Writing a game in pyvida

Please refer to the documentation in pyvida/docs

Empty Project

    app = Game(name="basic project", fullscreen=False)
    app.init()  # initialise sound and graphics
    app.run()  # start the event loop

Game with one scene

    app = Game(name="basic project", fullscreen=False)

    scene = Scene("main interface")
    app.add(scene)
    app.camera.scene(scene)  # set the camera to the scene

    app.init()  # initialise sound and graphics
    app.run()  # start the event loop

Developer

You can contribute to pyvida by cloning the github repository.

To make a scripting event, on your class add a:

def on_(self) method. self.busy += 1 # to make the event block the next event for that actor self.game._waiting = True # to make the event block all other events in the game.

pip3 install -e . --no-binary :all:
