : GameObject;
var health : BossCB;

function Awake(){
    health = this.GetComponent("BossCB");
}


function Start () {
    healthBarWidth = 20;
    myhb=Instantiate(myHealthBar,transform.position, transform.rotation);
    maxHP = 300;
    hp = maxHP;
}

function Update () {
    myhb.transform.position = Camera.main.WorldToViewportPoint (transform.position);
    myhb.transform.position.x -= .05;
    myhb.transform.position.y -= .05;
    myhb.transform.localScale=Vector3.zero;

    hp = health._healths;

    var healthPercent : float = hp/maxHP;
    if(healthPercent<0){healthPercent=0;}
    if(healthPercent>100){healthPercent=100;}
    healthBarWidth=healthPercent*20;
    myhb.guiTexture.pixelInset=Rect(10,10,healthBarWidth,5);
}

Thanks!!

I have been translating some and I have this, so far:

using UnityEngine;
using System.Collections;

public class PlanetBossHealthBarC : MonoBehaviour {

    public float hp;
    public float maxHP;
    public int healthBarWidth;
    public GameObject myHealthBar;
    public GameObject myhb;
    private PlanetBoosCB health;

    public bool hbCreation=true;

    void Awake()
    {
        health = GetComponent<PlanetBoosCB>();
    }

    void Start()
    {
        healthBarWidth = 20;
        myhb = Instantiate(myHealthBar, transform.position, transform.rotation)as GameObject;
        maxHP = 3000;
        hp = maxHP;
    }

    void Update()
    {
             hp = health._healths;

        float healthPercent  = hp/maxHP;
        if(healthPercent<0){healthPercent=0;}
        if(healthPercent>100){healthPercent=100;}
        healthBarWidth=(int)healthPercent*20;
        myHealthBar.guiTexture.pixelInset = new Rect(50, 50, healthBarWidth, 5);
    }
}

So what I am missing is:

myhb.transform.position = Camera.main.WorldToViewportPoint (transform.position);
    myhb.transform.position.x -= .05;
    myhb.transform.position.y -= .05;
    myhb.transform.localScale=Vector3.zero;

The health bar suppose to appear in the middle of its parent… but there´s nothing showing up yet

Any ideas?

Your transform.localScale is set to 0, try setting it to 1 and see if that fixes it.

Having this

using UnityEngine;
using System.Collections;

public class PlanetBossHealthBarC : MonoBehaviour {

    public float hp;
    public float maxHP;
    public float healthBarWidth;
    public GameObject myHealthBar;
    public GameObject myhb;
    private PlanetBoosCB health;

    public bool hbCreation=true;

    void Awake()
    {
        health = GetComponent<PlanetBoosCB>();
    }

    void Start()
    {
        healthBarWidth = 20;
        myhb = Instantiate(myHealthBar, transform.position, transform.rotation)as GameObject;
        maxHP = 3000;
        hp = maxHP;
    }

    void Update()
    {

        myhb.transform.position = Camera.main.WorldToViewportPoint(transform.position);
//        myhb.transform.position.x -= .05;
//        myhb.transform.position.y -= .05;
        myhb.transform.localScale = Vector3.zero;
       

        hp = health._healths;

        float healthPercent  = hp/maxHP;
        if(healthPercent<0){healthPercent=0;}
        if(healthPercent>100){healthPercent=100;}
        healthBarWidth=healthPercent*20;
        myHealthBar.guiTexture.pixelInset = new Rect(50, 50, healthBarWidth, 5);
    }
}

I have the little bar a little bit to the side of its parent… but it is not decreasing while its parent gets hit (as it suppose to happen)

I have been debugging… and I found:
Everything is decreasing each time the parent gets hit, which is right: hp, healthBarWidth and healthPercent.

However:
a) The bar does not change dinamically
b) depending on what I debug, I get different bar sizes:
hp = full bar
healthBarWidth = 20
healthPercent = 1

How do I make it work the way it suppose to?

Found it… my bad.
Last line has to be myhb instead of myHealthBar :slight_smile:
