Detailed Description

System managing entity spawning and wave generation.

Handles enemy waves, power-ups spawning, and entity creation based on game progression and patterns.

Processes SpawnRequest queues from Spawner components—the clean ECS way to handle dynamic spawning without tight coupling.

Definition at line 25 of file SpawnSystem.hpp.

Here is the call graph for this function:

◆ getComponentMask()

ComponentMask ecs::SpawnSystem::getComponentMask ( ) const

overridevirtual

Gets the component mask for this system.

Returns: ComponentMask of 0 (this system doesn't filter entities, it creates them)

Implements ecs::ISystem.

Definition at line 146 of file SpawnSystem.cpp.

◆ update()

void ecs::SpawnSystem::update	(	Registry &	registry,
		float	deltaTime
	)

overridevirtual

Manages entity spawning based on wave progression.

Processes spawn requests from Spawner components. Handles the actual entity creation with all components.

Parameters

registry	Reference to the ECS registry
deltaTime	Time elapsed since last frame (in seconds)

Implements ecs::ISystem.
