• this.net.onOpen() - on websocket open
• this.net.onMessage(msg) - on websocket message
• this.net.sendHello(width, height) - send hello message (width and height are optional)
• this.net.ping() - ping server
• this.net.sendNick(nick) - nick is optinal; in brutal.io this method starts the game, beware
• this.net.sendInput(angle, throttle) - send movement
• this.net.sendClick(hold) - send click

World

• this.world.king - {id, x, y} (doesn't work yet)
• this.world.connect() - connect to server
• this.world.entities - object with entities (doesn't work yet)
• this.world.updateMapInfo(view) - update map
• this.world.processLeaderboard(view, op) - process leaderboard data

Utils

• this.utils.getString(view, offset) - get string from dataview
• this.utils.getPlayerName(playername) - get proper nick

Warning

There's a lot of stuff, but you actually don't need anything from this.world, this.utils, you only need movement and click methods, leaderboard, id, rank, minimap, death & kills. Client connects to server and joins the server automatically, and if there's autoplay option, it'll play again on death!
