Here's what I'm trying to make happen:

1. The object appears. (I currently have it set to appear somewhere random on-screen for testing purposes using position = Vector2(randf_range(0,get_viewport_rect().size.x),randf_range(0,get_viewport_rect().size.y)). In the game, the object will be dropped by enemies when they are defeated.)
2. The object moves away from the center and toward the closest point on a circle. This circle is centered. The circle's size can be changed at _ready().
3. Upon reaching that point, the object moves along the circumference from that point clockwise or counterclockwise.

I have tried 4 different approaches, some using parent node rotation, trigonometry, and Path2Ds, but none of them have worked and I'm out of ideas. Does anyone have any tips?

My guess is that it is a matrixed surround sound because it seems to interact with the Dolby Pro Logic II / Dolby Surround decoder on my AVR. There is very little documentation on StereoEnhance and playing with the sliders has proved interesting but not informative. Does anyone have any experience with it? Is it like QSound stereo widening?

Changing pan pullout from the default 1.0 to 0.0 creates a mono downmix, though I found that it actually removed audio information in some songs, which I found very strange.

(This is a repost because I realized I put the original post in the wrong part of the forum.)

Just for funsies, here's the code I'm using to take a screenshot. You may use it if you like! I'd like to make it so that it also takes that image it just took (image.save_png(screenshot_path)) and puts it into the computer's clipboard. That way I can just press Ctrl+V and it'll paste that screenshot

extends Node2D

@export_category("Screenshot Settings")
## If true, the screenshot will be upscaled.
## If false, the screenshot will be at its native resolution.
@export var upscale : bool = true
## Upscale by what factor?
@export var scaleFactor : int = 5

@onready var resizedWidth : int = get_viewport_rect().size.x * scaleFactor
@onready var resizedHeight : int = get_viewport_rect().size.y * scaleFactor

func _process(_delta):
	TAKE_SCREENSHOT()

func TAKE_SCREENSHOT():
	if Input.is_action_just_pressed("SCREENSHOT"):
		var date = Time.get_datetime_string_from_system().replace(".","_").replace(":","_")
		var screenshot_path = "user://"+ "screenshot_" + date + ".png"
		var image = get_viewport().get_texture().get_image()

		if upscale:
			var resizedImage = Image.new()

			resizedImage.create(resizedWidth,resizedHeight,false,Image.FORMAT_BPTC_RGBA)
			image.resize(resizedWidth,resizedHeight,Image.INTERPOLATE_NEAREST)
			resizedImage.blit_rect(image,Rect2(Vector2.ZERO,image.get_size()),Vector2.ZERO)

		image.save_png(screenshot_path)

I've tried putting DisplayServer.clipboard_set(image) or DisplayServer.clipboard_get_image() after image.save_png(screenshot_path), and looking the solution up online and I'm all out of ideas lol

Also, I'm trying to figure out what the default screenshot_path should be. I'd like to put screenshots in the user's Pictures folder or maybe the folder the game's EXE is in, but I don't really know how to do that either. As far as I can tell, user:// doesn't seem to lead anywhere.

@lemu_kymoh I'll put the exact code I'm using. (I made things less specific for the sake of the original post.)

@onready var sprPlanet : AnimatedSprite2D = $sprPlanet

...

func ANIMATION_FRAME(): #  choose a frame from sprPlanet ranging from 0 to the number of how many frames there are.
	sprPlanet.frame = randi_range(0,sprPlanet.sprite_frames.get_frame_count("planet_types") - 1)

Well as it turns out you're right! It worked. I'm not really sure what went wrong with the other tutorials...

Hi! My goal here is to pick a random frame from the frames in an AnimatedSprite2D. Right now there's only two frames, but I want to add more frames later on without having to go back into the code and change numbers around.

Right now, this is the code that works:

sprite.frame = randi_range(0,1)

This is the code I'm trying to get working:

sprite.frame = randi_range(0,sprite.sprite_frames.get_sprite_frames("default"))

(Most likely, I'll have to add a - 1 to the end of that randi_range(0,y) because it needs to reference the index of frames which starts at 0 instead of 1, not the literal amount of frames.

I've looked all around forums for an hour and tried a few different ideas, but I can't get anything that doesn't throw an error. Some people say sprite.frames_get_sprite_frames(). sprite.sprite_frames().get_sprite_frames(), and so on and none of it works. Most often it says that .frames or get_sprite_frames doesn't exist. Maybe it was in a previous version of Godot 4 or 3?

Fixed! I changed the original post to show the answer. Thank you!

@AnonyBunny New problem! It seems to work perfectly in Run Project, but not at all when exporting the game to Windows.

I submitted some bug reports to the original creator, but I don't know if they're going to see/respond to them.

@AnonyBunny
I managed to update the G3 shader text to G4, but I've hit a roadblock.

shader_type canvas_item;

uniform vec4 black : source_color;
uniform vec4 dark  : source_color;
uniform vec4 light : source_color;
uniform vec4 white : source_color;

void fragment() {
	COLOR = texture(TEXTURE,SCREEN_UV);
	float rgb_avg = (COLOR.r + COLOR.g + COLOR.b) / 3.0;
	if (rgb_avg < 0.25) {COLOR = black;}
	else if (rgb_avg < 0.5) {COLOR = dark;}
	else if (rgb_avg < 0.75) {COLOR = light;}
	else {COLOR = white;}
}

I have the "black", "dark", "light", and "white" variables all set to shades of green. The result isn't right; it's just "white". Do you know what needs fixed?

@AnonyBunny I didn't think that converting the shader code from 3 to 4 would be that simple. I'll give it a shot later and get back to you if I can manage to make it work!

@AnonyBunny Yep, that's it! I did end up getting both the MIDI and MOD Players to work by using the demo file from here, but the main download from the asset store does not work.

I like keeping file size down when I can and so I want to reduce the size music takes up. Instead of heavy compression, I thought to use sequenced music instead. Common sequenced music formats are MIDI, MOD, and MML.

I've read that "Godot can read MIDI", but after trying it out, it seems Godot doesn't even recognize .MID files.

Installing the addon and trying to enable it results in this error:

Unable to load addon script
from path: 'res://addons/midi/GMP.gd'.
This might be due to a code error in that script.
Disabling the addon at 'res://addons/midi/plugin.cfg'
to prevent further errors.

The readme that comes with Godot MIDI Player (Godot 4) does not include instructions or any relevant documentation at all on how to use the feature they created. (Possibly due to a language barrier?) However, after some digging I found this site that has very barebones instructions. However, this appears to be instructions for the Godot 3 version, so it may not work on 4 and furthermore I can't test those instructions on the 4 version because of the addon script error. I tried fixing GMP.scr so that the red error highlight disappears, but that doesn't fix the addon script error at all.

The same creator also made a Mod Player, but it has the exact same issue as the MIDI Player.

Could someone try to get this working? It could be really useful to create rhythm games, reduce music file size, or have dynamic music!

Hiii, question about color swapping shaders! I'm creating a game that resembles a Game Boy game and I would like a way to swap out different palettes in a settings menu or with a keystroke. So instead of the colors being gray, they could be shades of green or 4 separate hues.

Does anyone know how to implement a (quick) palette swap feature? There are tutorials on this, but they are for Godot 3 and don't work with 4. I'm only kinda familiar with GDScript, not at all with C#.

I think it would be possible (though not ideal) to have all the colors be separate sprites layered on top of each other, then you can use .modulate to change the colors for alllll the sprites. But I think a shader would be better.

EDIT
Fixed! Someone figured it out!

shader_type canvas_item;

uniform vec4 black : source_color;
uniform vec4 dark  : source_color;
uniform vec4 light : source_color;
uniform vec4 white : source_color;

uniform sampler2D screen_texture : hint_screen_texture;

void fragment() {
	COLOR = texture(screen_texture,SCREEN_UV);
	float rgb_avg = (COLOR.r + COLOR.g + COLOR.b) / 3.0;
	if (rgb_avg < 0.25)      {COLOR = black;}
	else if (rgb_avg < 0.50) {COLOR = dark;}
	else if (rgb_avg < 0.75) {COLOR = light;}
	else {COLOR = white;}
}

I was also told to (optionally) nest the ColorRect under a CanvasLayer node.
