// tests/worker.tsimport{PackedScene,ResourceLoader}from"godot";import{JSWorkerParent}from"godot.worker";if(typeofJSWorkerParent!=="undefined"){JSWorkerParent.onmessage=function(m:any){console.log("worker: get message",m);JSWorkerParent.postMessage("worker result");// [EXPERIMENTAL] instantiate a PackedScene in worker thread and transfer it back to master threadletasset=<PackedScene>ResourceLoader.load("res://background.tscn");letobj=asset.instantiate();console.log("[worker] transfering object:",obj);JSWorkerParent.transfer(obj);// worker can terminate itself by calling `close()`// close();}}
