Crafty

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.

Example

   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 Hello and 2D and Component whereas the last will return all entities that have at least one of those components (or).

  Crafty("*")

Passing * will select all entities.

  Crafty(1)

Passing an integer will select the entity with that ID.

Finding out the ID of an entity can be done by returning the property 0.

   var ent = Crafty.e("2D");
   ent[0]; //ID
