How can i show number of lives as image during gameplay

Question

I would like to show the lives as in the following image

alt text

I added the first life, and t$$anonymous$$s is the script that I did:

public class GuiLife : MonoBehaviour {

public Texture middle;

public Texture Base;

public GameObject player;

 private playerLife lifeScript;
 private int life;
 private int n;

 void Start () 
 {
     lifeScript = player.GetComponent ("playerLife") as playerLife;
     life = lifeScript.vita;
     n = life - 1;
 }
 
 void OnGUI()
 {
     if (life == 1)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
     }

     if (life > 1)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
         for (int i = 0, i < n , i++)
         {

         }
     }

 }

}

I wanted to check inside for how many lives I n times and add the texture to life, but the question is how do I tell $$anonymous$$m automatically wrapped the x position of the texture "middle"?

It's possible do t$$anonymous$$s w$$anonymous$$te the FOR or i need to place the textures for each case?

It is very likely that there is a much more efficient way to do t$$anonymous$$s t$$anonymous$$ng, I'm a beginner and t$$anonymous$$s is the only way that came to my mind.

Right now I'm using t$$anonymous$$s bad script.

void Start () { lifeScript = player.GetComponent ("playerLife") as playerLife; n = life - 1;

 }

 void Update ()
 {
     life = lifeScript.vita;
 }
 
 void OnGUI()
 {
     if (life == 1)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
     }

     if (life == 2)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(740.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
     }

     if (life == 3)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(740.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(680.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
     }
     if (life == 4)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(740.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(680.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(620.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
     }
     if (life == 5)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);

         GUI.DrawTexture (new Rect(560.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
         GUI.DrawTexture (new Rect(500.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
     }
     if (life == 7)
     {
         GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);

 }

Thanks in advice!

Have you tried looking at w$$anonymous$$le loops used with an iteration integer i?

 int i = 1;    //we're starting at 1 here because you draw a different texture for only one life, usually i starts at 0
 GUI.DrawTexture (new Rect(800.0f,-75.0f,100.0f,200.0f), Base,ScaleMode.ScaleToFit,true,0);
 w$$anonymous$$le(i < life)
 {
         GUI.DrawTexture (new Rect(800.0f - 60 * (i - 1),-75.0f,100.0f,200.0f), Middle,ScaleMode.ScaleToFit,true,0);
         i++;
 }

T$$anonymous$$s type of loop comes in very handy in many situations, so getting familiar with it should help you further down the road, too.

@christoph_r thanks for the help, but i have another problem, do you know how i can resize dynamicly with screen resolution? because doing so changes everything from phone to phone.

That is a bit difficult in Unity, what you might want to look at is GUIUtility.ScaleAroundPivot.
