HingeJoint

Inherits: Joint < Spatial < Node < Object

A hinge between two 3D bodies.

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.

Methods

bool get_flag ( Flag flag ) const
float get_param ( Param param ) const
void set_flag ( Flag flag, bool enabled )
void set_param ( Param param, float value )

Enumerations

enum Param:

  • PARAM_BIAS = 0 --- The speed with which the two bodies get pulled together when they move in different directions.
  • PARAM_LIMIT_UPPER = 1 --- The maximum rotation. Only active if angular_limit/enable is true.
  • PARAM_LIMIT_LOWER = 2 --- The minimum rotation. Only active if angular_limit/enable is true.
  • PARAM_LIMIT_BIAS = 3 --- The speed with which the rotation across the axis perpendicular to the hinge gets corrected.
  • PARAM_LIMIT_SOFTNESS = 4
  • PARAM_LIMIT_RELAXATION = 5 --- The lower this value, the more the rotation gets slowed down.
  • PARAM_MOTOR_TARGET_VELOCITY = 6 --- Target speed for the motor.
  • PARAM_MOTOR_MAX_IMPULSE = 7 --- Maximum acceleration for the motor.
  • PARAM_MAX = 8 --- Represents the size of the Param enum.

enum 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_ENABLE_MOTOR = 1 --- When activated, a motor turns the hinge.
  • FLAG_MAX = 2 --- Represents the size of the Flag enum.

Property Descriptions

  • float angular_limit/bias
Default 0.3
Setter set_param(value)
Getter get_param()

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


  • bool angular_limit/enable
Default false
Setter set_flag(value)
Getter get_flag()

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


  • float angular_limit/lower
Default -90.0

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


  • float angular_limit/relaxation
Default 1.0
Setter set_param(value)
Getter get_param()

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

Default 0.9
Setter set_param(value)
Getter get_param()

  • float angular_limit/upper
Default 90.0

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


Default false
Setter set_flag(value)
Getter get_flag()

When activated, a motor turns the hinge.


  • float motor/max_impulse
Default 1.0
Setter set_param(value)
Getter get_param()

Maximum acceleration for the motor.


  • float motor/target_velocity
Default 1.0
Setter set_param(value)
Getter get_param()

Target speed for the motor.


Default 0.3
Setter set_param(value)
Getter get_param()

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