Trying to create buttons to switch between 4 cameras

[dragatan]

Godot Version 4.4

Hello! I’m trying to create 4 buttons that switch to their assigned cameras when clicked. Currently whenever I click one of those buttons the game crashes. I have the scene with the buttons (Switcher) in the scene with all 4 cameras (Whole Game). The script I have attached to the Switcher is this:

func _on_window_pressed() -> void:
	$WindowCam.current = true
	$CookCam.current = false
	$DrinkCam.current = false
	$AssCam.current = false

func _on_cook_pressed() -> void:
	$WindowCam.current = false
	$CookCam.current = true
	$DrinkCam.current = false
	$AssCam.current = false

func _on_drinks_pressed() -> void:
	$WindowCam.current = false
	$CookCam.current = false
	$DrinkCam.current = true
	$AssCam.current = false

func _on_assemble_pressed() -> void:
	$WindowCam.current = false
	$CookCam.current = false
	$DrinkCam.current = false
	$AssCam.current = true

Any help is appreciated! I am very new to this.

What is the error you recieve?

make sure to format your code pastes between three back ticks ```

Make it easier for new users to format and preview code in their posts

Posting here so to be linked for later use instead of re-typing this every time Make sure you paste scripts instead of screenshots. To properly format pasted code use three ticks ``` at the start and end of your paste like so: ``` # type or paste code here func _ready() -> void:     print("My ready function!") ``` Results in: # type or paste code here func _ready() -> void: print("My ready function!") Press the </> button or ctrl+e in the forum to create these ticks. [2024-09-02…

You do not have to write
Camera3D.current = false

So only need this:

func _on_window_pressed() → void:
    $WindowCam.current = true

func _on_cook_pressed() → void:
    $CookCam.current = true

func _on_drinks_pressed() → void:
    $DrinkCam.current = true

func _on_assemble_pressed() → void:
    $AssCam.current = true

No idea why your game crashes, the code seems fine to me.

Thank you for the format advice, didn’t know how to do that.

This is the error I got:

“Invalid assignment of property or key ‘current’ with value of type ‘bool’ on a base object of type ‘null instance’.”

[dragatan]

I’ve tried writing that, I wrote everything else as false because it wasn’t working. I think the issue is something else though so I’ll delete all the false statements

One of your node paths (or all of them) is wrong. Show your scene structure.

[dragatan]

This is my scene tree

[normalized]

So yeah, your node paths are wrong as those cams are not Switcher’s children. The correct path to a sibling would be $“../Name”

[dragatan]

ok so I tried replacing the $Camera with $“../Camera” and still had the same issue. I parented the cameras to the switcher, using $Camera and that also didn’t do anything

[normalized]

print(self.get_path()) in those functions.

[dragatan]

I’m not exactly sure what you mean by this

[normalized]

func _on_window_pressed() -> void:
	print(self.get_path())
	$WindowCam.current = true
	$CookCam.current = false
	$DrinkCam.current = false
	$AssCam.current = false

[dragatan]

I FIXED IT! I used the set_current_camera($Cam) instead of $cam.current

this is what my final code looks like

extends Control

func _on_window_pressed() -> void:
	set_current_camera($"../WindowCam")

func _on_cook_pressed() -> void:
	set_current_camera($"../CookCam")

func _on_drinks_pressed() -> void:
	set_current_camera($"../DrinkCam")

func _on_assemble_pressed() -> void:
	set_current_camera($"../AssCam")

func set_current_camera(new_camera: Camera2D) -> void:
	$"../WindowCam".enabled = false
	$"../CookCam".enabled = false
	$"../DrinkCam".enabled = false
	$"../AssCam".enabled = false
	new_camera.enabled = true

Thank you all for the help!

If you manually set a camera’s Current property to false, another camera will try to become the current one automatically, so you should instead just use the make_current() method on whichever camera you are trying to switch to.

If this does not solve the issue, can you post the exact error you are seeing and the Node Hierarchy?
