Entities

An entity itself is not that special, it is just a container for components. It also has position, scale, rotation, and z attributes which can be used by e.g. rendering. Components can be inserted upon instantiation or via the << method.

The Entity class defines some convenience functions such as the has method to check wether it contains one ore more kinds of components and the [] and []? methods for component access via type. One can also get the id or get and set the array of components.

Any entity can be flagged as dead by calling Entity#suicide. The flag state can be checked via the Entity#alive? getter.

You can find an example in the components section.
