I am trying to make my character look but I can't fix this error.

bruh

I was trying to make my character look around, but I keep on getting this error called

"Invalid get index 'rotation_degrees' (on base: 'Camera').".

Welcome to the forums @bruh!

Hmm, not sure right off what would be causing the issue. Can you share the code snippet where this error occurs?

bruh

I fixed the issue but then another one occurred right after.

Invalid get index 'rotation_degrees' (on base: null instance)

I will hazard to guess you are calling the function that sets the camera's rotation before _ready is called on the character.

The ready keyword is called after a node has been added to a scene tree and after all the child node _ready calls. If you are setting the camera rotation before adding your character to the scene tree you will have the problem you are seeing.

I would recommend you debug the situation by making a _ready function for your character and having it print out your camera property's name. This means you know that the camera property is non zero and that the character is in the scene tree.

Also add a print statement for the function that sets the camera's rotation. (or set a break point)

I suspect that the camera rotation setting function will be called before the character's ready() function, so you will see the camera rotating function print first (or the break point hit) and not see character.ready() print out its text.

How do I do that? can you send me the code to do it please.

Something like this should work:

func _ready():
	print ("Camera node is: ", camera.name)

# In your function where you are getting the error, you
# can add a condition to see if the camera is null
# (I'm just using "example" here for illustrative purposes)
func example():
	if (camera == null):
		# get the camera
		camera = get_node("Camera")
	# then adjust the rotation degrees, etc

bruh, the reason I didn't answer in particular is that placing a print statement in, and adding a function like:

func _ready(): ...

is basic programming.

Please spend some time learning gdscript and a little coding.

I was suggesting a away to tease out the problem you are having which is like initialization order related. Simply put I think you are calling the function to adjust the camera by the mouse before your character is in the scene tree or the camera is added as a child to the character.
