How to use RaycastCommand

RaycastCommand is API that allows multiple raycast requests to be made in jobs. By using RaycastCommand instead of multiple calls to methods like Physics.Raycast(), the time spent on raycasts on the main thread can be reduced. The post contains code samples to demonstrate the comparison between raycasts using Physics.RaycastNonAlloc() and RaycastCommand. The results show the benefits of using RaycastCommand for efficient raycast operations.

How to properly implement movement in Unity 2D: Learn the basis of a proficient platformer controller

Games such as Super Meat Boy, Celeste, The King’s Bird, and Dead Cells represent the gold standard for 2D movement mechanics. These games have achieved this status by creating satisfying and intuitive movement mechanics that are centered around simple directional movement and satisfying jumps. They are excellent platformers because they use a variety of invisible tricks in their physics systems to create the illusion of tight controls. These tricks are crucial in ensuring that the player’s movements feel natural and responsive enhancing the overall gameplay experience.

CI/CD pipeline Unity Part 3

We’ll look at the following options:
- Improving the stability of main by enforcing PRs are up to date before merging.
- Caching to speed up job runs
- Separation and Parallelisation of Jobs
- Ensuring your main branch only contains conventional commit messages
- Self-Hosted Runners and Cache Accelerators
- Only testing code changes

NSprites: Unity DOTS Sprite Rendering Package

This framework provides sprite rendering system compatible with Entities package (unity ECS).
Basically it sync whatever entity component you want with GPU data to perform instanced rendering. As a result all entities with same Material can be rendered with single drawcall.

How it works
SpriteRenderingSystem sync registered entity components with ComputeBuffers to send data to GPU and then renders entities with Graphics.DrawMeshInstancedProcedural. System also controls how ComputeBuffers reallocates if capacity exceeds. Sprites are simple entities with no limits of what components you use.

Randomation Vehicle Physics
This is a vehicle physics system for the Unity engine, originally developed with Unity 5.6. The most recent Unity version it has been tested with is 2019.2.9. It aims to achieve semi-realistic, general-purpose driving mechanics. This was originally sold on the asset store as Randomation Vehicle Physics 2.0.
