Portal configuration of event-based Stats

This topic describes the procedures for adding and changing stat rules in the Partner Center service configuration for a title. Player stats are created and updated according to the stat rules that are triggered when a game sends events to Xbox services.

For an introduction to Xbox services configuration, see Portal configuration overview.

What is a stat rule?

Stat rules are triggered when an event with a particular name is received by the Xbox data platform service. Triggering of a stat rule (by sending an appropriate event) causes the service to create or update one or more player stats.

Player stats are defined by the developer, calculated by the Xbox services data platform service, and stored as name-value pairs on a per-user basis. Here are a few examples of player stats.

• Total number of zombies killed with a shotgun in hard difficulty
• Highest number of enemies defeated in a match
• Fastest time for completing a race
• Name of the car driven most recently

Player stats can be displayed on the player's game hub UI as featured or hero stats, displayed in leaderboards, and used to unlock achievements.

Individual stat rules can be configured to produce one of the following:

• A single instance of a player stat
• Multiple instances of a player stat that are based on a stat template

For information about stats and stat rules, see the following topics.

• Event-based Stats overview
• Event-based Stat rules overview
• User stats scenarios

The following diagram shows the flow of an event that triggers stat rules that update stat instances.

Prepare to configure a stat rule

Prerequisite: Because stat rules are based on events, you must create an event before you can create a stat rule. For more information, see Portal configuration of events.

1. Sign in to your account on Partner Center. The Overview page appears, showing a list of products.

2. Find and select your title. The Game overview page appears, shown as follows.

   

3. In the left navigation that has a gray background, select Xbox Live to expand it, and then select Gameplay settings. The Gameplay Setting page appears, shown as follows.

   

4. At the top of the page, select the Player stats menu, and then select Stat rules, shown as follows. In this Partner Center UI, "player stats" means "event-based User Stats."

   

   On the Gameplay Setting page, the Events and stat rules page appears, shown as follows.

   

   Initially, the table at the bottom of the page is empty: "No player stats configured".

5. On the Events and stat rules page, configure the events and stat rules that are based on those events. For details, see the following sections.

Create a stat rule

Prerequisite: Stat rules are based on events. As a result, you must create an event before you can create a stat rule. For more information, see Portal configuration of events.

1. Go to the Events and stat rules page as described in the previous section.

2. In an event row, in the Actions column on the right, select the ellipsis button (...), and then select New stat rule, shown as follows.

   

   The Add stat rule dialog appears, shown as follows.

   

   • Event fields added to the stat rule

     • Use this optional field to select fields that are included in the base event as part of the stat rule.
     • In the dropdown, select a field to add to the stat rule. You can add multiple fields this way. The selected fields are appended to the stat rule's root name and separated by the dot (.) character.
     • To remove a field, select the X next to its name.

   • Stat rule name
     Specify a name that characterizes the stat rule and that you can easily remember and recognize. Names of stat rules are composed of a root name, optionally followed by one or more fields that are separated by the dot (.) character. For more information about the naming requirements of stat rule names, see Event-based Stat rules overview.

   • Operator
     Select one of the following operators.

     • Sum
       Increment the existing stat value by the value that's specified in the Parameter field.

     • Min
       Use the minimum of the existing stat value and the Parameter field's value.

     • Max
       Use the maximum of the existing stat value and the Parameter field's value.

     • Replace
       Replace the stat value with the value that's specified in the Parameter field.

       We don't recommend using the Replace operator for stats that drive achievements. Events aren't always processed in order, and this operator might cause an achievement to never unlock. Instead, use the SUM operator.

   • Parameter
     Specify the value to use in the operator that was selected in the Operator field.

     • If you want to use a static number that you specify, select the literal option button and specify the value in the box that follows the option button.

     • If you want to use the value of a field, select the field option button and, in the dropdown list that follows the option button, select the field that you want to use.

   • Restrict other features like achievements and featured stats from accessing this info.
     Select this checkbox to make the stat rule private.

   • Only allow changes to this stat from a server event. Client events will be ignored.
     Select this checkbox to indicate that the stat rule is triggered only by events sent via the server-to-server API, not from game clients that are running on the console or PC.

Your new stat rule is now listed on the Events & Stat Rules page whenever the rule's event is selected.

Change an existing stat rule

1. In the Stat rules column on the Events and stat rules page for the product instance, select the stat rule that you want to change.

2. Make the changes in the Update stat rule dialog for the event.

3. Select Save.

Edit a stat rule

Editing a stat rule takes place when a stat rule's name or an event field has been removed, added, or reordered. This operation will be treated as a deletion and creation of a new stat rule. All stat instances will be deleted as part of editing, according to this definition.

Return to the top of this topic.

Copy an existing stat rule

1. On the Events and stat rules page for the product instance, find the row with the stat rule that you want to delete.

2. Select Copy in the Actions column in that row.

3. Make your changes in the Update stat rule dialog for the event.

4. Select Save.

Return to the top of this topic.

Delete an existing stat rule

1. On the Events and stat rules page for the product instance, find the row with the stat rule that you want to delete.

2. Select Delete in the Actions column in that row.

3. Select Delete in the Confirmation dialog.

The following diagram shows that deleting a stat event rule deletes any dependencies on that rule.
