Step 1 - Install and Open a Window

Our first step is to make sure everything is installed, and that we can at least get a window open.

Installation

• Make sure Python is installed. Download Python here if you don’t already have it.

• Make sure the Arcade library is installed.

  • You should first setup a virtual environment (venv) and activate it.

  • Install Arcade with pip install arcade.

  • Here are the longer, official Installation.

Open a Window

The example below opens up a blank window. Set up a project and get the code below working.

Note

This is a fixed-size window. It is possible to have a Resizable Window or a Full Screen Example, but there are more interesting things we can do first. Therefore we’ll stick with a fixed-size window for this tutorial.

"""
Platformer Game

python -m arcade.examples.platform_tutorial.01_open_window
"""
import arcade

# Constants
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600
SCREEN_TITLE = "Platformer"


class MyGame(arcade.Window):
    """
    Main application class.
    """

    def __init__(self):

        # Call the parent class to set up the window
        super().__init__(SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_TITLE)

        self.background_color = arcade.csscolor.CORNFLOWER_BLUE

    def setup(self):
        """Set up the game here. Call this function to restart the game."""
        pass

    def on_draw(self):
        """Render the screen."""

        # The clear method should always be called at the start of on_draw.
        # It clears the whole screen to whatever the background color is
        # set to. This ensures that you have a clean slate for drawing each
        # frame of the game.
        self.clear()

        # Code to draw other things will go here


def main():
    """Main function"""
    window = MyGame()
    window.setup()
    arcade.run()


if __name__ == "__main__":
    main()

You should end up with a window like this:

Once you get the code working, try figuring out how to adjust the code so you can:

• Change the screen size(or even make the Window resizable or fullscreen)

• Change the title

• Change the background color

  • See the documentation for arcade.color package

  • See the documentation for arcade.csscolor package

• Look through the documentation for the arcade.Window class to get an idea of everything it can do.
