Select a set of or single entities by components or an entity's ID.
Crafty uses syntax similar to jQuery by having a selector engine to select entities by their components.
Crafty("MyComponent") Crafty("Hello 2D Component") Crafty("Hello, 2D, Component")
The first selector will return all entities that have the component
MyComponent. The second will return all entities that have
Component whereas the last will return all entities that have at least one of those components (or).
* will select all entities.
Passing an integer will select the entity with that
Finding out the
ID of an entity can be done by returning the property
var ent = Crafty.e("2D"); ent; //ID
