Need help very badly, how to save changes/overrides in prefab for instantiate in next scene

hello guys, i am working on endless runner game, i have made a character select and also character customize. Basically in customize i change the material of selected character with a script when button is pressed (keycode.c) . but when i instantiate that prefab in game scene it instantiates with the default material, since changes are not saving in prefab, i am instantiating prefab from Resources folder. is there is way way for saving those changes in prefab automatically before instantiating it?

here the video link for system i made.

script files

this is for material change.

Code (CSharp):

1. using UnityEngine;
2.  
3. namespace RunnerGame
4. {
5.     public class MaterialChanger : MonoBehaviour
6.     {
7.         [Header("Components")]
8.         public SkinnedMeshRenderer skinnedMesh;
9.         public CharacterSelect selectedCharacter;
10.         public CharacterControl control;
11.  
12.         [Header("Variables")]
13.         public Material[] materials;
14.         int arraycount = 0;
15.  
16.         private void Awake()
17.         {
18.             skinnedMesh = GetComponentInChildren<SkinnedMeshRenderer>();
19.             control = GetComponent<CharacterControl>();
20.         }
21.         private void Update()
22.         {
23.             if (Input.GetKeyDown(KeyCode.C))
24.             {
25.                 if (selectedCharacter.SelectedCharacter == control.Type)
26.                 {
27.                     arraycount++;
28.  
29.                     if (arraycount >= materials.Length)
30.                     {
31.                         arraycount = 0;
32.                     }
33.                     skinnedMesh.material = materials[arraycount];
34.                 }
35.             }
36.         }
37.     }
38. }

Code (CSharp):

as you can see in video i selected with green material but in game scene it still instantiate with red.

Game Scene Character.

 

I don't think you can (or should) allow your game to permanently change a prefab at runtime.

Instead, I suggest you either:

a) Once you have customized one instance of the prefab, set it to DontDestroyOnLoad and continue to use the same instance in all future scenes

b) Store a list of all the changes you made in some sort of custom data structure somewhere, and then whenever you create a new instance of the prefab, immediately apply all of those same changes again

 

I'd suggest "b", as you may later want to include a save/load system and b's solution here will be immediately useful for such a system in addition to resolving the current issue.

 

I don't know how to do the 'b' any tutorial or blog for that would be good or rough idea with script. Problem with a option 'A' is that character in game view starts with wrong position, since I've characters standing in line with offset of 2 from each other, what I'm doing is instantiate character on the position of empty game exist in game scene. Thanks for help in advance

 

I'll be needing that too

 

The most straightforward way to preserve information when loading a new scene is to put it in some kind of singleton object. This could either be a MonoBehaviour that is attached to a DontDestroyOnLoad object, or it could be a plain C# object (non-MonoBehaviour) stored in a static variable.

You can probably find lots of tutorials on making singletons pretty easily.

 

I am using singleton alot in my game for mangers but, i think i know what you mean i did that had same position problem, I'll send you code later for confirming. It's 5 am here i probably should sleep now. But it would be great if you check later when i post, thanks for helping.
