Hi, I want to save current scene name, player position and scene name for every scene that the player ever was in, and if player saves position in scene that he already was in, it should overwrite previous record. All that data should be saved with binary formater ,and on game load it should read in which scene the player was and load that scene with it’s position. Finally when player goes to diffrent scene it should find in which scene he is and place him in saved coordinates for this scene. I tried to do it with Dictionary of strings and float arrays but it doesnt semm to work.
This is a well-studied process, no need to post about it, just get busy with tutorials.
Load/Save steps:
An excellent discussion of loading/saving in Unity3D by Xarbrough:
Loading/Saving ScriptableObjects by a proxy identifier such as name:
When loading, you can never re-create a MonoBehaviour or ScriptableObject instance directly from JSON. The reason is they are hybrid C# and native engine objects, and when the JSON package calls new to make one, it cannot make the native engine portion of the object.
Instead you must first create the MonoBehaviour using AddComponent() on a GameObject instance, or use ScriptableObject.CreateInstance() to make your SO, then use the appropriate JSON “populate object” call to fill in its public fields.
If you want to use PlayerPrefs to save your game, it’s always better to use a JSON-based wrapper such as this one I forked from a fellow named Brett M Johnson on github:
Do not use the binary formatter/serializer: it is insecure, it cannot be made secure, and it makes debugging very difficult, plus it actually will NOT prevent people from modifying your save data on their computers.
Thanks a lot, It should help.
