Collider.h
Defines a component for collision detection.

ECS.h
Defines the core classes for the Entity-Component-System (ECS) architecture.

Collider
Provides an entity with a physical bounding box for collision detection.
Definition Collider.h:22

Component
The base class for all components in the ECS.
Definition ECS.h:53

Controller
Translates keyboard input (WASD) into entity movement.
Definition Controller.h:16

Controller::updateKeyDown
void updateKeyDown(SDL_Keycode key)
Updates the state when a key is pressed down.
Definition Controller.cpp:20

Controller::update
void update() override
Calculates and applies velocity to the Transform based on current key states.
Definition Controller.cpp:30

Controller::reload
void reload() override
Resets the controller's state.
Definition Controller.cpp:66

Controller::updateKeyUp
void updateKeyUp(SDL_Keycode key)
Updates the state when a key is released.
Definition Controller.cpp:25

Controller::init
void init() override
Initializes the controller, grabbing the entity's Transform and Collider.
Definition Controller.cpp:10

Transform
Stores an entity's position, velocity, scale, and rotation.
Definition Transform.h:17

Vector2D
A simple struct for 2D mathematics (points, vectors).
Definition Vector2D.h:15
