Do you mean that when you play the game, you don’t go to the Main Menu or, after starting from the Main Menu you don’t start at your first level?

If you could show a video of how it looks that would help.

Could you also send your SaveData.cs and PlayerController.cs?

i mean when i export to the game to desktop (the exe file). I run the game and the data wouldnot save. it does work when i play it in the editor.

I understand your issue is in the build, however the code in the editor works the same for the build itself. Thus, I’d like to see how the issue is going on your side of things with a video, and Scripts if it’s a coding issue. There’s also a likelihood it is neither and it leads me to this:

Without the video and scripts I can only guess the causes:

1. Your Bench/Save point is not reliable for interaction and thus the code for interaction can be improved.
2. You are quiting the game by the pause menu which does not have a code for saving the player’s data. Thus entering the game again brings you to your last save point [death or bench].
3. Your PlayerController.cs is not calling SaveData.Instance.LoadPlayerData();
4. If your health is being saved, but not the scene, your SaveData.cs does not include a code for lastScene at least for loading player data.

Oh sorry its acttualy my fault that i commented out the LoadSaveData line of code in the playerController Script. However there is a bug i just found out that i cant not hit the shade. It works fine in the editor

Can you send a picture or video of the Shade’s inspector as well as it’s script? Likely the issue lies with the shade and not the player since the player can attack the other enemies fine.

I’ve tested out your code, it seems to work fine.

I’ve looked at your video again and I think you should test this out again in your Editor. Dying, respawning then fighting the Shade again.

I believe the problem may lie in the fact that the spawned Shade has missing variables, aside from the fact that you should equip it with the “Enemy Hurt” Sound clip. [The console error tells you that there’s a missing audio clip, which you can see in the image you sent of the inspector].

Check that the Shade’s prefab (and by extension the spawned shade from dying) in your prefabs folder has it’s

1. Layer set to Attackable
2. Tag set to Enemy
3. Inspector values all set
4. It’s blood effect
5. It’s hurt Audio Clip
