quad engine
Quad Engine #
Quad Engine is a lightweight graphics rendering engine written in Dart. It is designed to efficiently render quads and utilizes an Entity-Component-System (ECS) architecture for managing entities and their behaviors.
Features #
Quad Rendering: Efficient rendering of quads with customizable textures and transformations.
Entity-Component-System (ECS): Utilizes an ECS architecture for flexible and scalable entity management.
Modular Design: Designed with modularity in mind, making it easy to extend and customize for specific project needs.
Installation #
Install Dart SDK: If you haven't already, install the Dart SDK on your machine. You can download it from the Dart website and follow the installation instructions for your operating system.
Template: Duplicate the template folder included in the repository and rename it. Open the pubspec.yaml file in your chosen text editor and change whats listed below in <>
name: <NAME OF PROJECT>

Update Repository: Lastly you must run the command dart pub update in your terminal or command line application.
Usage #
This is the contents of the template main.dart file. This is a basic empty scene with camera.
import 'package:quad_engine/quad_engine.dart';
class GameScene extends Scene {
@override
void init() {
Camera camera = Camera(); // This is the camera component. Each scene requires a camera component.
Entity cameraEntity = Entity(Transform()).addComponent(camera); // Create a entity to hold our camera component.
cameraEntity.addComponent(MoveComponent()); // Adding a simple free move controller to the camera entity.
addEntity(cameraEntity); // Add the camera entity to the scene.
setSceneCamera(camera, 5.0); // Letting the scene know which camera should be active. Only one camera can be active at a time.
setRenderingMode(RenderingMode.FULL_COLOR); // Telling the engine to draw all sprites at full colors as they are in the sprite sheet.
print("hello world");
}
}
void main() {
Core().start(GameScene()); // The Core() function is called and the start(SCENE_NAME) lets the engine know where to start.

Entities #
Each entity has its own transform, which handles positioning and orientation in the world. Additionally, entities have a list of components, making them adaptable and specialized. These components cover various behaviors and attributes, like rendering properties and interactive features.
Components #
Components are essential elements defining entity behavior and attributes. The currently available components are:
TagComponent: Allows for unique entity identification and referencing via designated string identifiers.
SpriteComponent: Enables entities to effortlessly render sprites and textures onto the screen.
MoveComponent: Provides basic movement control, allowing entities to navigate the environment using standard keyboard inputs (WASD for horizontal movement, space and shift for vertical movement).
LookAtComponent: Empowers entities with dynamic orientation adjustment, ensuring they focus on specific positions within the environment.
Developers have the flexibility to create custom components to extend functionality further. A example custom component is below. This example component prints "hello world" on each update.
class ExampleComponent extends Component {
ExampleComponent();
@override
void init() {
}
@override
void update(Input input) {
print("hello world");
}
@override
void render(Screen screen) {
}
}
