Question
Hey everyobody. I asked this questions in the other Godot Forum and also on stackoverflow, but nobody seems to be able to help me :/
I am currently working on something 2D top down and have a Camera2D node as child in my main scene. I want to clamp my camera position to avoid the “camera sticks to the limit” issue.
Works fine so far. However, if I zoom first and then pan afterwards (everything on mac touchpad). The camera position is jumping to the top left corner.
Limits of the camera are:
left: -100px
right: 2000px
bottom: 1100px
top: -100px
Viewport size: 1920 * 1080
My script is the following:
extends Camera2D
# Zoom settings
var min_zoom = Vector2(1, 1) # Maximum zoom-out level
var max_zoom = Vector2(5, 5) # Maximum zoom-in level
var zoom_speed = 0.5 # Speed of zooming in/out
@onready var viewport_size = get_viewport().size
func _input(event):
if event is InputEventMagnifyGesture or event is InputEventPanGesture:
if event is InputEventMagnifyGesture:
var previous_zoom = zoom
zoom.x += event.factor * zoom_speed - zoom_speed
zoom.y += event.factor * zoom_speed - zoom_speed
zoom.x = clamp(zoom.x, min_zoom.x, max_zoom.x)
zoom.y = clamp(zoom.y, min_zoom.y, max_zoom.y)
# Handle panning with touchpad
if event is InputEventPanGesture:
position -= event.delta * zoom *-1 # Using zoom to scale the pan speed according to the current zoom level
# this works for only panning. but it doesn't work anymore if I zoom first. then it only zooms in the top left corner
clamp_position()
## currently doesn't work properly when zoomed in
func clamp_position():
viewport_size = get_viewport().size
var x = zoom.x*viewport_size.x/2
var y = zoom.y*viewport_size.y/2
position.x = clamp(position.x, limit_left+x, limit_right-x)
position.y = clamp(position.y, limit_top+y, limit_bottom-y)
func _process(delta):
# moving camera with keyboard
var InputX = int(Input.is_action_pressed("ui_right")) - int(Input.is_action_pressed("ui_left"))
var InputY = int(Input.is_action_pressed("ui_down")) - int(Input.is_action_pressed("ui_up"))
position.x = lerp(position.x, position.x + InputX* pan_speed*zoom.x, pan_speed*delta)
position.y = lerp(position.y, position.y + InputY* pan_speed*zoom.y, pan_speed*delta)If anyone could point me to the right direction, that would be nice.
I have searched this forum and reddit, but have not found anything yet.
