We have now completed all the functionality for our game. Below are some remaining steps to add a bit more "juice" to improve the game experience. Feel free to expand the gameplay with your own ide...

It appears that the node types are now AudioStreamPlayer2D instead of just AudioStreamPlayer. I had to correct that in the code to get the music to play. Very awesome to complete this tutorial.

[Calinou]

Both AudioStreamPlayer and AudioStreamPlayer2D still exist in Godot 4. AudioStreamPlayer should be used for music playback, as it's non-positional, while AudioStreamPlayer2D should be used for positional audio (i.e. most sound effects).

[ninlar]

Whoops I see it now. Not sure how I missed that node :(

how can add touchscreen input to this if i export this game to android?

[timhutton]

One way is to move the player towards where the user is touching. In player.gd, add:

var touch_is_down = false
var touch_target

func _input(event):
	if event is InputEventScreenTouch:
		if event.pressed:
			touch_is_down = true
			touch_target = event.position
		elif event.released:
			touch_is_down = false
	elif event is InputEventScreenDrag:
		touch_target = event.position

and then in _process() you can add:

	if touch_is_down and position.distance_to(touch_target) > 5:
		velocity = touch_target - position

I made a small addition that may be suitable for here, which is hiding the player when the app runs and showing them when the game starts. I thought seeing the player on the title screen was odd.

Added

func new_game():
    ...
	$Player.show()

func _ready():
	$Player.hide()

[ZakariGames]

This was already part of the tutorial actually! :D

Right before adding the collisions in the "Coding the Player" section is when we add the hide() function to the player's _ready() function.

"When you're sure the movement is working correctly, add this line to _ready(), so the player will be hidden when the game starts:"

"hide()"

And then at the very end of the "Coding the Player" section, the show() function is added to the player's start() function:

"The last piece is to add a function we can call to reset the player when starting a new game."

func start(pos):
position = pos
show()
$CollisionShape2D.disabled = false

For the sound effects section mine was missing the Loop checkbox. However based on this forum post I was able to do this by connecting the AudioStreamPlayer's finished() node to main and telling it to start playing the music when the audio finished signal fired like so

func _on_music_finished() -> void:
	$Music.play()

[Calinou]

Note that a script-based approach to audio looping may not perform gapless playback correctly, so you might hear a small amount of silence between each loop.

[islam3zzat]

have u tried enabling the looping and reimporting the resource?
This has worked for me

[associateone]

You have to make it unique as the tutorial says in order to enable the Loop checkbox.

[associateone]

All audio is automatically imported with the Loop setting disabled. If you want the music to loop seamlessly, click on the Stream file arrow, select Make Unique, then click on the Stream file and check the Loop box.

Pull request opened:

• Link to Exporting projects in Finishing up page of Your first 2D game godot-docs#9976

[SteeveBlanc]

to export the game and show it proudly :
Project/Export
Add...
Windows runnable / Mac
it says some config files are missing
add them with the option on the right, Godot downloads automatically from best source
ok, re-open Project/Export
this time you are allowed to press Export project
create a subfolder and choose it
Go.
4 files are generated (on Windows), 3 are necessary but the console.exe seems optional
you can zip the folder with 3 files and send it

While pressing the button I get this error:

E 0:00:01:0767 event_get_action_status: The InputMap action "start_game" doesn't exist. Did you mean "ui_text_caret_document_start"?
<C++ Error> Condition "!E" is true. Returning: false
<C++ Source> core/input/input_map.cpp:262 @ event_get_action_status()

[thomzd]

EDIT: even though I have the start_game function in my script:

signal start_game
#...
func _on_start_button_pressed() -> void:
$StartButton.hide()
start_game.emit()

[jsonjunkie]

seems like you might need to add the start_game Input Map. go to Project > Project Settings > Input Map and then add new action named start_game

[jessodum]

I don't know if this is something new in 4.3 (I'm completely new to Godot as of this week), but I think I found easier instructions to enable the music looping.

Instead of this:

If you want the music to loop seamlessly, click on the Stream file arrow, select Make Unique, then click on the Stream file and check the Loop box.

... do this instead:

In the Inspector for the Music node, expand the Parameters under AudioStreamPlayer and make sure both the "Looping" and "On" checkboxes are checked.

[ElectricZax]

This is what I used. I didn't even find the first one and I thought it was me. But your comment made me look for it again and I found it.

Thank you.

[ElectricZax]

I don't know what is the proper protocol here... but can we have a separate page or section or maybe a Discord group where we can discuss various ways we improve and build on the game and how to do new things?

For example I added a button with function "boost", so when I press it the speed of my creep will double.
if Input.is_action_pressed("move_right"):
velocity.x += 1*boost

But I can't make an "if" condition to increase the speed when score > 30 for example (because I don't know how to setup the if rule to check the score).

[ElectricZax]

I could not make the "game_start" button to work. (I skipped part of the instructions, because I thought it was related to the controller support).
In the end I added to the main script the below code and it worked.

func _process(delta):
if Input.is_action_pressed("start_game"):
new_game()

[pikaphew9000]

My game is not working.
The MObs are off scale and rotation I cant fix it
Also instead of running the main scene as its supposed to it runs the player scene when i press the run button

[Eilliw11]

I'm seeing a lot of little snips and pieces of the finished script we're supposed to write, but where these pieces go is pretty vague, and I'm almost certain not complete. It looks like there is an assumption that once you've got something figured out in one place, you'll automatically know what goes in somewhere else without any instruction. That's not really the case. Does the completed project exist somewhere to compare what I've done to a known good example? Then I can see if something is in the wrong place or if anything is missing. I can go through line by line, and see it's doing everything I told it to do. It just isn't doing everything the example is doing. Without a known good script to compare it to, I can't see the mistake neither I nor the debugger caught.

[Eilliw11]

Oh! Found it. Godot-demo-projects/2d/dodge_the_creeps. Found all three scripts right there. Not even a minute after asking, I found it. But if anyone is just a LITTLE off, there is a known good example. Literally one letter off for mine.
