Question

How do i clamp a camera 2d Node?

i have a camera 2d that moves on the x axis (and x axis only), how would i go and use a clamp function to stop it

2

Can you give me the code used to move it?

extends Camera2D

var isHoveringRight = false
var isHoveringLeft = false

func _process(_delta):
	if isHoveringRight == true:
		position.x += 10
	if isHoveringLeft == true:
		position.x -= 10
	var xclamp = 2403
	
	position.clamp() #thing i need

func _on_navigate_right_body_entered(_body):
	isHoveringRight = true
func _on_navigate_right_body_exited(_body):
	isHoveringRight = false


func _on_navigate_left_body_entered(body):
	isHoveringLeft = true
func _on_navigate_left_body_exited(body):
	isHoveringLeft = false

camera.position.x = clamp(camera.position.x, deg_to_rad(-100), deg_to_rad(100))

That might work but I have not tested it and you may need to remove the camera in camera.position depending on how it’s set up
also change the 100 to whatever you want

(I forgot to add .x to the position as pointed out by the other reply)

I believe you would use position.x.clamp(mapsize min,mapsizemax)

So if your map was say 10000 pixels long, you should be able to do (0, 10000).

If say you run into an issue where it’s clamping but it over extends the boundary you want, subtract half of the camera width from the 10000 and that should do it.

It says "Unexpected identifier in class body :(.

‘Cannot find property “clamp” on base “float”’

something about camera not being declared in the current scope

Edit: so i went and fixed the not declared problem

but know its spits out that position is a null instanse

I am trying to replicate your camera in a new project. Can you show me the scene tree

that button there is not related to the problem im trying to fix

actually never mind about the reply I deleted this is a much better way to use clamp() that I just discovered

position.x = clamp(position.x,deg_to_rad(-xclamp),deg_to_rad(xclamp))

you may want to change the value of xclamp

someone pointed out that Camera2D has built in Limits you can change

You already have camera limit properties.

You can set them up in your scene or if they’re dynamic you can set them via code based on your current map size.
