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

getComponentTypeID
ComponentID getComponentTypeID() noexcept
Gets the unique ID for a given component type.
Definition ECS.h:39

TextureManager.h
A static utility class for loading and drawing textures.

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

Animator
Manages sprite sheet animations and transitions between them using a state machine.
Definition Animator.h:15

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

Sprites
A component that gives an entity a visual representation using a texture.
Definition Sprites.h:18

Sprites::recalcSpriteDimensions
void recalcSpriteDimensions()
Recalculates the sprite's on-screen dimensions based on texture size and transform scale.
Definition Sprites.cpp:32

Sprites::init
void init() override
Initializes the sprite, getting the entity's transform and loading the texture.
Definition Sprites.cpp:14

Sprites::draw
void draw() override
Draws the sprite's current texture to the screen.
Definition Sprites.cpp:28

Sprites::update
void update() override
Updates the destination rectangle for rendering based on the transform.
Definition Sprites.cpp:21

Sprites::Sprites
Sprites(const char *tex, int nFrames, int mSpeed, bool loop)
Constructs a sprite with simple, built-in animation capabilities.

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