 # helios::engine::runtime::messaging::command

 

 Command pattern implementation for deferred action execution.

 

 This module provides the Command pattern implementation for the helios engine. Commands encapsulate game actions that can be buffered and executed at a later point in the game loop, enabling decoupled input handling and action processing.

 

 **Components:**

 

 - **TargetedCommand** - Abstract base for commands targeting a specific GameObject.

 - **WorldCommand** - Abstract base for commands operating on the entire GameWorld.

 - **CommandBuffer** - Queue for buffering and batch-executing commands.

 - **TargetedCommandDispatcher** - Abstract dispatcher interface for TargetedCommand handling.

 - **WorldCommandDispatcher** - Abstract dispatcher interface for WorldCommand handling.

 - **TypedTargetedCommandDispatcher** - Type-safe dispatcher template for specific TargetedCommand types.

 - **TypedWorldCommandDispatcher** - Type-safe dispatcher template for specific WorldCommand types.

 

 **Execution order:**

 

 During `CommandBuffer::flush()`:

 1 **WorldCommands** are processed first (global game actions like spawning).

 2 **TargetedCommands** are processed second (per-entity actions like movement).

 @namespace helios::engine::runtime::messaging::command

 @brief Command pattern implementation for deferred action execution.

 @details Provides TargetedCommand and WorldCommand base classes for encapsulating game actions. Commands are buffered in CommandBuffer and executed during the game loop update phase. Dispatchers enable type-safe routing to specialized handlers via the Visitor pattern.
