When node_a and node_b move in different directions the bias controls how fast the joint pulls them back to their original position. The lower the bias the more the two bodies can pull on the joint.
When set to 0, the default value from [member ProjectSettings.physics/2d/solver/default_constraint_bias] is used.
set getbool disable_collision<>():bool set get
If true, the two bodies bound together do not collide with each other.
set getNodePath node_a<>():NodePath set get
Path to the first body (A) attached to the joint. The node must inherit PhysicsBody2D.
set getNodePath node_b<>():NodePath set get
Path to the second body (B) attached to the joint. The node must inherit PhysicsBody2D.
