Overview

+ +

Component Managers are what is used to create individual components which can be attached to entities. When a Component is created from a Component Manager that has accessors given to it, you can set or get the values of those accessors using standard ruby message sending (e.g @component.var = 5), or by using the #attrs and #update_attrs methods instead.

+ +

Returns:

+ + + (Component) + + + + — +
