-var engine = Serpentity();
-
-Add entities or systems:
-
- engine.addEntity(entityFactory());
- engine.addSystem(new GameSystem());
-
-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.
-
- var 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"
-
- Class("PositionComponent").inherits(Serpentity.Component)({
- prototype : {
- x : 0,
- y : 0
- }
- });
-
-You can add components to entities by using the add method:
-
- entity.add(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.
-
- Class("MovementNode").inherits(Serpentity.Node)({
- types : {
- position : PositionComponent,
- 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.
-
-Class("TestSystem").inherits(Serpentity.System)({
- prototype : {
- added : function added(engine){
- this.nodeList = engine.getNodes(MovementNode);
- },
- removed : function removed(engine){
- this.nodeList = undefined;
- }
- update : function update(dt){
- this.nodeList.forEach(function (node) {
- console.log("Current position is: " + node.position.x + "," + node.position.y);
- });
- }
- }
-});
-
-## That's it
-
-Just run `engine.update(dt)` in your game loop :D
-
-## TO-DO
-
-* Removing components
-* Implement the ashteroids demo (Serpentoids)
-* Actually check performance
