Particles2D node issue

Hello everyone,

When i try to add "particles2d" node and make the settings like the documentation. Player turns to black.

Actually, i couldn't find how can i change the "Visibility Rect" setting to "Rect3"

The function "_on_Visibility_screen_exited" doesn't called

hi, i have downloaded the "dodge" tutorial, but something doesn't work =(

Center text in MessageLabel

Hey!

So, just one thing, when you talk about MessageLabel you should say that Align and Valign needs to be centered, otherwise someone can get a headache 😌

Attempt to call function 'start' in base 'null instance' on a null instance

This is the error I get when I press the "Start" button after running the game. I don't know where I went wrong or how. I used the video on youtube, as well as the Godot Docs step-by-step.

Mob animation not used

In Mob.gd the function

func _process(delta):
$AnimatedSprite.play()

is missing. As the guide stands the mobs have an animation but it's simply not played.
Thank you for the introductory guide :)

Clarification request

Hi there. Just went through this tutorial, and it was mostly smooth sailing, but one detail let me scratching my head for a while. I think it should be clarified that when creating the game_over signal, you need to be in the Main scene in order to connect from the player node to the main node. If you're in the Player scene, the main node isn't available. It makes sense in retrospect, but if someone is just following the steps this is a very easy mistake to make, especially since the tutorial doesn't explicitly say you're connecting to Main and not Player. I only figured it out when downloading this source and looking at Main.tscn in text. That's all, thanks!

Particle2D issue

Following the tutorial, I added the Particle2D node at the end, but when I imported the playerGrey_up1.png resource as the 'texture' (as shown in the tutorial instructions) I got a particle trail that was twice as big as the Player icon. I know the Player icon had to be scaled to 0.5, 0.5 size, but there was apparently no way to downscale the particle trail to fit the Player icon. Thus, when moving the Player icon in the game, it would leave a trail of fading supersize (2X size) Player icons - very weird.

Getting an error despite following the instructions correctly

I'm getting this error:

Invalid call. Nonexistent function 'set_deferred' in base 'CollisionShape2D' when the player is hit.

Visual scripting?

Can this game be scripted using visual scripting instead of gdscript?

Porblem with Tutorial

I did everything equal to your programm. yours working, my isnt working. The last thing what i need to implement is the music all other i finisched but my Enemies didnt spawn i cant find the issue.

Hope u can look over it.

Main:

extends Node

export (PackedScene) var Mob
var score

func _ready():
randomize()

func game_over():
$ScoreTimer.stop()
$MobTimer.stop()
$HUD.show_game_over()
#get_tree().call_group("mobs", "queue_free")

func new_game():
score = 0
$Player.start($StartPosition.position)
$StartTimer.start()
$HUD.update_score(score)
$HUD.show_message("Get Ready")

func _on_MobTimer_timeout():
$MobPath/MobSpawnLocation.offset = randi()
var mob = Mob.instance()
add_child(mob)
var direction = $MobPath/MobSpawnLocation.rotation + PI / 2
mob.position = $MobPath/MobSpawnLocation.position
direction += rand_range(-PI / 4, PI / 4)
mob.rotation = direction
mob.linear_velocity = Vector2(rand_range(mob.min_speed, mob.max_speed), 0)
mob.linear_velocity = mob.linear_velocity.rotated(direction)

func _on_StartTimer_timeout():
$MobTimer.start()
$ScoreTimer.start()

func _on_ScoreTimer_timeout():
score += 1
$HUD.update_score(score)

position.y = clamp(position.y, 0, screen_size.y)

if velocity.x != 0:
$AnimatedSprite.animation = "Walk"
$AnimatedSprite.flip_v = false
# See the note below about boolean assignment
$AnimatedSprite.flip_h = velocity.x < 0

StartTimer firing after game over

If the player suffers an early death then StartTimer can fire after the game over.

This kicks off MobTimer and ScoreTimer which continue to fire while the menu is displayed.

This can exacerbate the problem because MobTimer will ensure that there are enemies on the screen increasing the likely-hood of an early death next time.

`Parser Error: Identifiers not found: screensize`

extends Area2D

export (int) var speed #how fast the player will move

func _ready():
		screensize = get_viewport_rect().size

func _process(delta):
	var velocity = vector2() #player's movement vector
	if Input.action_pressed("ui_right"):
		velocity.x += 1
	if Input.actio_pressed("ui_left"):
		velocity.x -= 1
	if Input.is_action_pressed("ui_down"):
        velocity.y += 1
	if Input.is_action_pressed("ui_up"):
		velocity.y -= 1
	if velocity.length() > 0:
		velocity = velocity.normalized() * speed
		$AnimatedSprite.play()
	else:
		$AnimatedSprite.stop()
		
	position += velocity * delta
	position.x = clamp(position.x, 0, screensize.x)
	position.y = clamp(position.y, 0, screensize.y)

This is the code from the tutorial. When I tried to run it. It throws error:
Parser Error: Identifiers not found: screensize

Please help

Deathsound is Dead

As the title says I can't get the Deathsound to play. Music plays without issue but whenever 'game over' occurs I get the error: Node not found: DeathSound.

The .wav file is loaded in the streaming box. I listened to and it plays fine in windows. Without the deathsound file the game plays fine.

Anyone else have this issue?

Minor feedback trying to follow along

• The line $Collision.disabled = false at
  https://github.com/kidscancode/Godot3_dodge/blob/master/Player.gd#L16 this line is not mentioned in the guide (https://godot.readthedocs.io/en/latest/learning/step_by_step/your_first_game.html)

• The line $Collision.disabled = true at
  https://github.com/kidscancode/Godot3_dodge/blob/master/Player.gd#L47 is not mentioned, instead call_deferred("set_monitoring", false) is suggested with a rationale "you can defer the change, which will tell the game engine to wait until it’s safe to set monitoring to false", is this true?

• The screenshot https://godot.readthedocs.io/en/latest/_images/player_scene_nodes.png has a node named "Collision". The guide doesn't mention naming it like this.
