Detailed Description

System handling entity movement based on velocity.

Updates entity positions by applying their velocity and speed. Requires Transform and Velocity components.

Definition at line 23 of file MovementSystem.hpp.

Constructor & Destructor Documentation

MovementSystem()

ecs::MovementSystem::MovementSystem ( )

default

Default constructor.

~MovementSystem()

ecs::MovementSystem::~MovementSystem ( )

overridedefault

Default destructor.

Member Function Documentation

getComponentMask()

ComponentMask ecs::MovementSystem::getComponentMask ( ) const

overridevirtual

Gets the component mask for this system.

Returns

ComponentMask requiring Transform and Velocity components

Implements ecs::ISystem.

Definition at line 31 of file MovementSystem.cpp.

Referenced by update().

update()

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

overridevirtual

Updates entity positions based on their velocities.

Applies velocity to transform positions for all moving entities.

Applies velocity vectors and speed to transform positions. Movement is frame-rate independent using deltaTime.

Parameters

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

Implements ecs::ISystem.

Definition at line 14 of file MovementSystem.cpp.
