Friction Joint 2D

The Friction Joint 2D connects GameObjects controlled by Rigidbody 2D physics. The Friction Joint 2D reduces both the linear and angular velocities between the objects to zero (ie, it slows them down).

프로퍼티 기능
Enable Collision Enable this property to enable collisions between the two connected GameObjects.
Connected Rigid Body Specify the other object this joint connects to. Leave this as None to have the other end of the joint fixed at a point in space defined by the Connected Anchor property. Select the circle icon to the right to view a list of GameObjects to connect to.
Auto Configure Connected Anchor Enable this property to automatically set the anchor location for the other object this joint connects to. You do not need to enter coordinates for the Connected Anchor property if you enable this property.
Anchor Define where (in terms of x, y-coordinates on the Rigidbody 2D) the end point of the joint connects to this GameObject.
Connected Anchor Define where (in terms of x, y-coordinates on the Rigidbody 2D) the end point of the joint connects to the other GameObject.
Max Force Set the linear (or straight line) movement between joined GameObjects. A high value resists the linear movement between GameObjects.
Max Torque Set the angular (or rotation) movement between joined GameObjects. A high value resists the rotation movement between GameObjects.
Break Action Set the action taken when either the force or torque threshold is exceeded.
Break Force Set the force threshold which if exceeded, will cause the joint to perform the selected Break Action. The default value is set to Infinity, which can never be exceeded and therefore the Break Action can never be taken while the threshold remains at this value.
Break Torque Set the torque threshold which if exceeded, will cause the joint to perform the selected Break Action. The default value is set to Infinity, which can never be exceeded and therefore the Break Action can never be taken while the threshold remains at this value.

Using this joint

Use the Friction Joint 2D to slow down movement between two points to a stop. This joint’s aim is to maintain a zero relative linear and angular offset between two points. Those two points can be two Rigidbody 2D components or a Rigidbody 2D component and a fixed position in the world. (Connect to a fixed position in the world by setting Connected Rigidbody to None).

Resistance

The joint applies linear force (Force) and angle force (Torque) to both Rigidbody 2D points. It uses a simulated motor that is pre-configured to have a low motor power (and so, low resistance). You can change the resistance to make it weaker or stronger.

강한 저항:

  • A high (1,000,000 is the highest) Max Force creates strong linear resistance. The Rigidbody 2D GameObjects won’t move in a line relative to each other very much.
  • A high (1,000,000 is the highest) Max Torque creates strong angular resistance. The Rigidbody 2D GameObjects won’t move at an angle relative to each other very much.

약한 저항:

  • A low Max Force creates weak linear resistance. The Rigidbody 2D GameObjects move easily in a line relative to each other.
  • A low Max Torque creates weak angular resistance. The Rigidbody 2D GameObjects move easily at an angle relative to each other.

제약

마찰 조인트 2D는 다음 두 개의 제약 사항이 동시에 적용됩니다.

  • 두 개의 리지드바디 2D에서 두 앵커 지점 간 상대 리니어 속도가 0으로 유지되어야 합니다.
  • 두 개의 리지드바디 2D에서 두 앵커 지점 간 상대 각속도가 0으로 유지되어야 합니다.

마찰이 있는 것 같이 물리 게임 오브젝트를 구성하려면 이 조인트를 사용하면 됩니다. 이는 리니어 또는 각 이동에 대해, 또는 둘 다에 대해 저항하도록 설정할 수 있습니다. 아래는 이에 대한 예시입니다.

  • 회전하기는 하지만 적용된 힘에 저항하기 때문에, 플레이어가 움직이는 것이 어렵지만 가능한 플랫폼
  • A ball that resists linear movement. The ball’s friction is related to the GameObject’s velocity and not to any collisions. It acts like the Linear Drag and Angular Drag which is set in Rigidbody 2D. The difference is that Friction Joint 2D has the option of maximum Force and Torque settings.)
