I used Eclipse but IntelliJ Idea is another popular choice, too. There are also a few prerequisites for mod development: You need to install Java 8 and a Forge-compatible IDE. But for testing purposes, such as testing this Minecraft mod, it will do the trick! Take a look at our guide to JWTs for more details.įor editing the HTML page that we use to talk to High Fidelity's Spatial Audio API, any text editor with syntax highlighting will do (For example: VSCode, Notepad++, or Geany). Just a heads up: You should never use a test JWT for production applications. I later used the development console for this space to create a test JWT (authentication token), which I could then use to connect to the audio space. Once I created my account, I logged in and created a new app and audio space. Prerequisitesīefore we dove into building the Minecraft mod, I had to create a High Fidelity developer account. The Minecraft mod is open source and you can view the source code here. Nevertheless, we hope you enjoy learning how we made this Minecraft mod and that it is fun to hack on!

And the result, I'll admit, is by no means perfect. Most importantly for us is that we don't have to worry about having a high additional CPU cost on our local client, and High Fidelity's JavaScript Client Library is easy to use.Īt this point you may be wondering: “Wait, but isn't Minecraft written in Java, not JavaScript?” And you would be 100 percent correct! For this reason, we have to use a few special techniques to get this mod to work. It is also good at handling lots of sounds at once. The API uses HRTF and other techniques to mix sounds in a realistic way that allows you to distinctly hear sounds from different directions while wearing ordinary headphones. I'm going to show you how we made a Minecraft Forge mod to add in-game spatialized voice chat using High Fidelity's Spatial Audio API. But alas, using more sophisticated sound mixing comes with a nontrivial CPU cost. Depending on what functionality is used, you can produce a realistic soundscape. An OpenAL implementation can be much more sophisticated than just a “one dimensional” sound engine. Minecraft: Java Edition actually uses an implementation of OpenAL for its sound engine. If the sound is farther away, then it will be quieter. If the sound is on the right side of you, the sound in your right ear will be louder, and if the sound is on the left side of you, the sound in your left ear will be louder. One rather simple way to implement a sound engine in a game is to determine if a sound is on your right or on your left. Have you ever gone mining underground and heard a zombie groaning from behind the cave walls, but couldn't tell if the zombie was in front of you or behind you? Perhaps you've installed a mod like Dynamic Surroundings to add a more immersive biome soundscape to your world.
