[GODOT 4.1] .gd file bar not appearing in area2d's inspector tab

SuperGibaLogan

xyz i see, but the tutorial im using is the only tutorial i could find that does all the gameplay mechanics perfectly
also i typed the code, not copy and paste it (my code isnt fininshed yet just so you know)

SuperGibaLogan

SuperGibaLogan also i did some edits to the code, thats why it looks a little different

SuperGibaLogan

xyz ill look forward into the engine docs

SuperGibaLogan

SuperGibaLogan im currently thinking of ways on how to fix the errors, im also looking at the errors listed in the syntax to think of ways to fix the errors, also, would it be ok if i could show the entire code and also show the errors listed?

xyz

SuperGibaLogan would it be ok if i could show the entire code and also show the errors listed?

Of course. You should have done that right away.

At this point you shouldn't really worry about gameplay mechanics. Learn the programming basics first following the simplest introductory tutorials.

SuperGibaLogan

xyz alright then
heres the code:

extends Area2D

var current_scatter_index = 0

@export var speed = 75
@export var movement_targets = Resource
@export var tile_map = TileMap
@export var navigation_area_2d = $NavigationAgent2D

func _ready():
 navigation_area_2d.path_desired_distance = 4.0
 navigation_area_2d.target_desired_distance = 4.0
 navigation_area_2d.target_reached.connect(on_position_reached)
 
 call_deferred("setup")
 
func _process(delta):
 move_ghost(navigation_area_2d.get_next_path_position(), delta)

func move_ghost(next_position Vector2 delta float)
var current_ghost_position = global_position
var new_velocity = (next_position - current_ghost_position).normalized()


 
func setup():
 navigation_area_2d.set_navigation_map(tile_map.get_navigation_map(0))
 NavigationServer2D.agent_set_map(navigation_area_2d.get_rid(), tile_map.get_navigation_map(0))
func scatter():
 navigation_area_2d.target_position = movement_targets.scatter_targets[current_scatter_index].position
func on_position_reached():
 if current_scatter_index < 3:
  current_scatter_index += 1
 else:
  current_scatter_index = 0

and these are the errors listed (i figured out most of them but i tried to remove the comma and colon from line 20 but it still shows the error):
Line 20:Expected closing ")" after function parameters.
Line 20:Expected ":" after function declaration.
Line 20:Expected end of statement after expression, found "Identifier" instead.

SuperGibaLogan sigh
you are using SPACES, do you not understand the difference?

gdscript uses TABS for defining pretty much everything, indentation and syntax are very much important, this isn't C# where you can skip the brackets.

SuperGibaLogan

Jesusemora i dont rlly know what tabs are though

xyz

SuperGibaLogan Don't you have the Tab key on your keyboard?

SuperGibaLogan

xyz yes

xyz

SuperGibaLogan Well press it when editing code and see what happens 🙂

SuperGibaLogan

xyz pressed it

SuperGibaLogan

xyz but what do i do next after i pressed it?

xyz

SuperGibaLogan The same thing you did after you pressed space - type a line of code.

SuperGibaLogan

xyz ok, i could try to rewrite the lines of code underneath

SuperGibaLogan

xyz so i did try to rewrite but it still gave me errors, im also thinking of searching up a pathfinding tutorial and remake the code entirely

xyz

SuperGibaLogan Post the rewritten code. You don't need more tutorials. Finish this one.

Jesusemora

SuperGibaLogan you need a using a keyboard tutorial not a godot tutorial 😮‍💨

SuperGibaLogan

xyz right here:

extends Area2D

var current_scatter_index = 0

@export var speed = 75
@export var movement_targets = Resource
@export var tile_map = TileMap
@export var navigation_area_2d = $NavigationAgent2D

func _ready():
 navigation_area_2d.path_desired_distance = 4.0
 navigation_area_2d.target_desired_distance = 4.0
 navigation_area_2d.target_reached.connect(on_position_reached)
 
 call_deferred("setup")
 
func _process(delta):
 move_ghost(navigation_area_2d.get_next_path_position(), delta)

func move_ghost(next_position Vector2 delta float):	
	var current_ghost_position = global_position
	var new_velocity = (next_position - current_ghost_position).normalized()



 
func setup():
 navigation_area_2d.set_navigation_map(tile_map.get_navigation_map(0))
 NavigationServer2D.agent_set_map(navigation_area_2d.get_rid(), tile_map.get_navigation_map(0))
func scatter():
 navigation_area_2d.target_position = movement_targets.scatter_targets[current_scatter_index].position
func on_position_reached():
 if current_scatter_index < 3:
  current_scatter_index += 1
 else:
  current_scatter_index = 0

SuperGibaLogan

Jesusemora hehe

xyz

SuperGibaLogan You need to put tabs instead of spaces for all block indentations as you did in move_ghost function. The script editor will display tabs as those subtle arrow thingies:

You can see it in the tutorial as well, that's how you know the instructor (or you) inserted a tab character there by pressing the tab key, not space. The number of tabs at the start of each line determines to which code block the line belongs. In GDScript similar to Python this indentation is used to structure the code. The structure affects the execution flow so take care not to mess it up there. One wrong tab and the code may not be working as intended.
