Who can help me look at this problem

 

"public abstract class Job
{
public bool IsDone
{
get { return _isDone; }
}

public void Start()
{
UnityEngine.Debug.Log("ThreadPool.QueueUserWorkItem(Run);");
ThreadPool.QueueUserWorkItem(Run);
}


protected abstract void Work();


private volatile bool _isDone;

private void Run(object state)
{
Debug.Log("Run Work();");
try
{
Work();
}
catch (Exception ex)
{
Debug.LogException(ex);
}
finally
{
_isDone = true;
}
}
}

"ThreadPool.QueueUserWorkItem(Run);" can be printed ,but "Run Work();" cant not

 

AFAIK threading is not supported in current version of unity WebGL ... browsers needs to be updated first with new technology to support SharedArrayBuffers (share memory across threads) ... meybe in the next year :]

 

Thank you very much!
