Vector2 Rotation?

[ComiCross]

4.3

I’m trying to set the rotation of another node to be the same as another node, and this is the code I have for that:

func _physics_process(delta):
	$Arm1/Node2D.global_rotation = Vector2(sword.global_rotation)
	$Arm2/Node2D.global_rotation = Vector2(sword.global_rotation)

But when I try to run it it says that it’s an “Invalid call” and it’s a “Nonexistent ‘Vector2’ constructor.”

Is there a way to set rotation of two nodes to be the same, and do you use Vector2 to do it?

[godotuser6000]

Why do you create a new Vector2?

sword.global_rotation should already be a Vector2 => you can set it directly, right?

[ComiCross]

I took out the Vector2, which runs the code now, but I now realize that I think what I really need is for the $Arm2/Node2D to have the opposite rotation as sword, which I also don’t know how to do

[gertkeno]

Could you do this? Using the negative operator

$Arm1/Node2D.rotation = -sword.rotation
$Arm2/Node2D.rotation = -sword.rotation

I had to change a couple other things in the code, but that worked, thanks!

One more question though, is there a way to only keep the x rotation?

[gertkeno]

There is no ‘x’ rotation in 2D. Maybe you intend to flip the sprite?

[ComiCross]

Yeah flip the whole node, the only problem though (which I could live with if it it’s unfixable) is that when it’s rotated up, it gets rotated down and vice versa.
