I am modifying the Godot template for navigation. I want to put a camera that follows the sprite that follows the path. But at the moment I set the camera as "current" navigation begins to fail.

I intend to make a point and click game with side-scrolling.

Thats te node structure:

   |_ path (sprite)
   |_ navpoly
   |_ agent (sprite)

And that's the code ho extends de first node:

extends Navigation2D
# Member variables
const SPEED = 200.0

var begin = Vector2()
var end = Vector2()
var path = []

func _process(delta):
        if (path.size() > 1):
            var to_walk = delta*SPEED
            while(to_walk > 0 and path.size() >= 2):
                var pfrom = path[path.size() - 1]
                var pto = path[path.size() - 2]
                var d = pfrom.distance_to(pto)
                if (d <= to_walk):
                    path.remove(path.size() - 1)
                    to_walk -= d
                    path[path.size() - 1] = pfrom.linear_interpolate(pto, to_walk/d)
                    to_walk = 0

            var atpos = path[path.size() - 1]

            if (path.size() < 2):
                path = []

func _update_path():
    var p = get_simple_path(begin, end, true)
    path = Array(p) # Vector2array too complex to use, convert to regular array


func _input(event):
    if (event.type == InputEvent.MOUSE_BUTTON and event.pressed and event.button_index == 1):
        begin = get_node("agent").get_pos()
        # Mouse to local navigation coordinates
        end = event.pos - get_pos()

func _ready():

it seems the problem is that only recognizes the part that is visible when loading the polygon navigation

What's probably happening is the camera's transform is throwing off the coordinates coming from your click action.

in your _input function, change

end = event.pos - get_pos()


end = get_viewport_transform().affine_inverse().xform( event.global_pos )

If that doesn't work, try using pos vs global_pos, or including your - get_pos() offset.

The getviewporttransform() method works perfectly! Thank you so much.

This works. Syntax has changed since 3.0, global_pos is replaced by global_position :

end = get_viewport_transform().affine_inverse().xform( event.global_position )
