-Serpentity is a simple entity framework inspired by Ash.
-
-Usage:
-
- const Serpentity = require('serpentity');
-
-## Instantiating an engine
-
- const engine = new Serpentity();
-
-Add entities or systems, systems are added with a priority (the smaller
-the number, the earlier it will be called):
-
- engine.addEntity(entityFactory());
- engine.addSystem(new GameSystem(), priority);
-
-Update all systems:
-
- engine.update(dt);
-
-Remove entities or systems:
-
- engine.removeEntity(entityReference);
- engine.removeSystem(systemReference);
-
-## Creating Entities
-
-Entities are the basic object of Serpentity, and they do nothing.
-
- const entity = new Serpentity.Entity();
-
-All the behavior is added through components
-
-## Creating Components
-
-Components define data that we can add to an entity. This data will
-eventually be consumed by "Systems"
-
- const PositionComponent = class PositionComponent extends Serpentity.Component {
- constructor(config) {
-
- this.x = 0;
- this.y = 0;
-
- super(config);
- }
- };
-
-You can add components to entities by using the add method:
-
- entity.addComponent(new PositionComponent());
-
-
-Systems can refer to entities by requesting nodes.
-
-## Working with Nodes
-
-Nodes are sets of components that you define, so your system can require
-entities that always follow the API defined in the node.
-
- const MovementNode = class MovementNode extends Serpentity.Node;
- MovementNode.position = PositionComponent;
- MovementNode.motion = MotionComponent;
-
-You can then request an array of all the nodes representing entities
-that comply with that API
-
- engine.getNodes(MovementNode);
-
-## Creating Systems
-
-Systems are called on every update, and they use components through nodes.
-
- const TestSystem = class TestSystem extends Serpentity.System {
- added(engine){
-
- this.nodeList = engine.getNodes(MovementNode);
- }
-
- removed(engine){
-
- this.nodeList = undefined;
- }
-
- update(dt){
-
- for (const node of this.nodeList) {
- console.log(`Current position is: ${node.position.x},${node.position.y}`);
- }
- }
- };
-
-## That's it
-
-Just run `engine.update(dt)` in your game loop :D
