abstract class Scar::Object

Overview

Base class for OOP based Entities

An object has the same methods as a system: #init, #update and #render, so all the behaviour and data can be in the same place. You can still add components like with a normal entity though.

You do not need to implement the #render method to draw something, you can also just use regular drawable components or include Scar::Drawable (see Drawable documentation).
