wave5-physics-velocity-force-application

What problem does it solve?

This Skill helps you apply forces and impulses in Unity DOTS Physics correctly by updating PhysicsVelocity at the right time relative to the physics simulation.

Core Features & Use Cases

• Fixed-step force application: Write PhysicsVelocity from systems in FixedStepSimulationSystemGroup before PhysicsSystemGroup to keep results stable.
• Dynamic-body safe updates: Prevent NaNs and invalid motion by guarding static/infinite-mass bodies using PhysicsMass.InverseMass.
• Impulse and continuous behaviors: Use the pattern for gravity-well style continuous forces, wind/magnetic attraction, and one-shot initial velocity assignment after spawning.

Quick Start

Tell the AI to write a Burst ISystem scheduled in FixedStepSimulationSystemGroup that updates PhysicsVelocity before PhysicsSystemGroup to apply a continuous directional force while guarding against PhysicsMass.InverseMass == 0.
