How can I change this script to use GUITexture instead of GUI number, for health display?
Goal is to make so that health gets subtracted, and results in new GUItexture every 5% of health drop(as a health bar), but currently, I have a number GUI set up. OR if a scaling bar is more optimized, I may do that.
@script ExecuteInEditMode()
var hitPoints : int;
var painSound : AudioClip;
var die : AudioClip;
var deadReplacement : Transform;
var mySkin : GUISkin;
var explShake : GameObject;
private var radar : GameObject;
private var maxHitPoints : int;
var damageTexture : Texture;
private var time : float = 0.0;
private var alpha : float;
private var callFunction : boolean = false;
function Start(){
maxHitPoints = hitPoints;
alpha = 0;
}
function Update(){
if (time > 0){
time -= Time.deltaTime;
}
alpha = time;
}
function PlayerDamage (damage : int) {
if (hitPoints < 0.0)
return;
// Apply damage
hitPoints -= damage;
audio.PlayOneShot(painSound, 1.0 / audio.volume);
time = 2.0;
function OnGUI () {
GUI.skin = mySkin;
GUI.contentColor = Color.red;
GUI.Label (Rect(40, Screen.height - 50,60,60)," Health: ");
GUI.Label (Rect(100, Screen.height - 50,60,60),"" +hitPoints);
GUI.color = Color(1.0, 1.0, 1.0, alpha); //Color (r,g,b,a)
GUI.DrawTexture(new Rect(0,0,Screen.width, Screen.height), damageTexture);
I recommend creating an actual GUITexture in your scene instead of using GUI.DrawTexture. You can also store a rectangle for the current health bar instead of making one every OnGUI call (every frame). I would do this for all rectangles in OnGUI.
To update your health bar, I would do the following ...
var MAX_HITPOINTS = 100;
var healthBarOrigWidth : int;
var healthBar : GUITexture;
function PlayerDamage (damage : int) {
//Somewhere in this function
healthBar.width = healthBarOrigWidth * (hitPoints/MAX_HITPOINTS);
}
This way you don't create rectangles every frame in the OnGUI function. The health bar updates when PlayerDamage() is called.
I am getting this error: $$anonymous$$issingFieldException: Field 'UnityEngine.GUITexture.width' not found
Generally, you can figure out your problem when it is as simple as a variable/property not found.
http://docs.unity3d.com/Documentation/ScriptReference/GUITexture.html
So you can check on the documentation of GUITexture and see if it exists. In our case, it doesn't. It is inside pixelInset. So basically, someGuiTexture.pixelInset.width.
Hope this helps.
