please help error

i get this error when i try playing my game
NullReferenceException: Object reference not set to an instance of an object
Click.Update () (at Assets/Scripts/Click.cs:13)
here is my script it's c#\

using UnityEngine;
using System.Collections;

public class Click : MonoBehaviour {

public UnityEngine.UI.Text fpc;
public UnityEngine.UI.Text fatDisplay;
public float fat = 0.00f;
public int fatperclick = 1;

void Update () {
fatDisplay.text = "Fat: " + fat;
fpc.text = "FPC: " + fatperclick;
}

public void Clicked(){
fat += fatperclick;
}

}

 

You should double check your fpc and fatDisplay elements in the inspector, they may not be assigned.

 

what do you mean??

 

I'm new how do i do that?

 

When you define public variables, they show up in the Unity Editor on the component in the Inspector. You need to drag and drop the appropriate objects into the component fields for the component to use them, or click the little circle next to them and choose from the list.

You have two public Text fields, so your "Click" component will have two "Text" fields that start out empty.

 

i don't get it im sorry if im giving you trouble

 

When you add the Click component to an object, you will see this. See those two fields that say "none"? You need to drag into those fields the corresponding UI Text objects that you're trying to use.

 

ok let me try it

 

here what i get i have no text take a look

 

help

 

Assets/Scripts/Click.cs(8,22): error CS0102: The type `Click' already contains a definition for `fat'
now i got this error

 

here is my screen now but i got this other error i did what you said

 

Make sure that all the Click components in the scene have their fields assigned correctly.

 

now i have a erro with line 12 pls halp ;(

 

i followed this tutorial

 

if you could point anything i did wrong could you tell me?

 

and if you have youtube i could subscribe to you

 

here is my script


using UnityEngine;
using System.Collections;

public class Click : MonoBehaviour {

public UnityEngine.UI.Text fes;
public UnityEngine.UI.Text fatDisplay;
public float fat = 0.00f;
public int fatperclick = 1;

void Update () {
fatDisplay.text = "Fat: " + fat;
fes.text = "FES: " + fatperclick;
}

public void Clicked(){
fat += fatperclick;
}

}

 

You need to check that none of your fields say "None". They all need to have objects assigned. That's how to fix this.

 

i changed some of the names

 

i did it still problems

 

using UnityEngine;
using System.Collections;

public class Click : MonoBehaviour {

public UnityEngine.UI.Text fes;
public UnityEngine.UI.Text fatDisplay;
public float fat = 0.00f;
public int fatperclick = 1;

void Update () {
fatDisplay.text = "Fat: " + fat;
fes.text = "FES: " + fatperclick;
}

public void Clicked(){
fat += fatperclick;
}

}
