PinJoint2D

继承： Joint2D < Node2D < CanvasItem < Node < Object

A physics joint that attaches two 2D physics bodies at a single point, allowing them to freely rotate.

描述

A physics joint that attaches two 2D physics bodies at a single point, allowing them to freely rotate. For example, a RigidBody2D can be attached to a StaticBody2D to create a pendulum or a seesaw.

属性

属性说明

bool angular_limit_enabled = false

• void set_angular_limit_enabled ( value: bool )
• bool is_angular_limit_enabled ( )

If true, the pin maximum and minimum rotation, defined by angular_limit_lower and angular_limit_upper are applied.

float angular_limit_lower = 0.0

• void set_angular_limit_lower ( value: float )
• float get_angular_limit_lower ( )

The minimum rotation. Only active if angular_limit_enabled is true.

float angular_limit_upper = 0.0

• void set_angular_limit_upper ( value: float )
• float get_angular_limit_upper ( )

The maximum rotation. Only active if angular_limit_enabled is true.

bool motor_enabled = false

• void set_motor_enabled ( value: bool )
• bool is_motor_enabled ( )

When activated, a motor turns the pin.

float motor_target_velocity = 0.0

• void set_motor_target_velocity ( value: float )
• float get_motor_target_velocity ( )

Target speed for the motor. In radians per second.

float softness = 0.0

• void set_softness ( value: float )
• float get_softness ( )

The higher this value, the more the bond to the pinned partner can flex.
