ChannelService

ChannelService is created by channel component which is a default loaded component of pomelo and channel service would be accessed by app.get(‘channelService’).

 createChannel(name)getChannel(name,create) create = truedestroyChannel(name)pushMessageByUids(route, msg, uids, opts, cb)broadcast(stype, route, msg, opts, cb)

Channel

add(uid, sid)   //uid - user id//sid - frontend server id which user has connected to
leave(uid, sid)
getMembers()
getMember(uid)
destroy()
pushMessage(route, msg, opts, cb)

Sample

Mainly Used
- getChannel(name,create)
- add(uid, sid)
- pushMessage(route, msg, opts, cb)
- leave(uid,sid)

  var exp = module.exports;//get channelvar getChannel = exp.getChannel = function() {if(channel) {return channel;}channel = pomelo.app.get('channelService').getChannel('area_' + id, true);return channel;};//pushMessagegetChannel().pushMessage({route: 'onPickItem', entityId: args.entityId, target: args.target, score: treasure.score});/*** Add entity to area * @param {Object} e Entity to add to the area.*/exp.addEntity = function(e) {    //e is a entity,it maybe a playerif (e.type === EntityType.PLAYER) {getChannel().add(e.id, e.serverId);addEvent(e);               //add event listenerplayers[e.id] = e.entityId;}return true;};
