Hey!,I'm making a Top Down game and I'm struggling with the enemy ai.
I watched some tutorials and at last I took the code from the nav demo.
I changed the "end" to the player's position but when I press the key I have assigned ,it gets the position that the player was placed in the scene and won't update it anyhow I tried.

Thanks in advance!

Here's the code:

extends Navigation2D


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
            else:
                path[path.size() - 1] = pfrom.linear_interpolate(pto, to_walk/d)
                to_walk = 0

        var atpos = path[path.size() - 1]
        get_node("/root/World/Enemy").set_pos(atpos)

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


func _update_path():
    var p = get_simple_path(begin, end, true)
    path = Array(p) 
    path.invert()

    set_process(true) 


func _input(event):
    if (Input.is_action_pressed("test2")): 
        begin = get_node("/root/World/Enemy").get_pos()
        end = get_node("/root/World/player").get_pos()
        _update_path()


func _ready():
    set_process_input(true)

I changed original post to show better codes.

Looks like you are trying to get the enemy to move towards the player? What exactly is happening? Is the enemy just staying in position? Should be easy enough to debug if you just step through the code. Is atpos being updated how you expect it to be?
