Stat/Attribute Manager

The Stat Manager (AC_StatManager) is responsible for managing all stats and attributes in the project, both for player and AI. It works similarly to the Action Manager by instantiating each stat as a UObject at runtime, based on either a provided map or a data table. This component is designed to be data-oriented and event-driven, ensuring real-time responsiveness and integration with other systems.

It is added to the Base Character class by default (B_Base_Character).

How It Works

1. Stat Initialization:

   • At startup, the AC_StatManager:

     • Loads stats from the provided data table or Stats[] map.

     • Creates an instance of each stat as a UObject for modular and extensible management.

   • The player's class asset provides base values for the attributes.

2. Stat Tracking:

   • Maintains a centralized map of stat instances, allowing quick retrieval through Gameplay Tags.

3. Stat Modification:

   • Provides methods to:

     • Increment or decrement a stat by a given value (e.g., apply damage, buffs).

     • Query the current or base value of a stat.

     • Level up the player.

4. Event Dispatching:

   • Changes to stat values automatically trigger event dispatchers, which are typically listened to by:

     • UI Widgets (e.g., updating health bars, stamina meters).

     • Other Components (e.g., triggering status effects or activating abilities).

Adjusting Which Stats/Attributes to Initialize

The Stats/Attributes a character will have depends on what the Stat Manager is provided. Stats can be provided through a data table or through the Stats[] map in AC_StatManager:

Example Usages

Adjust Stats:

Find/Get Stats:

Toggle Regeneration for Compatible Stats/Attributes:

Adjust Player Level Manually

Player level is handled automatically through attribute increase from the Campfire. However, you can also manually increase/decrease level using the Stat Manager.
