Joint used with [Skeleton2D] to control and animate other nodes.

|
<description>
|
|
Use a hierarchy of [code]Bone2D[/code] bound to a [Skeleton2D] to control, and animate other [Node2D] nodes.
|
|
You can use [code]Bone2D[/code] and [code]Skeleton2D[/code] nodes to animate 2D meshes created with the Polygon 2D UV editor.
|
|
Each bone has a [member rest] transform that you can reset to with [method apply_rest]. These rest poses are relative to the bone's parent.
|
|
If in the editor, you can set the rest pose of an entire skeleton using a menu option, from the code, you need to iterate over the bones to set their individual rest poses.

<method name="get_autocalculate_length_and_angle" qualifiers="const">

|
|
<description>
|
|
Returns whether this [code]Bone2D[/code] node is going to autocalculate its length and bone angle using its first [code]Bone2D[/code] child node, if one exists. If there are no [code]Bone2D[/code] children, then it cannot autocalculate these values and will print a warning.

<method name="get_bone_angle" qualifiers="const">

|
|
<description>
|
|
Returns the angle of the bone in the [code]Bone2D[/code] node.
|
|
[b]Note:[/b] This is different from the [code]Bone2D[/code]'s rotation. The bone angle is the rotation of the bone shown by the [code]Bone2D[/code] gizmo, and because [code]Bone2D[/code] bones are based on positions, this can vary from the actual rotation of the [code]Bone2D[/code] node.

Returns the node's [member rest] [code]Transform2D[/code] if it doesn't have a parent, or its rest pose relative to its parent.

|
|
When set to [code]true[/code], the [code]Bone2D[/code] node will attempt to automatically calculate the bone angle and length using the first child [code]Bone2D[/code] node, if one exists. If none exist, the [code]Bone2D[/code] cannot automatically calculate these values and will print a warning.

<description>
|
|
Sets the bone angle for the [code]Bone2D[/code] node. This is typically set to the rotation from the [code]Bone2D[/code] node to a child [code]Bone2D[/code] node.
|
|
[b]Note:[/b] This is different from the [code]Bone2D[/code]'s rotation. The bone angle is the rotation of the bone shown by the [code]Bone2D[/code] gizmo, and because [code]Bone2D[/code] bones are based on positions, this can vary from the actual rotation of the [code]Bone2D[/code] node.
