How to Make Transition Screen Between Levels

Creating a transition with a black screen between levels in a game or interactive application can help smooth out the player's experience and provide a sense of continuity. To implement this transition, you'll need to use game development tools or a programming language with graphics capabilities.

Below, I'll outline a general process to achieve this effect using Unity, a popular game development engine. However, the principles can be adapted to other engines or frameworks.

1- Set Up Your Levels: Ensure that you have multiple levels or scenes prepared in your game. Each level should be a separate scene with its own content.

2- Create an empty gameObject in the hierarchy in the Unity (e.g Level Loader).

3- Right click on the empty game object-> UI -> Canvas and rename it.

4- Adding the black image by right click on the canvas game Object -> UI ->Image.

5- Choose the Color you want for example choose the balck color (in the inspector).

6- Click on the Add component in the inspector and add the Canvas group.

7- Make the settings of the canvas group (Alpha 0 and unchecked the interactable and blocks raycasts)

8- Go to the canvas object that we made in the step 3.

9- Create animation from the animation window at 1 second make the black image with no color by making the alpha 0 and in the 1 second making the black image in scene by making alpha 1.(e.g making 2 animations end and start with opposite and don't forget to stop the loop time of each animation)

10- Add a script for the parent object of the canvas


using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class levelLoader : MonoBehaviour
{

    public Animator transition;

   
    // Update is called once per frame
    void Update()
    {
        if(Input.GetKeyUp(KeyCode.Escape))
        {
            LoadNextLevel();
        }
    }


    public void LoadNextLevel()
    {
        StartCoroutine(loadLevel(SceneManager.GetActiveScene().buildIndex + 1));
    }

    IEnumerator loadLevel(int levelIndex)
    {
        transition.SetTrigger("start");
        yield return new WaitForSeconds(2);
        SceneManager.LoadScene(levelIndex);
    }
}

In summary, this script is designed to do the following:

When the Escape key is released (Input.GetKeyUp(KeyCode.Escape)), it initiates a scene transition.
The scene transition involves triggering an animation identified by the "start" trigger on the transition Animator component.
After a 2-second delay (you can adjust this), it loads the next scene in the build order using SceneManager.LoadScene().

You can attach this script to a GameObject in your scene and assign the transition Animator Controller to it in the Unity Inspector. When the Escape key is released or when you call LoadNextLevel() from another script or event, it will trigger the transition animation and load the next scene.
