The tide is beginning to shift from this use of deep hierarchies to a variety of methods that compose a game entity object as an aggregation of components. This article explains what this means, and explores some of the benefits and practical considerations of such an approach. I will describe my personal experience in implementing this system on a large code base, including how to sell the idea to other programmers and management. Different games have different requirements as to what is needed in a game entity, but in most games the concept of a game entity is quite similar. Component · Decoupling Patterns · Game Programming Patterns. Game Engine Design – Component Based Entities ← Entropy Interactive. Component based entities are becoming increasingly popular.
They are a design pattern that can greatly improve the maintainability and flexibility of your game code. This tutorial will describe what component based entities are and how to design them. Refactoring The Object System » Legend of Grimrock. Welcome to the first development update of Grimrock 2!
In this post I’m going to talk about a big internal change under the hood of the engine. The discussion should be especially interesting to modders. A small disclaimer before we get started: many things that we talk about in these updates are work in progress, incomplete or ideas that may not have been proven in practice to work.
