Players are the participants in the game. Events will be processed for players and result in changes to their progress, score, and achievements.
We will track a player's progress for meeting the trigger requirements of Achievements. Additionally, we will track which Achievements a player has already achieved.
We will track a user's total overall score. This may or may not be a criteria for achieving Levels.
Levels might just be a specialized type of achievement that's triggered at certain Total Score thresholds.
Events are the real world or external activities a player was involved in that results in potential progress. The event should contain enough metadata to be a rich description of the overall activity that took place (e.g. Player1 had a pull request accepted by Linux Torvalds. (URL) - (Total Score).).
Events can comprise multiple rules. (e.g. 2xTests Added, 5xUsed Profanity, etc). Rules will have a preconfigured "Points" value that will contribute towards the total score of the event.
An event will have a total Score value that is the sum of each rule met by the activity multiplied by the number of points that rule is worth.
An achievement is a named accomplishment with a set of conditions that will trigger the achivement to be granted. These are challenges designed to entice players to try to meet the conditions to get the achievement.
Achievements can grant rewards. A reward is some action that will happen one time when the achievement is granted to the user. This could be something like making a post to an api to give a user bitcoins, or a post to slack to say that someone owes the player an empanada.
