Inherits: RigidBody2D < PhysicsBody2D < CollisionObject2D < Node2D < CanvasItem < Node < Object

A 2D node that can be used for physically aware bones in 2D.

Description

The PhysicalBone2D node is a RigidBody2D-based node that can be used to make Bone2D nodes in a Skeleton2D react to physics. This node is very similar to the PhysicalBone3D node, just for 2D instead of 3D.

Note: To have the Bone2D nodes visually follow the PhysicalBone2D node, use a SkeletonModification2DPhysicalBones modification on the Skeleton2D node with the Bone2D nodes.

Note: The PhysicalBone2D node does not automatically create a Joint2D node to keep PhysicalBone2D nodes together. You will need to create these manually. For most cases, you want to use a PinJoint2D node. The PhysicalBone2D node can automatically configure the Joint2D node once it's been created as a child node.

Property Descriptions

bool auto_configure_joint = true

  • void set_auto_configure_joint ( bool value )

  • bool get_auto_configure_joint ( )

If true, the PhysicalBone2D node will automatically configure the first Joint2D child node. The automatic configuration is limited to setting up the node properties and positioning the Joint2D.

int bone2d_index = -1

  • void set_bone2d_index ( int value )

  • int get_bone2d_index ( )

The index of the Bone2D node that this PhysicalBone2D node is supposed to be simulating.

NodePath bone2d_nodepath = NodePath("")

The NodePath to the Bone2D node that this PhysicalBone2D node is supposed to be simulating.

bool follow_bone_when_simulating = false

  • void set_follow_bone_when_simulating ( bool value )

  • bool get_follow_bone_when_simulating ( )

If true, the PhysicalBone2D will keep the transform of the bone it is bound to when simulating physics.

bool simulate_physics = false

  • void set_simulate_physics ( bool value )

  • bool get_simulate_physics ( )

If true, the PhysicalBone2D will start simulating using physics. If false, the PhysicalBone2D will follow the transform of the Bone2D node.

Note: To have the Bone2D nodes visually follow the PhysicalBone2D node, use a SkeletonModification2DPhysicalBones modification on the Skeleton2D node with the Bone2D nodes.

Method Descriptions

Joint2D get_joint ( ) const

Returns the first Joint2D child node, if one exists. This is mainly a helper function to make it easier to get the Joint2D that the PhysicalBone2D is autoconfiguring.

bool is_simulating_physics ( ) const

Returns a boolean that indicates whether the PhysicalBone2D node is running and simulating using the Godot 2D physics engine. When true, the PhysicalBone2D node is using physics.
