I just added a TouchScreenButton to an existing project and tested it with an Android export from Godot 4.3-dev1. It worked correctly.

To test it, I added a child Label to it and attached this script, which increments a displayed count on each button press:

extends TouchScreenButton

func _ready() -> void:
	$Label.text = "0"
	pressed.connect(func(): $Label.text = str(int($Label.text) + 1))

I generally use normal buttons, which for Android require enabling the project setting input_devices/pointing/emulate_mouse_from_touch, but that's not needed for a TouchScreenButton.

    belgian_street_lamp Can you test it in godot 4.2.1?

    I've deleted the test code. But you can create a minimal project to test it in 4.3-dev1. I doubt if there's been a change in that area.

    By "minimal project", I mean a project that contains nothing but the button, label and script.

    If it fails in both 4.2.1 and 4.3-dev1, upload the minimal project.

      I downloaded the .zip, imported it into Godot 4.3-dev1, and exported it to Android using one-click install. The TouchScreenButton works.

      The only change I made was to disable "Use Gradle Build" in the Project / Export settings. I had to do that so that I can use the standard export templates.

      So maybe it is because of gradle? Idk what to do really i have like 100 of theese touchscreenbuttons in my game.

      If it's a bug, why does the button work for me?

      Did you try disabling "Use Gradle Build"?

      Try searching the github issues. I found several by searching for "TouchScreenButton".

        DaveTheCoder Maybe it only doesnt work when you use gradle. From my understanding i need to use gradle because of my plugins or something.

        edit: it also doesn't work without grade. I have know idea what im doing wrong T-T

          Tested two different projects on 2 different versions of godot on 2 different emulators with different settings, nothing works. Slowly loosing my mind 🙂

          I installed test2.apk on my Android phone.

          Both buttons work. If I touch the left button, "touchscreen button pressed" is displayed. If I touch the right button, "normal button pressed" is displayed.
