Hello friends from the Godot forum, I am a game development enthusiast from China who has just started using Godot. Currently, I am working on a remake of a game called DNF. When I migrated the project from version 4.4 to 4.6, the following issues arose, and I am seeking your assistance. This is my first time seeking help on the forum, so please forgive me if I have not followed the forum guidelines.

The issue that emerged after upgrading the replication project from Godot 4.4 to version 4.6 is demonstrated in the video below. The window on the left shows a 4.4 version where the character moves to the edge of the map without any jitter. The window on the right shows a 4.6 version where the character moves to the far right of the map and wanders back and forth, causing the map to jitter. What is this issue? Can someone help me understand it?

I have tried both 2D transform-adsorbed pixels and 2D vertex-adsorbed pixels, but neither solved the problem. Is there still something I haven’t chosen properly?

Currently, it has been tested that as long as the size of the map’s x-axis does not exceed the range of 1500px, the character will not experience jittering when moving to the edge. This is incredible

Welcome buddy, hmm… that’s interesting… I don’t think is Godot changed the input methods in the last update.

I need to know your character’s input handler, then we’ll move on to visualization, specifically parallax processing.

Perhaps your background and character share some common input handling. It’s hard to say anything right now until I see the code.

extends CharacterBody2D

func _process(delta: float) -> void:
	var fx = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
	velocity = fx * 250.0
	move_and_slide()

I have rewritten a project, which only includes the code for character movement, with no code control for other nodes. However, the problem still persists.

What are your Camera2D limits set to?

Try making them slightly smaller, see if the problem goes away. Then try removing them. See if the problem goes away. The point of this is to try and find the problem - these are not recommended solutions.

Currently, after testing, as long as the x-axis size of the map does not exceed a range of 1500px, there will be no jitter when characters move to the edge. This is incredible, but if all maps are limited to an x-axis size of 1500px, it will restrict the playability of the game.

  • I forgot to ask you to check what happens if you increase it. You should test that as well.
  • A 500 pixel difference is huge. What was the resolution of the game when 1500 pixels worked?
  • Is smoothing enabled or disabled? Does changing it help, hurt, or do nothing?
  • Does changing the pixel smoothing amount have any effect?
  • What happened when you removed this limits entirely?
  • Did changing the vertical limits have no effect?

Thank you for providing the step-by-step inspection method. Currently, this issue has been submitted to the official and identified as a problem with camera related code after version 4.5. It may be fixed in the future.
