Weird graphic bug

BizarreOfNature

Hello!

It's me again with probably another newbie problem.

I want to make a scrolling background. And it works. However, only at certain speed

extends Node2D

export var Speed = 150

func Scroll(Delta):
	if $Sprite_Background1.get_position().y < get_viewport_rect().size.y:
		$Sprite_Background1.set_position(Vector2(0, $Sprite_Background1.get_position().y + Speed * Delta))
		$Sprite_Background2.set_position(Vector2(0, $Sprite_Background2.get_position().y + Speed * Delta))
	else:
		$Sprite_Background1.set_position(Vector2(0, 0))
		$Sprite_Background2.set_position(Vector2(0, -800))

For example at speed 150 there is a line where you cant see background textures. At 250 or 50 there is none. I cant see an error in my code. I would be glad for any help.

Best regards Bizarre

Can you explain the purpose of your code a little bit? What are Sprite_Background1 and Sprite_Background2? How Scroll is called

You can post code by adding "~~~" (without quotes) on a line by itself (right above and right below the code). This will have it displayed properly in the forum. I fixed your post for you.

I do n’t know why you want to keep the two backgrounds moving at the same speed, but I still tried it and everything is fine this is code

extends Node2D

export var Speed = 150

func _ready():
	pass # Replace with function body.

func _process(delta):
	if $Sprite1.get_position().y < get_viewport_rect().size.y:
		$Sprite1.set_position(Vector2(0, $Sprite1.get_position().y + Speed * delta))
		$Sprite2.set_position(Vector2(0, $Sprite2.get_position().y + Speed * delta))
	else:
		$Sprite1.set_position(Vector2(0, 0))
		$Sprite2.set_position(Vector2(0, -800))

Thanks for the help guys!

Sprites are simple TextureRects. They load a .tga file and are totally default, except the start position.

Basically I let 2 TextureRects move down and when they reach the windowborder i set them back. Btw. if i change -800 to -799 the bug is gone. But I cant do this, its bad coding.

This is how its called:

func _process(Delta):
	Process_Main(Delta)

func Process_Main(Delta):
	Background.Scroll(Delta)

I was wondering why it never worked haha. Thanks!

Try only using integers. So on the movement code:

$Sprite_Background1.set_position(Vector2(0, round($Sprite_Background1.get_position().y + Speed * Delta)))

You could also indent your code once before copying, then pasting it will result in it automatically getting formatted as code. And if you select some text in your post while writing it and use the code formatting option from the top bar it adds a level of indentation

like
this

but only if it's multiple lines, otherwise it adds formatting for inline code via `` instead.

For example at speed 150 there is a line where you cant see background textures This line is between the two pictures? or sometimes appears?

I tested the code, I feel there is no problem
