We'll walk through some of the basic ideas behind a first person or FPS controller, including the basic math that gets it going as well as some more subtle tricks like head bobbing and focus locking to make it feel more natural and smooth.

What we'll cover:
* Three.js FirstPersonControls, how to use these in a project
* Using Quaternions and Vector translations to create simple first person camera movement
* Using sin waves and focus locking to improve the overall feeling and give it a more organic experience.

Full source code for the project is available, so if you're interested in fiddling with the code, screwing around with it, or improving it.

Follow me on: Twitter: https://twitter.com/iced_coffee_dev Github: https://github.com/simondevyoutube/ In this project were covering spatial hash grids, or spatial hashing, people seem to call it all sorts of different names. Anyway, well be covering a spatial hash grid implementation in JavaScript, working through it line by line. Well walk through the code step by step, explaining it as we go, and as an added bonus, Ive implemented a small scene in Three.js with hundreds of moving agents that we can use to visualize whats visible from the perspective of any given agent. Ill also tell a small but interesting little story from way back when I was working on xbox/playstation games. Somewhat related to the topic. Having a comprehensive understanding of data structures is fundamental to being a solid game developer. You need to understand the trade-offs, not just in time complexity. Questions like memory consumption, implementation and on-going maintenance costs, these all factor in. Sometimes simple solutions, implemented well, that get you 95% of the way there but at a fraction of the developer cost, are the way to go. The three.js library is available in JavaScript for cross-browser 3d graphics, wrapping webgl and making high level functionality available in the web browser. It’s an extremely mature and well maintained library that I use for many of these videos. In the video, we cover: * What problem are we trying to solve? Well look at examples from major games to understand their needs in different situations. * Well touch on alternative spatial data structures, and discuss the tradeoffs. * Ill talk about an instance in my career thats relevant to this problem * Step by step walk through for the full implementation of a basic spatial hash grid.$
