How to reduce save and load times

[RyanNguyen]

Hi Joel,
What do I need to be able to use multiple threads to load a large amount of objects with Easy Save 3?
I have an idea that using 5 threads to instantiate 5000 objects, each thread will initialize 1000 objects is this possible and how can I do that?
For now I use this code to save and load game from Easy save 2
How can I use thread solution with this save and load code ?

Code: Select all

// To Save.
using(var writer = ES2Writer.Create("myFile.txt"))
{
    writer.Write(CreatedObjects.Count);
    foreach(var uniqueID in CreatedObjects)
    {
        writer.Write(uniqueID.id);
        writer.Write(uniqueID.prefabName);
        writer.Write(uniqueID.transform);
    }
    writer.Save(false);
}

// To Load.
using(var reader = ES2Reader.Create("myFile.txt"))
{
    int count = reader.Read<int>();
    // Optional: You may want to destroy each object in the createdObjects list and clear the list here
    // to prevent duplicates. I haven't done so in this example however.

    for(int i=0; i<count; i++)
    {
        int id = reader.Read<int>();
        string prefabName = reader.Read<string>();

        // Get your prefab and instantiate it.
        var prefabInstance = UniquePrefabManager.InstantiatePrefab(prefabName);
        // Read the Transform into the prefab instance's Transform using self-assigning load.
        reader.Read<Transform>(prefabInstance.transform);
    }
}

Thank you Joel.

Hi there,

You would only need to create one thread to do your saving and loading in, not multiple threads.

For more information on threads I recommend looking at tutorials online. For example, this one (this is not affiliated with us).

Be aware that although Easy Save is thread safe, the data you're saving might not be, so might not work with threads.

All the best,
Joel

Hello,

It's great that it's possible to have more cached files for loading at the same time. I have game save file opened and meantime some other stuff is being loaded from different files.

But I've been wondering if I should do some cleaning once loading from cached file is done? Before, when using traditional loading from File, I've just set file to null at the end.

Code: Select all

ES3File file = new ES3File(fileName);
bool result = file.Load<bool>(loadKey);
file = null;

Hi there,

If you're using ES3File then setting it to null is fine.

All the best,
Joel

Thanks, but it was my previous setup. Now I use cache files and here I am not sure if this is enough:

Code: Select all

ES3.CacheFile(fileName, settings: saveSettings);
bool result = ES3.Load<bool>(loadKey, fileName, saveSettings);

No cleaning at the end necessary?

Hi there,

If you're using the caching save location then you can use ES3.DeleteFile to remove the file from the cache.

All the best,
Joel

But it just deletes file I stored to the disk with StoreCachedFile

ES3.StoreCachedFile(fileName, settings: saveSettings)
ES3.DeleteFile(fileName, settings: saveSettings);

I guess there is no need to clean memory then?

[Joel]

Hi there,

Does your 'saveSettings' ES3Settings have the save location set to Cache?

All the best,
Joel

I do. But I probably used same settings also for different loading which deleted the file. My fault.
Thanks again.
