Issue with Velocity and Delta - L2:P1NPCChrisI had an issue with this practice in that the second test was failing: **"Bullet Moves Based on Velocity And Delta"**
I had everything correct, but was using a velocity of Vector2(480, -480). This second test was returning as a fail, but after I checked here I tried again with Vector2(500, -500) and it passed. I'm not sure if that is intended, but if so it would help to make the text more clear about *why* the failure is recurring. My assumption was that it was something to do with velocity * delta due to the message, but that was not the case. Thanks for the course!115Feb. 05, 2024
L3.P1 questionmiiaIn the practice, L3.P1, I solved it on my first try by changing `velocity := Vector2(0,0)` to `Vector2(1,1)`.
....But I don't know why this worked, haha. The bullet did not actually move. I'm not entirely sure what this module was asking me to do, either. We don't want `direction = Vector2(0, 0)`, and I see why this solution changed that value. But I just don't feel confident that was the intended solution. Maybe it was?
Additionally, I think I was confused because one of the PASSED requirements was "Ship Moves With Pressed Direction Keys" and we have not implemented that yet.34Feb. 04, 2024

I don't know if I'm missing something or it's a bugAlcedoHi, I don't know if I'm miss reading the task or I have found a bug for the practice L2.P1.
If I put a number different from `-500` for the y value of the var `velocity` (e.g. `-450`), when I run the practice it tells me that I didn't pass the second condition (Bullet Moves Based On Velocity And Delta).12Feb. 04, 2024
Typo in sentence.tehdinozorzYes, the ship moved down! You might have learned in math class esthat positive y coordinates are up. But in 2D games, the y-axis usually points down.11Feb. 04, 2024
Question - PropertiesspxcyOn Experimenting with moving the ship, we learn that Sprite2D has the position property. How do we verify this? I am looking at the documentation and don't see "position" under the listed properties. I see centered, flip_h, flip_v, etc. 10Sep. 14, 2024

L3.P1 Test setup failedJHawkeWhen I click on run for this lesson the text on right is saying test setup failed and the sprite on the right is not moving at all while my code one on the left is. But as the test is not running my code is not being verified and then lesson is stuck. 10Aug. 18, 2024
I'm dumbniyisPlease mention somewhere in the instructions that when you hit "Run" the left side of the screen is YOUR CODE, and the right side is DEMO, I'm so dumb, that took me forever to figure out.

Godot crashes when I enable "GDQuest Practices"VovaI encountered the same issue with "M02.getting_to_know_godot". Now I have it with "M04.to_space_and_beyond_workbook". I understand this plugin solution is innovative, but I'd rather read stuff on a web page that doesn't crash.

Is there a way to reset the progress of the online modules?leafHey guys, I'm back at it. Starting over with M4 and was curious if there was a way to completely reset my progress with the online modules? I.E. questions and answers, lesson practices, etc. (I re-downloaded a fresh copy of the workbook projects)50Jul. 21, 2024
Lesson Numbering Oversightgraceful-clamHi Godot Team :)
In the spirit of teamwork - I noticed a formatting error in the module numberings.
M2, M4, M5, M6, M**0**7, M**0**8.
In the local project panel, when I went to sort the files naming conventions - M07 & M08 end up on top since the "0" is present.
This may be intentional, and I have not gotten far enough in the course yet. However if not, I would like to put forward the suggestion of adding a 0 in M2, M4, M5, M6 to future proof any additions in the double digits for the content, and ease of sorting for other students.
Respectfully,10Jul. 20, 2024
Why does delta have a type of float?profuse-otterMy intuition tells me that an int (as ms or ns since the last frame) would be more precise. Is it just a convenience?10Jul. 08, 2024

Am I supposed to enable/disable the plugin?perlanceHello!
Before the practice my code differs from what it's supposed to be after the practice, this results in "Run current scene"(F6) giving a fail, am I supposed to disable the plugin and only enable it once I reach the practice part?20Jun. 16, 2024
Question about incrementationHazlarI don't understand the difference between:
case 1:
```gdscript
var velocity := Vector2(300, -300)
func _process(delta: float) -> void:
position += velocity * delta
rotation = velocity.angle()
```
and (+= velocity)
case 2:
```gdscript
func _process(delta: float) -> void:
position = velocity * delta
rotation = velocity.angle()
```
In case 1, if position = 0 :
Frame 1: position = 300,-300
Frame 2: position = 0 ,0? or 300 ,-300?
Because in both cases the ship moves in the same direction. But in this case the exercise is considered unsuccessful.
Thanks !! 10Jun. 08, 2024
DeltaMainzelHi there just wondering how many frames delta actually allows to use or is it fixed to 60 fps? (sry for bad english)10Jun. 04, 2024
Practice is strictKalmaroSo I kept failing this and wasn't sure why, since I copy pasted code I made for the lesson and modified this. Then I realized that I was multiplying the velocity by delta... and then by another number because I was experimenting with speed.
I still got the correct direction, but the practice said I wasn't using delta, when I was.10Jun. 01, 2024
Why doesn't my code pass every check?choodle```gdscript
extends Sprite2D
# Change the bullet's velocity to move towards the top right.
var velocity := Vector2(500, -500)
# Complete the process function to make the bullet move based on the velocity
# vector. Also, rotate the bullet to match the velocity vector's angle.
func _process(delta: float) -> void:
rotation = velocity.angle()
position = velocity * delta

Put the added and removed line indicators in the code gutterWalruswareThe code view with the +/- indicators for changed code is really helpful, but with the icons being at the line start it pushes all the following code across out of allignment. This is going to become very confusing to follow eespecially as tabs become more important and being able to see how code is nested will be vital for understanding the code.
Here you can see that the rotation line should allign with the position line above it but instead it is poushed over by the + which makes it look indented.
`var velocity := Vector2(480, -480)`
`func _process(delta: float) -> void:`
`position += velocity * delta`
`+ rotation = velocity.angle()`
Please consider putting the line added and line removed icons in the gutter so that they don't misalign the lines of true code. 10May. 13, 2024
Running Scene doesn't workJakkuHey there, new to GDQuest! Trying to troubleshoot an issue w/ running the scene: every time I attempt to run it, I only get a blank grey screen and end up having to end process (due to it not loading in time).
This may be a version issue: I also have version 4.2.2, and running scenes in that version works perfectly fine. I get the godot icon and everything, but not when running scenes in 4.2.1 (or at least the version w/ the workbooks and solutions projects). Any suggestions?20May. 12, 2024
L2.P1complex-hornetThe solution bullet that plays every time the code is run was initially confusing. This behavior isn't explained so when I first started changing the velocity vector before implementing the _process code I couldn't figure out why the changes weren't taking effect.10May. 09, 2024

I am unsure if this is getting in the way of my progress. The plugin does show and it does give me the instructions so no issues so far, but the erros can be a bit daunting, especially because before the plugin wouldn't work, I unzipped the project once more and that helped, but still facing those errors described above. 10May. 08, 2024

_process functiondatiswousWhat I understood is that the _process function is a special function inside Godot.
So I don't understand why you devine it. It would be logical to call it, because it already excists, but defining an already excisting function makes no sence to me.
Is this documented somewhere?10Mar. 06, 2024
Some small errors on this pageCornflakes- When you refer to a drop-down menu, I think that really is a context menu.
- There is a word missing here (Did you miss the word 'takes'?) -> "The engine automatically opens the newly created script file and you to the Script editor."
- There is another word missing in the info box "Why is there a colon [...]" (Did you mean 'the' variable type?) -> "Similarly, we can explicitly tell the computer what variable type is when we define it."10Mar. 06, 2024
When to define a functionStonemonkeyWe use `func *process():`* but I thought `_process()` is inherited from Node.
TLDR: If _process(): already exists(is inherited from Node), why do we define it?
I thought we use the *`func fuction_name():*` to define fuctions that don't exist yet, and after that we can call on them without using func.
The `move_forward()` fuction in the Learn GDScript from Zero app, which was a function provided and I assume defined "behind the scenes". We used that inside of a function that we defined.
Or does every individual script need the functions to be defined first per usage in the script.50Mar. 05, 2024
Documentation helpTucanBigAs stated inside this lesson , angle and position are member variables. Where can I find all the member variables a node has?

Rotating clockwise is positive ~ crazyMonarchcontrary to how the normal radians (pi/2) which is 90degree is anti-clock rotation of circle. so positive (pi/2) is actually rotating 90 degree in clockwise but in real math's its counterclockwise. the 2d space in this engine seems to be complete opposite. Like how positive y is downward, seems a little different.10Feb. 25, 2024

Issues recreating lesson code NinjoshHello.
I tried to use the code:
extends Sprite 2D
var velocity = Vector2(480, -480)
func _process(delta: float) -> void:
position += velocity * delta
rotation = velocity.angle()
but I am unable to see the ship. It seems that when velocity = Vector2(500, 0) I am able to see the ship and the ship moves and faces right. This is correct for Vector2(500, -100) as well but the ship is not in the middle anymore moving right but starts higher up. Vector2(500, -200) has the ship almost off the screen. I am a bit confused why this is happening?
Thanks for the lessons. 20Feb. 09, 2024

Complete CodeAdamsapHi there this is not a question but is a heads up. in your drop down for complete code for ship.gd. your velocity is incorrect. your line is:
var velocity := Vector2(500, 0)
shouldn't it be:
var velocity := Vector2(500, -500) if you want it to move to the top right corner? 10Feb. 03, 2024
