When [member node_a] and [member node_b] move in different directions the [code]bias[/code] controls how fast the joint pulls them back to their original position. The lower the [code]bias[/code] 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.
