Akka Actors in games

[Brian Berard]

Hi everyone,

I'm really interested in using Akka Actors for my game, since I feel like actors play well in a game world. I only have one problem... I'm currently using OpenGL for rendering (via LibGDX). When I start a LibGDX application, it spawns its own thread that contains the OpenGL context. Since I need the OpenGL context for rendering, I'm wondering if there's anyway to configure an actor to run with a PinnedDispatcher on the same thread as OpenGL without modifying the LibGDX library. Either that, or I could probably get away having actors publish their state (Texture, x, y) on each TickMessage to some location that I can access from outside of the Actor system. 

Has anyone done anything like this before?

PinnedDispatcher will create its own thread. You cannot tell it to use another existing thread. You can of course write your own dispatcher.

yes, that is probably easiest

Is there an easy way to do such a thing? That is, to maintain a list of objects to be rendered (Texture, x, y) in some central actor and make that value available outside of the actor system?

If you can't do it with messages you have to resort to let the actor write the value to some place where the rendering engine can read. A thread safe implementation is your responsibility.
