Question

I have a preexisting project that broke when i upgraded and i’m trying to figure out how to do the same thing in the latest version. I simply want a characte to move between a marker to another marker and back again.

I have some really simple code. A tilemap layer with navigation on it, and some without. I want the character to move around the area that does not have navigation and reach point 2.

All it does is goes back and forth and gets stuck.

Any help would be great.

Thanks

extends CharacterBody2D

var navigation_target_name = 'Marker2'
var speed = 50

@onready var nav_agent: NavigationAgent2D = $NavigationAgent2D
@onready var marker_1: Marker2D = $"../Marker1"
@onready var marker_2: Marker2D = $"../Marker2"

func _ready() -> void:
	get_marker_position()
	
func _physics_process(delta: float) -> void:
	
	if nav_agent.is_navigation_finished():
		get_marker_position()
	else:
		var current_agent_position = position
		var next_path_position = nav_agent.get_next_path_position()
		var new_velocity = current_agent_position.direction_to(next_path_position) * speed				
		velocity = new_velocity
		
	move_and_slide()
	
	
func get_marker_position():
	if navigation_target_name == 'Marker1':
		navigation_target_name == 'Marker2'
		nav_agent.target_position = marker_2.position
	else:
		navigation_target_name == 'Marker1'
		nav_agent.target_position = marker_1.position
		
	print('move to ' + navigation_target_name)

Hi Pickles. Are you trying to get it to patrol endlessly between the two markers?

Looks like you’ve got == instead of = on two lines in get_marker_position(). Not sure if that will fix it completely but it’ll definitely help.

navigation_target_name == 'Marker2'

Should be

navigation_target_name = 'Marker2'

Yeah endless patrol between the two markers.

I didnt notice the error but now the characte just wanders around and doesnt travel to the markers.

I have somewhat correct all the issues but the player keeps walking over the non nav areas.
