Loading game gets stuck.

[GREI]

Hi,
I am a bit confused about how to use the save system.
I have the four components (SaveSystem, Json...) from tutorial attached to the dialogue manager.
Then I let my button perform a bit of code

Code: Select all

    private void SaveGame()
    {

        SaveSystem.SaveToSlot(0);

    }

and

Code: Select all

    private void LoadGame()
    {

        SaveSystem.LoadFromSlot(0);

    }

But when I got something saved and try to load, the game would just freeze and stop working.
Please tell me what I am doing wrong here.
Thanks!

Hi,

Are there any errors or warnings in the Console window?

If you're playing in the Unity editor's play mode, does Unity freeze? Or can you exit play mode?

In the scene that you're loading, is there anything that might call LoadGame() again when the scene starts? This could put the game into an infinite loop.

Hi,
No error messages at all. The entire unity would freeze (i.e. I cannot minise the window or exit play mode ect). After a while it would unfreeze and that's it.
I don't have any other trigger for loading scenes other than the button click, so I think the game is not in a loop.

Please try this:

1. Close and reopen Unity. This will create a fresh Editor.log file (see here for location of file).

2. Reproduce the issue.

3. When Unity unfreezes, don't do anything else in Unity. Examine the Editor.log file. If you jump to the bottom of the file, it should indicate what was going on when Unity froze.

Hi,
it seems that it is repeatedly unloading assets and seriealised fields.

That looks fairly normal. Can you look back further to identify a pattern?

[GREI]

yes, the pattern is "Unloading 3 Unused Serialized files" and "Unloading 59 unused Assets to reduce memory usage. ". They are repeated many many times and it seems that is pretty much all it is doing.

The log has got 120199 lines and over 5MB in size. Majority of them are "Unloading 3 Unused Serialized files" and "Unloading 59 unused Assets to reduce memory usage. "

[Tony Li]

Can you send a reproduction project or the Editor.log file to tony (at) pixelcrushers.com?

If not, do you see any messages that says it's loading (not unloading)?

What versions of Unity and the Dialogue System are you using?

[GREI]

Yeah, I'll send the file over, thanks a bunch!

[Tony Li]

Thank you for sending the project. I replied to your email. The problem is that the Update() method was adding another "SaveGame" and "LoadGame" to the UI buttons every frame. I attached a fixed version of the script that uses the Start() method instead and also uses the SaveSystem class.
