A physics joint that restricts the movement of two 2D physics bodies to a fixed axis.
描述
A physics joint that restricts the movement of two 2D physics bodies to a fixed axis. For example, a StaticBody2D
representing a piston base can be attached to a RigidBody2D
representing the piston head, moving up and down.
属性
属性说明
float
initial_offset = 25.0
The body B's initial anchor position defined by the joint's origin and a local offset initial_offset
along the joint's Y axis (along the groove).
float
length = 50.0
The groove's length. The groove is from the joint's origin towards length
along the joint's local Y axis.
