Add option to ignore time scale

[seh-GAH-toh]

Project Type

3D, 2D

Feature Description

Add an option for PhantomCamera and/or PhantomCameraHost to ignore Engine.time_scale, preventing camera tweening from freezing/speeding when the engine time scale is modified.

Use Cases

When pausing my game, I set Engine.time_scale to 0, which freezes the game physics processing and stops the player and obstacles from moving. However, it also affects tweening, which prevents my phantom camera from transitioning from the player camera to the pause camera.

Current behavior:

current.mp4

Ideal behavior:

ideal.mp4

(Optional) Proposed Solution

Godot tweens have a method called .set_ignore_time_scale() that allows tweening to ignore time_scale, but Phantom Camera doesn't seem to use it.

From what I can tell, this doesn't appear to be possible right now. The camera tweening system is technically not using the Tween class, but rather methods from the class', specifically Tween.interpolate_value(), that returns the various values (position, rotation, etc.) for the camera to change to. Importantly, that is being called manually from the _process / _physics_process, as opposed to using a delcared variable of type Tween.

As far as I can tell, set_ignore_time_scale() only works on variables of type Tween (and Timer for that matter) classes. So the solution would have to be the PCamHost, and Camera2D/3D, node ignoring Engine.time_scale while it's tweening a camera.

There is a proposal to support that, but it hasn't seen updates in some time now: godotengine/godot-proposals#9068

Thanks for the response,

I discovered that when I tried to implement it myself on #642 , messing with delta gave unpredictable results, it worked with Engine.time_scale values greater than 0, but when time scale is 0, which is my use case, made the tween break.

Thank you for taking a look at this, I will find another way to pause my game, at the moment, the options I have tried kill my objects momentum, but I will get it working somehow, again,thank you very much and have a great day, your plugin is a life saver!
