FAQ
What is a good approach when implementing DOTS Physics in Unity ECS?
A good way to approach implementing DOTS Physics is by checking out the DOTS Physics samples and finding an example similar to what you're looking to implement, and then copying, pasting, and modifying to your needs. The current Physics documentation is difficult and trying to build these functionalities from scratch is a Sisyphean task. It's much simpler to grab code from Unity's samples since there's a lot of "boilerplate" for a majority of the Physics interactions.
What are the main run-time components of DOTS Physics in Unity ECS?
The main components are: PhysicsCollider, PhysicsVelocity, PhysicsMass, PhysicsDamping, PhysicsGravityFactor, PhysicsCustomTags. These components are read from to BuildPhysicsWorld then written to in ExportPhysicsWorld.
What are Physics Category Names in Unity ECS?
Physics Category Names are how you can define what objects collide with each other and whether or not they raise events.
Haven’t begun learning Unity DOTS yet, and need to start at the very beginning?
If you haven't yet dipped your toes into learning Unity's new multithreaded Data-Oriented Technology Stack (DOTS), now is the time. You can start at the very beginning with Moetsi’s tutorial, which culminates in your very own deployable sample project. You’ll be guided by full workflows, code-alongs, videos, and GIFs along the way.
