If you comment out line 20 in the enemies (queue_free()) and replace it with queue_free do the enemies appear? It could be that the enemies are spawning off screen and so they are instantly deleted before they have a chance to become visible. If so, you may need to adjust the code some, but I'd check to see if this is what is causing the issue first before trying to implement a solution, as it could be something else.

Looking at the code, is this the your first game project from the Godot documentation? If so, something to check might be how the Path2D was constructed, as it needs to be in a certain way (clockwise I think) for the enemies to move inwards when they spawn rather than outwards.

Yes, this is the "your first game project" tutorial. After reading your reply, I deleted the last 3 points on the Path2D and did it again, though both times I followed the clockwise direction as in the tutorial. Ran the game, and I still don't see enemies.

When I took out the () at the end of queue_free it gave me an error and the game didn't run at all.

So I'm still confused.

If this is Dodge the Creeps, there should be another line at the end of func _on_MobTimer_timeout():

mob.linear_velocity = mob.linear_velocity.rotated(direction)

That affects the direction that the creeps travel, but it doesn't explain why they never appear on the screen.

I don't know how I missed that line in the tutorial.

I'm guessing it won't make a difference until I can get the "creeps" to actually spawn on screen.

Nothing like being unable to get successful results from the first game tutorial to make me feel like I am in way over my head trying to learn a program. This makes me sad. I really hate redoing stuff, but I guess I should redo the tutorial again and again until it works. But not knowing what I did wrong means I have to hope that whatever I did the first time was a fluke mistake that I won't make this time.

I appreciate you trying to help.

Try putting print statements in all the timeout functions and see if they are actually being called.

print("mob should spawn now")

Or something like that.

Also, did you draw a path and is the path on the screen?

Before doing that, you could compare your scripts with the tutorial's, and make sure there are no differences. Also the scene tree structure, node names, etc. Just one wrong character could mess things up.

Using cybereality's suggestion to use print statements for debugging is a good idea too.

cybereality

No need to redo the tutorial. Try to figure it out, that's how you learn.

Thanks. Where does that go? Do I tell it to print on the same line as each timeout function, or the next line down? How would I know if they are being called or not? This is my first time doing this sort of thing.

As far as trying to figure it out rather than redoing, I already did. I hate bugging people for help, so I only post here when I have tried numerous times to figure out what went wrong, and can't think of what else to do. I found few mistakes and fixed those before I posted, but none made the game fully work. I normally have no problem following tutorials, but it seems that my dyslexia and / or other issues are really not suited well for programming. But hopefully if I stick with it, I can work past those issues.

Okay. For example you can do this:

func _on_StartTimer_timeout():
    $MobTimer.start()
    $ScoreTimer.start()
    print("starting timers")

And that will show a message in the output window of the editor (on the bottom) or on the command line.

Thanks. I did it, and no message showed up in the output window. So does that mean it's not they are not being called?

cybereality

Yes, that is the first step you do when looking for a problem. If you don't see the text, that means the timers are not working. It could mean there are incorrect settings on the timer (check that they exist in the scene tree, that they are named correctly, and then look in the inspector on the left and see if it looks okay). If everything looks right, it probably means the scripts are not attached to the right objects. You can put similar print statements in _ready() for all the scripts and see if they are being called. Check that the Nodes are in the scene and that they have the correct scripts attached.
