How can i show number of lives as image during gameplay

Questions & Answers

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

[26980-prova+ui±+copia.png|26980]

I added the first life, and this 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 him automatically wrapped the x position of the texture “middle”?

It’s possible do this white 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 this thing, I’m a beginner and this is the only way that came to my mind.

Right now I’m using this 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(740.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);

		GUI.DrawTexture (new Rect(560.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);
	}
	if (life == 6)
	{
		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(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);
		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);
		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);
		GUI.DrawTexture (new Rect(440.0f,-75.0f,100.0f,200.0f), middle,ScaleMode.ScaleToFit,true,0);		
	}

}

Thanks in advice!

Have you tried looking at while 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);
while(i < life)
{
		GUI.DrawTexture (new Rect(800.0f - 60 * (i - 1),-75.0f,100.0f,200.0f), Middle,ScaleMode.ScaleToFit,true,0);
		i++;
}

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