Remarks

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

Properties

bias

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 physics/2d/solver/default_constraint_bias is used.

var bias : float = 0.0

Property Value

float

Remarks

• void set_bias(float value)
• float get_bias

disable_collision

If true, the two bodies bound together do not collide with each other.

var disable_collision : bool = true

Property Value

bool

Remarks

• void set_exclude_nodes_from_collision(bool value)
• bool get_exclude_nodes_from_collision

node_a

Path to the first body (A) attached to the joint. The node must inherit PhysicsBody2D.

var node_a : NodePath = NodePath("")

Property Value

NodePath

Remarks

• void set_node_a(NodePath value)
• NodePath get_node_a

node_b

Path to the second body (B) attached to the joint. The node must inherit PhysicsBody2D.

var node_b : NodePath = NodePath("")

Property Value

NodePath

Remarks

• void set_node_b(NodePath value)
• NodePath get_node_b

Methods

get_rid

Qualifiers: const

Returns the joint's internal RID from the PhysicsServer2D.
