GuiTexture Width Change
Hallo i am bigginer at js and i made a js so i can use my damage scripts to reduse the Width of my GuiTexture as i have made it a healthbar. Here is my script but i dont know what's wrong :
var HP : int = 100;
function Start () {
HP = guiTexture.texture.width;
}
function Update () {
transform.width (HP);
}
I would also want to make my player change location to 0.0.0 if HP or width is <= 0
That's totally wrong: you must get the GUITexture initial width from guiTexture.pixelInset.width and save it, then multiply by HP/100 and set it back at Update. But this script should be attached to the GUITexture object, which cannot be childed to the player! . Since the health bar can't be a child of the player, modifying the HP variable and respawn the player will be a bit tricky. A better alternative is to attach the health script to the player and use a reference to the GUITexture instead of the property guiTexture, like this:
Player health script:
// drag the GUITexture from the Hierarchy view to this field in the Inspector: var healthBar: GUITexture; var HP : int = 100; var lives: int = 3; // lives available var respawnPoint = Vector3.zero; // respawn position
private var width100: float; // the initial healthBar width
function Start () { width100 = healthBar.pixelInset.width; }
function Update () { // set the health bar width: healthBar.pixelInset.width = width100 * HP / 100; if (HP <= 0){ // player has died? if (lives > 0){ // if there are more lives... lives--; // decrement lives... HP = 100; // restore HP... transform.position = respawnPoint; // move to respawn point } else { // sorry, no more lives - game over! Application.Quit(); } } }
// function that applies the damage: function ApplyDamage(damage: float){ HP -= damage; } In the other script, you can apply damage in the collision event like this:
function OnCollisionEnter(col: Collision){
col.transform.SendMessage("ApplyDamage", 5, SendMessageOptions.DontRequireReceiver);
}
You made me understand and i made my own health script based on your script, thnx dude !
so now i got an other problem i made 2 scripts one for Health and one for damage so in the first script i made a
Public var HealthPoints : int = 100;
and in the damage one i did this : var HealthDamage : int = 5;
function OnCollisionEnter ()
{
HealthPoints : -= "HealthDamage";
}
It would be better to have a specific ApplyDamage function in the health script above, and call it explicitly or via Send$$anonymous$$essage in the collision event - take a look at my answer: I edited it to include the damage stuff.
