the dif between LoadSceneMode.Additive and LoadSceneMode.Single

Code (CSharp):

1. LoadSceneMode.Additive
2. LoadSceneMode.Single

can someone explain to me what's the difference between them ?

 

Hi and welcome @raidest45,

Single replaces the current level you have loaded, but if you use additive, it loads the new scene and leaves your current scene loaded too.

 

thnxx sooo much one more thing please ,
look at my code and when i die the sceen didn't want start again

Code (CSharp):

1. public class OnPlayerDie : MonoBehaviour
2. {
3.  
4.     void Start()
5.     {
6.        
7.     }
8.  
9.  
10.     void Update()
11.     {
12.        
13.     }
14.     void OnTriggerEnter2D(Collider2D other)
15.     {
16.          if (other.gameObject.tag == "playerKiller")
17.         {
18.             Destroy(gameObject);
19.             GameObject go = new GameObject("nextLVL");
20.             nextLVL script = go.AddComponent<nextLVL>();
21.             script.LVLname = Application.loadedLevelName;
22.         }
23.        
24.     }
25.  
26. }
27.  

 

To expand on what Olmi said, if you load a scene in Single mode, every GameObject in your current scene will be destroyed unless you call https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html on it.

 

This ^^

Single is pretty easy to understand, but additive is very useful to avoid duplicating work between scenes. Lets say you have a game with 5 levels with different terrain and enemy placements but overall the same gameplay. You can create a different scene for each level and load as Single, but you will be duplicating your UI objects and anything else common in your game across all these scenes. Then it becomes a nightmare to make a change to one of those objects, because you then have to duplicate that change to all the other levels.

Instead you create your objects common to all your levels in its own scene, separate from the what changes between levels. You load that common scene, then additive load the individual level scene.
