Abstract base class for all joints in 2D physics. 2D joints bind together two physics bodies ([member node_a] and [member node_b]) and apply a constraint.

When [member node_a] and [member node_b] move in different directions the [member bias] controls how fast the joint pulls them back to their original position. The lower the [member bias] the more the two bodies can pull on the joint.

When set to [code]0[/code], the default value from [member ProjectSettings.physics/2d/solver/default_constraint_bias] is used.
