Save game data on the cloud

jdbc

I am planning to use some cloud service to save game data for share data between devices, but I am not sure on how complicated is to solve conflicts as Google explains here: https://developers.google.com/games/services/common/concepts/cloudsave (Resolution conflicts)

Have anyone solved this issue with some Cloud service when try to save data on a server instead of a local file?

@jdbc it all depends on what you store there
Basically if you for example store levels completed and high scores, in the conflict situation when on one device you are further progressed in game, but on other you have higher highscores, then you probably won't be able to simply take one version, but rather to mix them, taking progression from one and higher scores from other version.
Still it is rather easy

But if you have an RPG like, where you have items and you have used them up and stuff, well you are screwed then

@jdbc, have you tried saving to services like the amazon aws or something similar. That would work for both iOS and android.

Yes I know how to use this kind of services. My question is how to manage save services and conflicts: for example when wifi is offline and you play a game for a while but without updating changes.

@jdbc I am using https://parse.com/ and https://www.openshift.com/ to save and syns data between ios and android. In parse you can create table and then using rest api to save and load data. In openshift you can deploy your own logic using php, java or nodejs system.

How do you solve load and save data when network is down?

I mean for example data has been saved from a tablet device on parse but I am using a mobile device inside a plane (no network then), data in mobile device are out of sync.

I was thinking about using Openshift also for more logic in the server.

Client and server synchronization can be done by checkpoint. When your mobile device is offline, you can save progress on local file, and when it is online, we can compare last checkpoint data to update. ( for example, we will update level = max(onlineLevel, offlineLevel) )

I have already created one openshift account. I will use Java or Python for create some basic REST services. May be Tomcat + Jersey + Java is my first option.

@jdbc, i am using nodejs + mongodb for rest services.
