Error when enabling 'show viewfinder in play'

[kresnadialbaihaqi]

My game crashes whenever I enable the show viewfinder in play. It runs fine if I turn the show viewfinder off.
Godot said that get_camera_rid is a nonexistent function. It was in the viewfinder.gd, line 419.
Console output:

0:00:02:483   _set_viewfinder_camera: Invalid call. Nonexistent function 'get_camera_rid' in base 'Nil'.
<GDScript Source>viewfinder.gd:419 @ _set_viewfinder_camera()

I already updated it to 0.10, but it still didn't fix it.

What is your Godot version if you don't mind me asking?

[kresnadialbaihaqi]

I'm using Godot 4.5.1

[Mustfa-IT]

What is your scene setup?

[kresnadialbaihaqi]

I'm making a 2D side-scroll game, if that's what you mean by setup.
Which is weird because the error code is mentioning camera_3d, which I didn't even use.

@kresnadialbaihaqi how did you install the plugin? from the asset store?

I do have a Node2D as the parent of my camera stuff.

I'm assuming you're instantiating this inside a scene? The viewfinder is looking at the root node of the active scene tree.
In the editor, it's the root node of the active tab you have open, and at runtime it's whatever the first scene node in the Remote subtab (inside the Scene tab in the editor) that is used.

If you run the Framed Follow example scene from addons/phantom_camera/examples/2D/2d_follow_framed_example_scene.tscn you should be able to see the root node as the output as Root:<Node2D#40332428672> if you kept the print log above. If not, then it might imply it's something either in the editor itself or something else entirely.

I tried to open the example scene, but it has the same exact problem. The nonexistent get_camera_rid function.
This is weird. I think I messed up somewhere, but I really never touch any scripts related to Phantom Camera. I'm so confused right now.

Btw, you don't have to reply anymore. I think this is more like a me problem. I'm going to troubleshoot it somehow.
Thank you so much for your help! And I'm really, really sorry for taking up your time.

Oh no, generally speaking, if someone reports an issue, it's likely not an isolated incident; only a minority bother reporting problems all in all. So always appreciate knowing when someone encounters something unexpected. For me, it's useful to figure out if there are specific combinations of things in a given project + addon that are the root of the issue.

Without direct access to your project, the last suggestions I have are to create a fresh Godot project, download the addon and test the example scene like above. If that produces the issue still, then it's likely something to do with either Godot on your machine or a hardware-specific problem. If so:

1. Worth checking to see if there are GPU driver updates if you're on Windows or Linux, as that has been a culprit in a very few instances.
2. Also be worth trying to run the project in Godot 4.6 RC; obviously, use version control in case something were to break. Someone had a crash issue the other day, and that appeared to be resolved in Godot 4.6; no idea why.

[kresnadialbaihaqi]

I tried your suggestion to update my GPU driver, and also tried it in Godot 4.6 RC, but it's still giving me the same error. However, I duplicated the project, and I deleted all of the scenes and scripts, except the Phantom Camera add-on, so it leaves me with just a simple 2D side-scroll scene with just a CharacterBody2D and the camera stuff. It fixes the problem, so it's definitely something that I made that causes the problem.

I haven't found which component, but I will try to duplicate the project and brute-force-troubleshoot it by deleting components one by one and keep testing the show viewfinder in play.

I'm really sorry about this. Turns out it was indeed just me who somehow broke Phantom Camera.
Thank you so much for the support! I'll give an update once I fix it.

No problem! Hope it's a simple fix in the end 🙂
