AdaptorPhysX

中文

AdaptorPhysX project try to use CPU mutil threading(Unity Burst & Jobs system) implement PBD (Position Based Dynamics) algorithm to simulate a deformable object(rope, cloth, softbody, fluid) with volume or surface, and implement a calculation framework according to PBD calculation rules. You can complete your own algorithm expansion based on this project.

Require

Require unity ECS architecture. (Entities is not necessary), plz

Windows – Package Manager – Add package from git URL - input: com.unity.jobs

• com.unity.burst - 1.8.9
• com.unity.jobs - 0.70.0-preview.7
• com.unity.mathematics - 1.2.6

Unity

In version 2022.3.13, there is a Bug in the display of schemas in Unity, which causes the Constraint to not operate properly in Inspector, so you can only wait for the official Unity update.
