When turning VoiceOver ON, GCController does not send button press events for "Button A" and "Button Center".
This happens when using Siri 2nd generation remote (with dedicated arrow buttons on the circle around center button) and also when using iOS remote. I didn't test it on old Siri 1st generation with touchpad without arrow buttons.
Example:
gameController.microGamepad?.allButtons.forEach { button in
button.valueChangedHandler = { [weak self] _, _, _ in
self?.buttonHandler(gameController: gameController, button: button)
}
private func buttonHandler(gameController: GCController, button: GCControllerButtonInput) {
print("BUTTON: Pressed \(button.description) isPressed=\(button.isPressed) isTouched=\(button.isTouched)")
}
#endif
VoiceOver ON (incorrect behavior):
BUTTON: Pressed Direction Pad Left (value: 0.030, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Direction Pad Down (value: 0.079, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Direction Pad Left (value: 0.000, pressed: 0) isPressed=false isTouched=false
BUTTON: Pressed Direction Pad Down (value: 0.000, pressed: 0) isPressed=false isTouched=false
VoiceOver OFF (correct behavior):
BUTTON: Pressed Direction Pad Left (value: 0.137, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Direction Pad Up (value: 0.078, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Button A (value: 1.000, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Button Center (value: 1.000, pressed: 1) isPressed=true isTouched=true
BUTTON: Pressed Button A (value: 0.000, pressed: 0) isPressed=false isTouched=false
BUTTON: Pressed Button Center (value: 0.000, pressed: 0) isPressed=false isTouched=false
BUTTON: Pressed Direction Pad Left (value: 0.000, pressed: 0) isPressed=false isTouched=false
BUTTON: Pressed Direction Pad Up (value: 0.000, pressed: 0) isPressed=false isTouched=false
I could use for detection Direction Pad Left/Right/Up/Down and detect position between -0.7 and +0.7 and handle it as center button press, because I use that on old Siri remote where I need to distinguish center button and arrows (for switching TV channels by Up/Down and Skip forward/back by Left/Right arrows), but for new Siri remote it would be unnecessary workaround.
Does anybody know why the center/select button is not detected when VoiceOver is ON. Is there another way of detecting it using GCController?
I don't want to use SwiftUI onTapGesture for this one particular case.
Is it an unexpected bug in tvOS APIs or is there some specific reason why center button is not handled by GCController when VoiceOver is ON?
Thanks.
