Abstract base class for all 3D physics joints.

Description

Abstract base class for all joints in 3D physics. 3D joints bind together two physics bodies (node_a and node_b) and apply a constraint. If only one body is defined, it is attached to a fixed StaticBody3D without collision shapes.

Property Descriptions

bool exclude_nodes_from_collision = true 🔗

• void set_exclude_nodes_from_collision\ (\ value: bool\ )
• bool get_exclude_nodes_from_collision\ (\ )

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

---

NodePath node_a = NodePath("") 🔗

• void set_node_a\ (\ value: NodePath\ )
• NodePath get_node_a\ (\ )

Path to the first node (A) attached to the joint. The node must inherit PhysicsBody3D.

If left empty and node_b is set, the body is attached to a fixed StaticBody3D without collision shapes.

---

NodePath node_b = NodePath("") 🔗

• void set_node_b\ (\ value: NodePath\ )
• NodePath get_node_b\ (\ )

Path to the second node (B) attached to the joint. The node must inherit PhysicsBody3D.

If left empty and node_a is set, the body is attached to a fixed StaticBody3D without collision shapes.

---

int solver_priority = 1 🔗

• void set_solver_priority\ (\ value: int\ )
• int get_solver_priority\ (\ )

The priority used to define which solver is executed first for multiple joints. The lower the value, the higher the priority.

Method Descriptions

RID get_rid\ (\ ) const 🔗

Returns the joint's internal RID from the PhysicsServer3D.
