Make a game with kivy

If you are interested in developing games using Python, kivy is a great framework to consider. Kivy is an open-source Python library for developing multitouch applications, and it includes tools for creating games with rich graphics and responsive user interfaces. In this article, we will explore how to make a simple game using kivy.

Getting started with kivy

Before we start building our game, make sure you have kivy installed. You can install kivy using pip:

        pip install kivy
      

Creating the game window

Let’s start by creating a simple game window using kivy. We will create a basic game with a colored rectangle that the user can control.

        from kivy.app import App
        from kivy.uix.widget import Widget
        from kivy.uix.label import Label
        from kivy.uix.floatlayout import FloatLayout

        class GameWindow(App):
            def build(self):
                layout = FloatLayout()
                label = Label(text='Welcome to the game!', size_hint=(.5, .5))
                layout.add_widget(label)
                return layout

        if __name__ == '__main__':
            GameWindow().run()
      

Adding interactivity

Now, let’s make the game interactive by allowing the user to control the position of the rectangle. We will use kivy properties to define the position and size of the rectangle, and update it based on user input.

        from kivy.uix.button import Button

        class GameWindow(App):
            def build(self):
                layout = FloatLayout()
                label = Label(text='Welcome to the game!', size_hint=(.5, .5))
                button = Button(text='Move rectangle', size_hint=(.2, .1), pos_hint={'x': .4, 'y': .4})
                layout.add_widget(label)
                layout.add_widget(button)
                return layout

            def on_button_press(self):
                # Update the position of the rectangle
                pass

        if __name__ == '__main__':
            GameWindow().run()
      

Final thoughts

With kivy, you can create complex games with rich graphics and interactive elements. This article only scratches the surface of what is possible with kivy, but it should give you a good starting point to explore game development with Python.
