Abstract base class for all 2D physics joints.
Abstract base class for all joints in 2D physics. 2D joints bind together two physics bodies and apply a constraint.
- 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.
- If [code]true[/code], [member node_a] and [member node_b] can not collide.
- The first body attached to the joint. Must derive from [PhysicsBody2D].
- The second body attached to the joint. Must derive from [PhysicsBody2D].
