[Unity] Rigidbody rigid body

introduce

Rigidbody is the API of rigid body components. By calling related methods, objects have physical characteristics.

Rigid body properties

• Mass 默认值1quality
• Drag 默认值0air resistance
• Angular Drag 默认值0.05Affects the amount of air resistance the object has when rotating it according to the torque.
• Use Gravity 默认值truewhether to use gravity
• IsKinemticIf this option is enabled, the object will not be driven by the physics engine, it can only 变换 (Transform)be manipulated by the .
• InterpalateOnly try one of the provided options if you see jerks in rigid body motion
  • None 默认值Defaults
  • InterpalateSmooth transitions based on the previous frame's transition
  • ExtrapalateSmooth the transform based on the estimated transform for the next frame
• Collision DetectionCollision Detection Algorithm
  • Discrete 默认值Use discrete collision detection for all other colliders in the scene.
  • Continuous
  • Continuous DynamicFor all other colliders, discrete collision detection is used. for fast moving objects
  • Continuous SpeculativeThis method is usually less expensive than sweep-based continuous collision detection
• ConstrainsLimit movement and rotation of objects on some axes
  • Freeze Positionrestricted movement
  • Freeze Rotationlimited rotation
