Android Screen Reversed

MungMoong

I finally exported Android. But the screen looks upside down. I set it to landscape. So I switched the setting to sensor_landscape so that I could rotate the screen Then, when you turn the device over, the screen flips backwards. When the first godot logo appears, it looks forward But then the game screen is completely flipped over When I touched it, I moved to the next scene, but the next scene does not show anything.

Just "landscape" should be ok. Which Version of Godot do you use currently. GLES2 or GLES3? (in case of Godot 3.1 beta)

What do we actually see on that screen. Is that a TextureFrame?

Did you try putting some controls on the screen to see if they're upside down too.

Which settings did you set on Preferences Display->Window->Stretch?

The reason that your second level does not load might be that some resources did not make it in your apk or that they were incompatible with android. A popular error is to use filenames with upper and lower case names. Windows does make no difference in filename case but all unixes will fail to load if you change the case when loading. (I.e. the file is actually named "BigOne.tres" but you try to load "bigone.tres").

I am using godot 3.0.6

I do not know what TextureFrame and putting some controls mean

I added one Button node with the text

https://github.com/godotengine/godot/issues/17083 Like the posts in this article, the touch areas are forward, but the screen flips backwards.

Stretch uses 2d mode, keep

My project's scenes and scripts all have names consisting of lowercase English characters

Looking at the GitHub issue posted, it looks like the issue is related to how Godot's OpenGL ES 3 renders on older Android devices. As mentioned in that issue, it appears that using Godot 3.1 and OpenGL ES 2 fixes the issue.

If possible, I would highly recommend making a simple Godot 3.1 project for testing. Once you have the project done I would switch the project to OpenGL ES 2 and then export it to Android. Hopefully then when you run the app on your device, the issue will no longer be present.

Barring that, I suppose you may be able to flip the entire game's main viewport through code, though from what I gathered reading the issue on GitHub, this should only be a temporary fix since newer Android devices do not exhibit the issue. Short term you could use code like this:

extends Node
func _ready():
	get_tree().root.render_target_v_flip = true;

Though I would only use a workaround like that if Godot 3.1 and OpenGL ES 2 does not work, and/or you need to keep developing and do not mind punting the issue down the road.

Hopefully this helps :smile:

Thank you very much It's still in beta 7, so I copied the project separately. I run it with OpenGL ES 2 so the screen looks right! But still the next scene does not show anything... Despite changing all nodes names to lowercase, nothing is visible
