Getting StartedHaxe

Haxe Haxe

You’re encouraged to use this SDK along with any Haxe Game Engine, such as: OpenFL, Kha, HaxeFlixel, Heaps, HaxePunk, etc.

Installation

Install colyseus from haxelib:

Terminal
haxelib install colyseus

Usage

Connecting to server:

main.hx
import io.colyseus.Client;
import io.colyseus.Room;
 
var client = new Client('ws://localhost:2567');

Joining to a room:

See how to generate your RoomState from State Synchronization → Client-side Callbacks

main.hx
client.joinOrCreate("room_name", [], RoomState, function(err, room) {
    if (err != null) {
        trace("JOIN ERROR: " + err);
        return;
    }
 
    room.state.entities.onAdd(function(entity, key) {
        trace("entity added at " + key + " => " + entity);
 
        entity.onChange(function (changes) {
            trace("entity has been changed");
        });
    })
 
    room.state.entities.onChange(function(entity, key) {
        trace("entity changed at " + key + " => " + entity);
    })
 
    room.state.entities.onRemove(function(entity, key) {
        trace("entity removed at " + key + " => " + entity);
    })
});

Other room events

Room state has been updated:

main.hx
room.onStateChange += function(state) {
  // full new state avaialble on 'state' variable
}

Message broadcasted from server or directly to this client:

main.hx
room.onMessage("type", function (message) {
  trace(client.id + " received on " + room.name + ": " + message);
});

Server error occurred:

main.hx
room.onError += function() {
  trace(client.id + " couldn't join " + room.name);
}

The client left the room:

main.hx
room.onLeave += function() {
  trace(client.id + " left " + room.name);
}

Running the demo project

The example project can be compiled to html5, neko, cpp, ios, etc.

It uses the state_handler room from the colyseus-examples project, which you can find here.

Compiling the demo project to html5

Terminal
git clone https://github.com/colyseus/colyseus-hx.git
cd colyseus-hx/example/openfl
lime build project.xml html5

You can see the demo project live here.

ios target caveats

You may need to manually apply this patch in order to compile for iOS: HaxeFoundation/hxcpp@5f63d23
