Hardware keyboard input when scene is running

[KiloPasztetowej]

Hey. I searched and searched but I couldn’t find definitive answer to the question, whether querying hardware keyboard state is possible in Pythonista when using scene. I know it can be done with UIKit but this doesn’t fit my needs. I love my iPad and I’d like to use it for some quick prototypes for my games but I just prefer keyboard input over touch.
Any support would be welcome (events or just queries for keys)!

@KiloPasztetowej, I assume that by UIKit support you are referring to the ui.View.get_key_commands and key_command(sender) methods.

Since scene always runs in a
UI view, you can create a custom ui.View that utilizes the above methods, and then use that as your scene’s view.

Something like this – end with a two-finger swipe down:

import ui
import scene


class MyKbHandler(ui.View):
    
    def __init__(self, my_scene, **kwargs):
        super().__init__(**kwargs)
        sceneview = scene.SceneView(
            frame=self.bounds, flex='WH',
        )
        sceneview.scene = self.scene = my_scene
        self.add_subview(sceneview)
    
    def get_key_commands(self):
        return [
            # Custom commands
            { 'input': 'A' }
        ]
        
    def key_command(self, sender):
        # Process commands, e.g.:
        if sender['input'] == 'A':
            self.scene.accelerate()


class MyScene(scene.Scene):
    
    def setup(self):
        self.ship = scene.SpriteNode('spc:PlayerShip1Orange')
        self.ship.position = self.size / 2
        self.add_child(self.ship)
        
    def accelerate(self):
        x, y = self.ship.position
        self.ship.position = (x, y + 20)
        

root = MyKbHandler(my_scene=MyScene())

root.present('fullscreen', hide_title_bar=True)

Great! Works like a charm and that’s exactly what I need. Thank you very much 🙂
