Detailed Description

System managing entity boundaries and screen limits.

Handles entities going out of bounds and applies boundary constraints. Requires Transform component.

Definition at line 22 of file BoundarySystem.hpp.

Constructor & Destructor Documentation

BoundarySystem()

ecs::BoundarySystem::BoundarySystem	(	int	screenWidth = 1920,
		int	screenHeight = 1080
	)

Constructs a BoundarySystem with specified screen dimensions.

Parameters

screenWidth	Width of the screen/game area (default: 1920)
screenHeight	Height of the screen/game area (default: 1080)

Definition at line 16 of file BoundarySystem.cpp.

~BoundarySystem()

ecs::BoundarySystem::~BoundarySystem ( )

overridedefault

Default destructor.

Member Function Documentation

getComponentMask()

ComponentMask ecs::BoundarySystem::getComponentMask ( ) const

overridevirtual

Gets the component mask for this system.

Returns

ComponentMask requiring Transform component

Implements ecs::ISystem.

Definition at line 64 of file BoundarySystem.cpp.

Referenced by update().

setScreenSize()

void ecs::BoundarySystem::setScreenSize	(	int	width,
		int	height
	)

Updates the screen dimensions.

Allows dynamic adjustment of boundary limits when screen is resized.

Parameters

width	New screen width
height	New screen height

Definition at line 59 of file BoundarySystem.cpp.

References _screenHeight, and _screenWidth.

update()

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

overridevirtual

Checks entities against screen boundaries.

Checks entities against boundaries and marks out-of-bounds entities for destruction.

Destroys entities that have moved outside the screen bounds (with a 100-pixel margin). Typically used for projectiles and enemies.

Parameters

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

Instead of destroying entities directly, this system adds a PendingDestroy component. The server will then:

1. Send EntityDestroyed messages to clients
2. Actually destroy the entities

This prevents interpolation bugs where clients try to interpolate to old positions.

Implements ecs::ISystem.
