Description

helios::engine::runtime::spawn::dispatcher

Command dispatchers for spawn operations.

Overview

This module contains dispatchers that route spawn and despawn commands to the appropriate managers for processing. Dispatchers implement the visitor pattern, allowing the CommandBuffer to route commands without knowing their concrete types.

Key Classes

Dispatcher	Handles	Purpose
SpawnCommandDispatcher	SpawnCommand	Routes spawn commands to SpawnManager
DespawnCommandDispatcher	DespawnCommand	Routes despawn commands to SpawnManager
ScheduledSpawnPlanCommandDispatcher	ScheduledSpawnPlanCommand	Routes scheduled plans to SpawnManager

Dispatchers are registered with the CommandBuffer during game initialization:

 commandBuffer.addDispatcher<SpawnCommandDispatcher>();

 commandBuffer.addDispatcher<DespawnCommandDispatcher>();

 commandBuffer.addDispatcher<ScheduledSpawnPlanCommandDispatcher>();

Usage

Commands are added to the buffer by systems and automatically routed during flush:

 // In a system

 commandBuffer.add<SpawnCommand>(profileId, spawnContext, count);

 commandBuffer.add<DespawnCommand>(entityGuid, profileId);

 

 // During flush, dispatchers route commands to handlers

 commandBuffer.flush(gameWorld);
