Question

Hello! Im making a “horse maker” project for fun, and I encountered a problem that has me stumped. I wanted a menu like in spore creature creator that slides in and out, and its mostly good except the zooming doesnt feel quite right when the menu is open

Sadly cant put attachments but basically I use an orthogonal camera that slides to the right when you open the menu, I didnt like the look of perspective camera and I attached mouse wheel to the camera size so I can zoom in and out, obviously because the model is not in the middle of the screen it zooms in its hind which just feels wonky from a players perspective I think. I tried moving the camera with zoom (in z) but it didnt work well, the movement and zoom were obviously unsynched and couldnt get it to work right. Tried changing to perspective, didnt like how it looked. Tried “look at” but it just kind of changed the camera rotation so it looked from above the horse and the zoom worked the same way, which was to be expected.

At this point I dont know if what Im asking is actually impossible and have to give it up, I searched through spore footage and no lightbulbs were lit.

So if someone knows how to replicate the look of the model going to the side to make way for the menu while keeping zoom focused on it itd be great. If you think its impossible, please tell me im losing my mind lol

func _ready() -> void:
    print("hello world")

You can upload the video to streamable.com and post a link here. This will make it much easier to understand the issue.

Also, please make sure to paste your current script here.

Sure, heres my video showcasing the “problem” and my code (albeit its a bit embarassing to share since im so new at this haha):

Your code is not formatted properly, it’s very hard to read in this format. You should put your code between tripple backticks ``` on both sides.

```gdscript
<your code here>
```

Thanks but I actually found a solution, instead of moving the camera Im using a subviewport with a viewport container with clip contents and I move that, thank you anyway!!!
