Can you fix my level up system?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class LevelUp : MonoBehaviour {
5. int LevelyUp = 0
6.     void OnClick(gameObject) {
7.         int LevelyUp = +1
8.     }
9. }

Help!
I am only a beginner developer. I only know a bit of C#. I want the int LevelyUp when someone clicks a GameObject to increase by 1.

And there are some errors:
Assets/LevelUp.cs(6,12): error CS1519: Unexpected symbol `void' in class, struct, or interface member declaration

Assets/LevelUp.cs(6,22): error CS1041: Identifier expected

Assets/LevelUp.cs(8,9): error CS1525: Unexpected symbol `}', expecting `)', `,', or `;'

Assets/LevelUp.cs(9,1): error CS8025: Parsing error

 

You are declaring a new variable LevelyUp every time the function OnClick is called
Replace

Code (CSharp):

1. int LevelyUp = +1

With

Code (CSharp):

1. LevelyUp++;

Also your code is missing semicolons everywhere, that is why you get those errors. At the end of a line always put ;.

 

Complete fixed code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class LevelUp : MonoBehaviour {
4. int LevelyUp = 0;
5.     void OnClick(GameObject a) {
6.         LevelyUp++;
7.     }
8. }

How much beginner are you?
I'm also assuming you are calling OnClick from elsewhere, but I doubt it.

 

I'd recommend learning C# before diving in to creating game systems. Check out the following for a great, easy-to-follow introduction:

Thanks @Mich_9 !

 

I'm also mostly beginner. I know some script things, like int and void, etc.
