What’s going on? xAPI Against Humanity The entire game is supported by xAPI statements. The LRS is being used as a simple data base, the game is doing all the “work”

On start: What’s going on? xAPI Against Humanity First person in sends xAPI statement to create the group, with ID What’s going on? Next 3 people – checks to see if a group ID is open, added to that group Fourth person in sends xAPI statement closing the group

Send an xAPI statement representing that player P formed the statement referenced by stID. verb: "formed" In the context include the activity ID of the game verb (the content page where we formed this sentence), and the registration ID

xAPI Against Humanity Cool things we learned

Super Cool Cool things we learned xAPI Against Humanity You can use the LRS as a simple database Cool things we learned You can create content with behaviours that depend on how other users have consumed/interacted with it

Registration IDs Cool things we learned xAPI Against Humanity An xAPI client can use multiple registration IDs each for a different purpose:  In the game, each room is associated with a unique registration ID All game activities use the registration ID of the room All other xAPI statements use the main registration ID, if any. Cool things we learned

Registration IDs Cool things we learned xAPI Against Humanity More than one xAPI client can use the same registration ID All players in the same room use the same registration ID for their game activities.  To poll the room activities (all players in the room) we perform a statements query that looks for activities with that registration ID.  Cool things we learned

Voiding Statements Cool things we learned xAPI Against Humanity Voiding statements came in handy: To close a game room, i.e. avoid more people joining it we simply void the statement that opened the room. A statement can be voided by any xAPI client, even if the client that created the original statement is another one.  Cool things we learned
