I uploaded the levelLoader file to the gameobject. Still, when I drag the script file onClick Event, the no function is null. Why? Can anybody help me?

No Function

C# code:

using UnityEngine;
using System.Collections;

public class LevelLoader : MonoBehaviour {

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame


    public void LoadLevel(int a)
    {

        Application.LoadLevel(a);
    }

    public void Quit()
    {

        Application.Quit();
    }
}

Correct me where I am wrong. I am following this racing car game tutorial. At 7:58 he added this event. Please help me!!!

  • \$\begingroup\$ You musn't drag & drop the script itself, but the object holding the script. To do so, create a new Empty gameobject in your scene, and drag & drop the file (from Project tab) to the empty game object in the Hierarchy tab. \$\endgroup\$

You need to add the LevelLoader script to the LevelLoader object in the hierarchy panel. Then drag the entire LevelLoader object (not script) from the hierarchy panel to the OnClick selected object.
