SceneChangeInUnity

Here's a quick setup guide on how to use change scenes in Unity 2018.3.x ==

• Create new empty GameObject, name SceneChanger or similar
• Create a new C ⋕ Script and drag it onto the SceneChanger Game Object
• Underneath lays an example of code to change scene after a determined amount of seconds

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.SceneManagement;

public class ChangeScene : MonoBehaviour {

   public float sceneChangeTime;
   public string nextScene;

   // Start is called before the first frame update
   void Start()
   {
       StartCoroutine(NextScene());   
   }

   public IEnumerator NextScene()
   {
       yield return new WaitForSeconds(sceneChangeTime);
       SceneManager.LoadScene(nextScene, LoadSceneMode.Single);
   }

}

• In your Unity Inspector on the Scene Changer Script, determine the amount of seconds that must pass for the scene to change
• Drag the Next Scene onto the Inspector
