Fix: Godot C# Threaded Resource Load Blocks Main Thread

Code uses ResourceLoader.LoadThreadedRequest then immediately LoadThreadedGet — and the game still hitches. The Get call waited for the background thread.

Request, Poll, Then Get

ResourceLoader.LoadThreadedRequest(_path);

public override void _Process(double delta)
{
    var status = ResourceLoader.LoadThreadedGetStatus(_path);
    if (status == ResourceLoader.ThreadLoadStatus.Loaded)
    {
        var res = ResourceLoader.LoadThreadedGet(_path);
        OnLoaded(res);
        SetProcess(false);
    }
}

Calling LoadThreadedGet before the status is Loaded makes it a blocking wait — you lose the whole point of threaded loading.

Show Progress

LoadThreadedGetStatus has an out-progress parameter (a float array). Feed it to a loading bar so the wait is visible, not a freeze.

Handle Failure States

The status can also be Failed or InvalidResource. Branch on those — don’t assume the load always succeeds.

Verifying

Trigger a large resource load. The game keeps rendering at full frame rate; the loading bar advances; the resource appears when ready — no hitch.

“Threaded load = Request, poll status, Get only when Loaded. Get-before-Loaded is just a blocking load.”

Wrap this in a small ThreadedLoad helper with a callback — the request/poll/get dance is identical everywhere you stream content.
