Main objective of this blog post is to give you an idea about how to Fade an Image into and Out of a Scene in Unity.


This technique can be useful when you want to fade in some text or maybe fade out some falling enemies.


Step 1 Implementation

It's quite easy to implement. Just follow the steps given below.


1.1 Hierarchy Set Up


  • Create a new project and set an environment as shown above.
  • Make two panels:
    1. PanelOne
    2. PanelTwo
  • Each panel should contain one Button.
  • Make two empty game objects and name them as PanelManager and FadeGameobject.
  • Now, make 4 scripts named PanelOne, PanelTwo, PanelManager and Fading.


  • Select one white or black image for applying the effect and set it as below.



1.2 Panel Script

  • Now what we have to do is set a button which when pressed will active and deactivate corresponding panel and fade in-out effect will be executed.


  • Write the code given below in Panel Manager Script.
public class PanelManager : MonoBehaviour {
public GameObject panelOne, panelTwo;
public static PanelManager instance;
void Awake()
instance = this;
  • Write the code given below in Panel One Script.
public class PanelOne : MonoBehaviour {
// Use this for initialization
void OnEnable()
//It will find gameobject which have fading script and call its method.
GameObject.Find("FadeGameObject").GetComponent<Fading>(). BeginFade(-1);
public void onGotoSecondButtonClick()
  • Write the below code in Panel Two Script.
public class PanelTwo : MonoBehaviour {
void OnEnable()
GameObject.Find("FadeGameObject").GetComponent<Fading>(). BeginFade(-1);
public void onGotoFirstButtonClick()
  • Now, what we actually have to do is just active and deactivate the panel.

1.3 Fading Script

  • In fading script write the code given below.
public class Fading : MonoBehaviour
public Texture2D fadeOutTexture; // the texture which you want to overlay to the screen
public float fadeSpeed = 0.8f;
private int drawDepth = -1000; // Low number will render on top
private float alpha = 1.0f; // texture alpha value
private int fadeDir = -1; // the direction to fade: in = -1 or out = 1
void OnGUI()
alpha += fadeDir * fadeSpeed * Time.deltaTime;
alpha = Mathf.Clamp01(alpha);
GUI.color = new Color(GUI.color.r, GUI.color.g, GUI.color.b, alpha);
GUI.depth = drawDepth;
GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), fadeOutTexture);
public float BeginFade(int direction)
alpha = 1;
fadeDir = direction;
return (fadeSpeed);
  • Apply Fading script to fadeGameobject in inspector window and give appropriate texture to it.

1.4 Apply Script To Object

  • Apply PanelOne script to panel one and PanelTwo script to panel two gameobject.
  • Apply panelmanager script to PanelManager gameobject.
  • Apply references of panleOne and panelTwo in panelManager gameobject.

1.5 Execute Code

  • Now, run the program and see the effect.
  • Just apply this code in any OnEnable method and it will perform fade in-out operation.
void OnEnable()
//It will find gameobject which has fading script and will call its method.
GameObject.Find("FadeGameObject").GetComponent<Fading>(). BeginFade(-1);
