Hello. I've followed the Your First Game (https://docs.godotengine.org/en/stable/getting_started/step_by_step/your_first_game.html) tutorial to a T and for the most part, it works however there is one weird bug I've noticed that I can't quite figure out.

The Mob should be created offscreen following the PathFollow2D node and for the top, left and right parts of the path, it works perfectly. For the bottom however, mobs are created about midway up the screen (almost like they appear out of thin-air). The player can hang out in the bottom and avoid most of the mobs unless they spawn from the top.

I've been trying to figure out why this happens but I can't. I've tried resizing and redrawing the Path2D but the same thing happens. Any idea on what might be happening here or a way I can troubleshoot this?

Can I see your Main.gd code?

Sure thing! Here it is:

extends Node

export (PackedScene) var Mob
var score

func _ready():
	randomize()

# Declare member variables here. Examples:
# var a = 2
# var b = "text"

func game_over():
	$ScoreTimer.stop()
	$MobTimer.stop()
	$HUD.show_game_over()

func new_game():
	score = 0
	$Player.start($StartPosition.position)
	$StartTimer.start()
	$HUD.update_score(score)
	$HUD.show_message("Get Ready")

func _on_MobTimer_timeout():
	# Choose a random location on Path2D.
	$MobPath/MobSpawnLocation.offset = randi()
	# Create a Mob instance and add it to the scene.
	var mob = Mob.instance()
	add_child(mob)
	# Set the mob's direction perpendicular to the path direction.
	var direction = $MobPath/MobSpawnLocation.rotation + PI / 2
	# Set the mob's position to a random location.
	mob.position = $MobPath/MobSpawnLocation.position
	# Add some randomness to the direction.
	direction += rand_range(-PI / 4, PI / 4)
	mob.rotation = direction
	# Set the velocity (speed & direction).
	mob.linear_velocity = Vector2(rand_range(mob.min_speed, mob.max_speed), 0).rotated(direction)
	#mob.linear_velocity = mob.linear_velocity.rotated(direction)
	$HUD.connect("start_game", mob, "_on_start_game")

func _on_ScoreTimer_timeout():
	score += 1
	$HUD.update_score(score)

func _on_StartTimer_timeout():
	$MobTimer.start()
	$ScoreTimer.start()

I've compared the code from https://github.com/godotengine/godot-demo-projects/tree/master/2d/dodge_the_creeps to my code and apart from the comments and the addition of music and sounds, it all seems the same.

mr_moon

did you check the window size under project settings?

weddi_eddy

Hey! I figured it out! So, the MobPath Path2d was scaled and not set to 1,1. The scale caused it to seem like it was the full window size but it wasn't. Once I changed the y scale back to 1, it showed me a path that looked oddly similar to where the mobs were spawning. I resized the Path2d and the 1,1 scale remained.

I ran the game and it worked like a charm! Thank you for your help! Your questions may not have lead me to figure this out.
