When running my game, the sword blade is facing up, and I need the sword to rotate against its local z axis based on the “ui_left”, “ui_right”, “ui_down” and “ui_up” vector, like so: I can use rotate_object_local(Vector3.BACK, radians) to rotate it about the local z axis, but the angle provided needs to be a relative value, whereas the direction I get from direction.angle() is absolute. How do I rotate the sword around its local axis when I have an absolute angle value?
Node3D’s rotation() and rotation_degree() methods allow you to rotate your sword by an absolute value.
Example:
func _process(delta: float) -> void:
if Input.is_action_just_pressed("ui_left"):
$Sword.rotation_degrees.z = 170
if Input.is_action_just_pressed("ui_right"):
$Sword.rotation_degrees.z = 10
if Input.is_action_just_pressed("ui_up"):
$Sword.rotation_degrees.z = 70
if Input.is_action_just_pressed("ui_down"):
$Sword.rotation_degrees.z = -70
I need the sword to rotate around its local axis, not the global axis.
For example, here’s what the sword rotating around the y axis looks like: -|-------
-|--
+
---|-
-------|-
It works up until the point when I move or transform the sword somewhere else.
This is what that looks like:
/
/
/
-/<
|
|
|
-+<
|
\
\
\
-\<
What I want however, is the sword rotating around it’s local axis, just like I can use transform.basis to get the local x, y and z directions.
you can make your sword node the child of another node3d called Pivot in this case. This node is used to move the weapon in global space, while the sword node is moved in its local space with rotation().

-> Sword
Example:
func _process(delta: float) -> void:
if Input.is_action_just_pressed("ui_left"):
$Pivot/Sword.rotation_degrees.z = 170

It’s a bit unintuitive but it works. I still run into issues with rotation sometimes though.
