Im making a 2D ufo game with 3 scenes in the project i need to merge them so once you complete one it will take you to the next scene but i don’t know how
Why do you feel that you need to merge them. You can just do the following at the completion of each scene
Lets say that you have 3 scenes named “Level1”, “Level2” and “Level3”.
Upon completing Level1 you call
UnityEngine.SceneManagement.SceneManager.LoadScene("Level2");
Upon completing Level2 you call
UnityEngine.SceneManagement.SceneManager.LoadScene("Level3");
