HingeJoint

Inherits: Joint < Spatial < Node < Object

A hinge between two 3D PhysicsBodies.

Description

A HingeJoint normally uses the Z axis of body A as the hinge axis, another axis can be specified when adding it manually though. See also Generic6DOFJoint.

Enumerations

enum Param:

Param PARAM_BIAS = 0

The speed with which the two bodies get pulled together when they move in different directions.

Param PARAM_LIMIT_UPPER = 1

The maximum rotation. Only active if angular_limit/enable is true.

Param PARAM_LIMIT_LOWER = 2

The minimum rotation. Only active if angular_limit/enable is true.

Param PARAM_LIMIT_BIAS = 3

The speed with which the rotation across the axis perpendicular to the hinge gets corrected.

Param PARAM_LIMIT_SOFTNESS = 4

Param PARAM_LIMIT_RELAXATION = 5

The lower this value, the more the rotation gets slowed down.

Param PARAM_MOTOR_TARGET_VELOCITY = 6

Target speed for the motor.

Param PARAM_MOTOR_MAX_IMPULSE = 7

Maximum acceleration for the motor.

Param PARAM_MAX = 8

Represents the size of the Param enum.


enum Flag:

Flag FLAG_USE_LIMIT = 0

If true, the hinges maximum and minimum rotation, defined by angular_limit/lower and angular_limit/upper has effects.

Flag FLAG_ENABLE_MOTOR = 1

When activated, a motor turns the hinge.

Flag FLAG_MAX = 2

Represents the size of the Flag enum.
