Question

Is there a way to calculate radians to seconds?

I have a camera parented to a Node3D that is rotating. The camera is rotating around an animated character for a presentation ‘turnaround’ demo.

The character animation is a 6 second loop.

I want the camera rotation to do one full rotation in 6, 12, 18, or 24 (etc) seconds so that a screencapture video can be made to loop.

Does that make sense?
(Thanks)

Here is my current code -

extends Node3D


@export var camera_rotation = 0.002

# Called when the node enters the scene tree for the first time.
func _ready():
	pass # Replace with function body.


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
	rotate_y(camera_rotation)

Here is a web page of my project with a video screencapture on it

delta is the time between frames, so if you multiply your value by delta it becomes “per second” Otherwise it’s “per frame” which isn’t a useful measure of time.

extends Marker3D
@export var meters_per_second = 14

func _process(delta: float) -> void:
    position.z += meters_per_second * delta

This sample would travel at 14m/s because it is 14 * delta.

A full rotation in radians is TAU so if you want a full rotation over the course of a second you would use TAU * delta. If you want a full rotation over the course of 6 seconds you need to divide by 6, TAU * delta / 6

Thanks so much @gertkeno

Yes, oops, forgot ‘delta’. I have a basic understanding of coding so thanks for the lesson in TAU and rotation. It works great. I used

func _process(delta: float) -> void:
	rotate_y(TAU * delta / 8)
