Handle events in different thread

[Flawe]

I'm having some trouble handling events in a second thread. I do the rendering and the logic on the main thread but I spawn off a second thread for the event loop. This loop basically calls GetEvent() on the render window but it never seems to catch any events.

I have the window activated on the main thread and deactivated on the event thread, does that matter? Do I need something specific set up for the input to work on this second thread?

Thanks for any help

So I read that you can't handle the input on a different thread. Fair enough, what I do is this:

Code: [Select]


void main() {
Thread mainThread( &GameManager::Init, GetGameManager() );

sf::Event evt;
bool running = true;
while( running ) {
if( renderWindow == NULL ) {
ThreadSleep( PTimeMS( 25 ) );
continue;
}

while( renderWindow->GetEvent( evt ) ) {
if( evt.Type == sf::Event::Closed ) {
GetGameManager()->StopGame();
running = false;
}
}

ThreadSleep( PTimeMS( 10 ) );
}

mainThread.join();
}


renderWindow is an extern which is set up in GameManager::Init. Everything works render wise and "mainThread" executes as expected. Only it seems that GetEvent never returns true as all input actions are ignored.

Ok my bad, I actually created the renderWindow on a different thread. So in conclusion: create the window on the main thread, handle events on main thread, have party on many other threads.

I'll get my coat now, thanks for your time!

I think you just need to handle events in the same thread that created the window, but this can be another thread than the main one.
