Trying out new Unity API: BatchRendererGroup

The goal of this post is to look at the new BatchRendererGroup API (BRG) and implement the minimal BRG example, so it is easier to understand how to work with it. Then gradually add more complex functionality. In the end we would have a boids simulation rendered using BRG.

unity-footprints: Real-Time Locomotion on Soft Grounds with Dynamic Footprints

The system takes a rigged mesh with kinematic animations and an IK system applied to the feet bones, and with a rigid body for balance control and collision processing. Then it builds a real-time locomotion model that combines a global controller to adjust the overall character pose based on the ground slope with tilting and balancing behaviors, and the IK system to adapt the model to non-flat terrains.

Unity-Http-Debugger: Http request logging tool for Unity.
- Send http requests from Editor Window
- Save requests and responses
Log http requests

We are using a somewhat similar tool to log all requests, which comes very handy for debugging. Much easier than running Charles or another similar tool, with less functionality of course.

Generating procedural terrains with decimated meshes

MeshData API is used here which allows to increase speed of mesh generation/modification significantly.

How To Write A Custom URP Shader With DOTS Instancing Support

I wanted to enhance the look of my boids BatchRendererGroup sample with more suitable meshes instead of cubes. For that I decided to use a custom shader with some simple procedural vertex animation. Without proper documentation available it took me quite a while to figure out how to add DOTS instancing support to it, since it's required for BRG. So I am sharing the solution so you don’t have to spend your time.

Game Maths — Dot Product

Personally I don't implement stuff that requires deep math knowledge in a day-to-day work, but once in a while every game developer faces tasks when you wish you knew the math. And this task could be solved faster and without dirty workarounds if you knew the math behind the required functionality. This post gives one example of a dot product usage, but I liked more another old article on this topic, which I will share here next. So check out both to get better understanding.
