I'm mostly concerned about if I'm understanding how Godot does things. I'm coming from Love2D and so messing a lot with the GUI has been a new workflow for me completely. Please disregard the absolute mess that my code is, I'm trying to get through things quickly and not necessarily cleanly. Also, I know I don't need to add 'pass' all the time, I just like the pink visual cue that my function is over, sorta like Lua lol.

I'm not sure if the way I'm doing number randomization is correct and if using duplicate() truly is the right way to remove things from the array. Is it truly deleting the node in the array? Lastly, why can't I seem to get the window size as a script-wide variable? It seems like I can only do so inside the ready function. Thanks!

edit: Code has been properly formatted, sorry!

edit2: From what I can tell this is the right way to remove objects by iterating over the array in reverse

	for a in arrows:
		a.position.y += 300 * delta

	for i in range(arrows.size() - 1, -1, -1):  #iterate safely by going backwards
		var a = arrows[i]
		if a.position.y > 540:
			health -= 10
			arrows.remove(i)
			a.queue_free()

I split up the movement code into its own for loop and then moved the deletion code into the reverse loop.

Please feel free to lmk if this isn’t the right place to be asking.

I can’t seem to find any other laptops that use a similar rubberized coating to what the thinkpads have. Do any exist out there?

I think the thinkpads are great but I don’t care for the trackpoint.

Thanks!

Not associated in any way, just taking part and wanted to let other devs know about this fun weekend game jam. Check it out if you have the time
