HingeJoint3D
继承： Joint3D < Node3D < Node < Object
A physics joint that restricts the rotation of a 3D physics body around an axis relative to another physics body.
描述
A physics joint that restricts the rotation of a 3D physics body around an axis relative to another physics body. For example, Body A can be a StaticBody3D representing a door hinge that a RigidBody3D rotates around.

枚举
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
已弃用： This property is never used by the engine and is kept for compatibility purpose.
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.
属性说明
float angular_limit/bias = 0.3
The speed with which the rotation across the axis perpendicular to the hinge gets corrected.
bool angular_limit/enable = false
If true, the hinges maximum and minimum rotation, defined by angular_limit/lower and angular_limit/upper has effects.
float angular_limit/lower = -1.5708
The minimum rotation. Only active if angular_limit/enable is true.
float angular_limit/relaxation = 1.0
The lower this value, the more the rotation gets slowed down.
float angular_limit/softness = 0.9
已弃用： This property is never set by the engine and is kept for compatibility purposes.
float angular_limit/upper = 1.5708
The maximum rotation. Only active if angular_limit/enable is true.
bool motor/enable = false
When activated, a motor turns the hinge.
float motor/max_impulse = 1.0
Maximum acceleration for the motor.
float motor/target_velocity = 1.0
Target speed for the motor.
float params/bias = 0.3
The speed with which the two bodies get pulled together when they move in different directions.
