Constants.h
Defines global constants and enums used throughout the engine and game.

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

Transform.h
Defines the component for managing an entity's position, rotation, and scale.

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

Collider::tag
std::string tag
A tag to identify the type of collider (e.g., "player", "wall").
Definition Collider.h:24

Collider::isColliding
const bool isColliding(std::string collTag)
Checks if this collider is currently colliding with any collider of a specific tag.
Definition Collider.cpp:63

Collider::onCollision
void onCollision(Collider &other)
Executes the collision callback function.
Definition Collider.cpp:59

Collider::update
void update() override
Updates the collider's position and checks for collisions against other colliders.
Definition Collider.cpp:38

Collider::init
void init() override
Initializes the collider by linking it to the entity's transform.
Definition Collider.cpp:29

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

Transform
Stores an entity's position, velocity, scale, and rotation.
