Description

The HingeJoint groups together 2 rigid bodies, constraining them to move like connected by a hinge.

This joint is great for, well, doors, but can also be used to model chains, etc...

The HingeJoint has a motor which can be used to make the hinge spin around the joints axis. A spring which attempts to reach for a target angle by spinning around the joints axis. And a limit which constrains the joint angle.

Properties

angleThe current angle in degrees of the joint relative to its rest position. (Read Only)
extendedLimitsIf enabled, the angle of the hinge is extended to [-360, 360] degrees.
limitsLimit of angular rotation (in degrees) on the hinge joint.
motorThe motor will apply a force up to a maximum force to achieve the target velocity in degrees per second.
springThe spring attempts to reach a target angle by adding spring and damping forces.
useAccelerationDefines whether the HingeJoint.spring outputs accelerations instead of forces.
useLimitsEnables the joint's limits. Disabled by default.
useMotorEnables the joint's motor. Disabled by default.
useSpringEnables the joint's spring. Disabled by default.
velocityThe angular velocity of the joint in degrees per second. (Read Only)

Properties

gameObjectThe game object this component is attached to. A component is always attached to a game object.
tagThe tag of this game object.
transformThe Transform attached to this GameObject.
anchorThe Position of the anchor around which the joints motion is constrained.
autoConfigureConnectedAnchorShould the connectedAnchor be calculated automatically?
axisThe Direction of the axis around which the body is constrained.
breakForceThe force that needs to be applied for this joint to break.
breakTorqueThe torque that needs to be applied for this joint to break. To be able to break, a joint must be _Locked_ or _Limited_ on the axis of rotation where the torque is being applied. This means that some joints cannot break, such as an unconstrained Configurable Joint.
connectedAnchorPosition of the anchor relative to the connected Rigidbody.
connectedArticulationBodyA reference to an articulation body this joint connects to.
connectedBodyA reference to another rigidbody this joint connects to.
connectedMassScaleThe scale to apply to the inverse mass and inertia tensor of the connected body prior to solving the constraints.
currentForceThe force applied by the solver to satisfy all constraints.
currentTorqueThe torque applied by the solver to satisfy all constraints.
enableCollisionEnable collision between bodies connected with the joint.
enablePreprocessingToggle preprocessing for this joint.
massScaleThe scale to apply to the inverse mass and inertia tensor of the body prior to solving the constraints.
hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameThe name of the object.
