## AutomationPlayerStatistics ##
|
|
## --------------------------------------------------------------------------- ##
|
|
## Periodically takes a snapshot of every player's rank, population, and army. ##
|
|
## These snapshots are used to draw the graphs on the Plus statistics page. ##
|
|
## ##
|
|
## Guarded by NEW_FUNCTIONS_PLUS_STATISTICS. When enabled, snapshots are taken ##
|
|
## for ALL players; however, the statistics tab is only visible to players ##
|
|
## with an active Plus account. ##
|
|
## ##
|
|
## Data is recorded for ALL players, not only Plus users; otherwise, a player ##
|
|
## who purchases Plus would open the page and see an empty graph at the exact ##
|
|
## moment they activated it. ##
