Implementing the gizmo grid

When you open the script Level.cs. You will see the following code:

using UnityEngine;

namespace RunAndJump {
  public partial class Level : MonoBehaviour {

    [SerializeField]
    public int _totalTime = 60;
    [SerializeField]
    private float gravity = -30;
    [SerializeField]
    private AudioClip bgm;
    [SerializeField]
    private Sprite background;

    public int TotalTime {
      get { return _totalTime; }
      set { _totalTime = value; }
    }

    public float Gravity {
      get { return gravity; }
      set { gravity = value; }
    }

    public AudioClip Bgm {
      get { return bgm; }
      set { bgm = value; }
    }

    public Sprite Background {
      get { return background; }
      set { background = value; }
    }
   }
}

This script holds the variables that you saw in the inspector and the properties to access and change these values.

Note

As you may have noticed, making your variables public is not the only way to expose them in the...
