Multiplayer Event Handler

mikereichle · April 12, 2013, 8:53pm

I have been implementing the multiplayer cloud and have been running into a limitation in the multiplayer handler. I want to be able to run different code blocks from the handler based on the calling code block… I have not figured out a good way to do this… #1 option I came up with was to use a global variable, which I would rather not do. The second option was to modify corona_cloud_code.lua to accept a variable event.type so that I can have custom event.type’s for each calling code block… This is what I did:

I added the source parameter to the cloud core… This lets me run a differerent event.type for each code block…

function coronaCloudController.getRecentMoves(matchID, limit, source) &nbsp;&nbsp;&nbsp;&nbsp;local params = "auth\_token="..coronaCloudController.authToken &nbsp;&nbsp;&nbsp;&nbsp;local path = "matches/"..matchID.."/get\_recent\_moves.json" &nbsp;&nbsp;&nbsp;&nbsp;-- Force get all moves &nbsp;&nbsp;&nbsp;&nbsp;params = params.."&criteria=all" &nbsp;&nbsp;&nbsp;&nbsp;-- Check if limit provided, if so add param &nbsp;&nbsp;&nbsp;&nbsp;if (limit ~= nil) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;params = params.."&move\_count="..limit &nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;-- set currentUser when it gets it &nbsp;&nbsp;&nbsp;&nbsp;local &nbsp;function networkListener(event) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (event.isError) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if coronaCloudController.debugEnabled then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print(coronaCloudController.debugTextPrefix .. "Network Error") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print(coronaCloudController.debugTextPrefix .. "Error: "..event.response) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return false &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if coronaCloudController.debugEnabled then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print(coronaCloudController.debugTextPrefix .. "Recent Match Moves: "..event.response) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;local response = json.decode(event.response) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-- Decode content - Convenient! &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-- TODO: Need to made it iterate through all moves, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-- not just one. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (response[1] ~= nil) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if coronaCloudController.debugEnabled then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print(coronaCloudController.debugTextPrefix .. "Decoding Content") &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;response[1].content = \_b64dec(response[1].content) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if source == nil then &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Runtime:dispatchEvent({name="Multiplayer", type="RecentMoves", results=response}) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Runtime:dispatchEvent({name="Multiplayer", type=source, results=response}) &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end &nbsp;&nbsp;&nbsp;&nbsp;end &nbsp;&nbsp;&nbsp;&nbsp;\_getCC(path, params, networkListener) end &nbsp;

Obviously I don’t want to have to keep track of changes to this file as corona updates it…

#1, does anyone have a better idea?

#2, This would seem to be an easy to make addition to all of these functions to make them move flexible. Corona?

Hi @mikereichle.

The library you are using is pretty much the stock Game Minion library that we made a few tweaks to, and for the most part it works pretty well. We have taken feed back from the community and the beta testers and we are building a new Lua library that will be much more Corona like and it will be coming out very soon.
