Button should change his texture seven times by clicking it

Hey guys
can somebody pls help me? I tryed for 3 hours to find or to creat a solution but I failed (C#).
I tryed to creat this:



Thanks for your help.

 

What have you tried so far?

 

public class TexChanger : MonoBehaviour {

int a; // a = Count from 1 to 7

public void Button_Click() {
if(Input.GetButtonDown(a + 1)
Debug.Log(a);

if(a==1) {
renderer.material.mainTexture1
}
if (a == 2)
{
renderer.material.mainTexture2
}
if (a == 3)
{
renderer.material.mainTexture3
}
if (a == 4)
{
renderer.material.mainTexture4
}
if (a == 5)
{
renderer.material.mainTexture5
}
if (a == 6)
{
renderer.material.mainTexture6
}
if (a == 7)
{
renderer.material.mainTexture7
}

return;
}

 

You're not assigning "a" anywhere.

 

if your Button_Click() is connected to the OnClick event of the button in the inspector, that part is correct. If not, that's what you should do.
You should remove "If(Input.GetButtonDown(a+1))" - just get rid of that.
And then, as the previous poster said. Make sure you begin by assigning a value to 'a'.. and don't forget to put keep it within your desired range.

 

I don't get it I'm a beginner and it's very complicated for me :'(

using UnityEngine;
using System.Collections;

public class RundenzahlerTexWechler : MonoBehaviour {

int a = counter;
public a = 1;

///count the number of click
counter++;

if (a == 1)
renderer.material.mainTexture1;

if (a == 2)
renderer.material.mainTexture2;

if (a == 3)
renderer.material.mainTexture3;

if (a == 4)
renderer.material.mainTexture4;

if (a == 5)
renderer.material.mainTexture5;

if (a == 6)
renderer.material.mainTexture6;

if (a == 7)
renderer.material.mainTexture7;

if (counter > 7)
return;

}

 

If you're that new, you'd likely benefit from some introductory tutorials for Unity/scripting in Unity.
Check out some on the website.
If this is a UI button, you can just change the sprite (pretty sure you don't need the renderer material).

There are several other issues with your script, but I would just be giving you bits of a tutorial here.

You script doesn't have a function.
your 'a' value isn't declared properly, I figure you meant: public int a = 1;
and 'counter' isn't necessary since it's doing the exact same thing as 'a'.

Please try to start at the beginning. I promise you you'll have a much nicer time.
