Pyglet进入类

Question

鉴于到目前为止我一直使用Pygame，我想开始使用Pyglet，了解它的工作原理。

import pyglet, os

class runGame():
    widthDisplay = 1024
    heightDiplay = 576
    title = "Pokémon Life and Death: Esploratori del proprio Destino"

    wra = pyglet.image.load("wra.png")
    wrb = pyglet.image.load("wrb.png")

    def __init__(self):
        platform = pyglet.window.get_platform()
        display = platform.get_default_display()
        screen = display.get_default_screen()
        self.widthScreen = screen.width
        self.heightScreen = screen.height
        self.xDisplay = int(self.widthScreen / 2 - self.widthDisplay / 2)
        self.yDisplay = int(self.heightScreen / 2 - self.heightDiplay / 2)
        self.Display = pyglet.window.Window(width=self.widthDisplay, height=self.heightDiplay, caption=self.title, resizable=False)
        self.Display.set_location(self.xDisplay, self.yDisplay)
        pyglet.app.run()

game = runGame()

到目前为止一切都很好，一切正常。但从某种意义上说，我错了，既然我必须画一些东西，我该怎么办？从某种意义上说，Pyglet可以留在像Pygame这样的课程中吗？

标记的解决方案可能会解决问题 但是，在我看来，它并没有真正增加比你已经实现的功能更多的功能。

如果你真的想让Pyglet成为一个类，你实际上必须继承一些东西，或者利用以OOP方式编程的可能性进行重新调整。

这是我的两分钱：

import pyglet
from pyglet.gl import *
from collections import OrderedDict
from time import time

key = pyglet.window.key

class main(pyglet.window.Window):
    def __init__ (self, width=1024, height=576, caption="Pokémon Life and Death: Esploratori del proprio Destino", fps=True, *args, **kwargs):
        super(main, self).__init__(width, height, *args, **kwargs)

        platform = pyglet.window.get_platform()
        display = platform.get_default_display()
        screen = display.get_default_screen()

        self.xDisplay = int(screen.width / 2 - self.width / 2)
        self.yDisplay = int(screen.height / 2 - self.height / 2)
        self.set_location(self.xDisplay, self.yDisplay)

        self.sprites = OrderedDict()

        if fps:
            self.sprites['fps_label'] = pyglet.text.Label('0 fps', x=10, y=10)
            self.last_update = time()
            self.fps_count = 0

        self.keys = OrderedDict()

        self.mouse_x = 0
        self.mouse_y = 0

        self.alive = 1

    def on_draw(self):
        self.render()

    def on_close(self):
        self.alive = 0

    def on_mouse_motion(self, x, y, dx, dy):
        self.mouse_x = x
        self.mouse_y = y

    def on_mouse_release(self, x, y, button, modifiers):
        print('Released mouse at {}x{}'.format(x, y))


    def on_mouse_press(self, x, y, button, modifiers):
        if button == 1:
            print('Pressed mouse at {}x{}'.format(x, y))


    def on_mouse_drag(self, x, y, dx, dy, button, modifiers):
        self.drag = True
        print('Dragging mouse at {}x{}'.format(x, y))

    def on_key_release(self, symbol, modifiers):
        try:
            del self.keys[symbol]
        except:
            pass

    def on_key_press(self, symbol, modifiers):
        if symbol == key.ESCAPE: # [ESC]
            self.alive = 0

        self.keys[symbol] = True

    def pre_render(self):
        pass

    def render(self):
        self.clear()

        # FPS stuff (if you want to)
        self.fps_count += 1
        if time() - self.last_update > 1: # 1 sec passed
            self.sprites['fps_label'].text = str(self.fps_count)
            self.fps_count = 0
            self.last_update = time()

        #self.bg.draw()
        self.pre_render()

        for sprite in self.sprites:
            self.sprites[sprite].draw()

        self.flip()

    def run(self):
        while self.alive == 1:
            self.render()

            # -----------> This is key <----------
            # This is what replaces pyglet.app.run()
            # but is required for the GUI to not freeze
            #
            event = self.dispatch_events()

if __name__ == '__main__':
    x = main()
    x.run()

这样，您实际上可以与您的类进行交互，就好像它是pyglet类一样。例如，你得到on_key_press而不必使用装饰器等。

你应该为你正在做的每件事做更多的功能。例如，如果你想创建一行，你可能有

import pyglet, os

class runGame():
    widthDisplay = 1024
    heightDiplay = 576
    title = "Pokémon Life and Death: Esploratori del proprio Destino"

    wra = pyglet.image.load("wra.png")
    wrb = pyglet.image.load("wrb.png")

    def __init__(self):
        platform = pyglet.window.get_platform()
        display = platform.get_default_display()
        screen = display.get_default_screen()
        self.widthScreen = screen.width
        self.heightScreen = screen.height
        self.xDisplay = int(self.widthScreen / 2 - self.widthDisplay / 2)
        self.yDisplay = int(self.heightScreen / 2 - self.heightDiplay / 2)
        self.Display = pyglet.window.Window(width=self.widthDisplay,    height=self.heightDiplay, caption=self.title, resizable=False)
        self.Display.set_location(self.xDisplay, self.yDisplay)
        pyglet.app.run()

    def drawLine(x, y):
        drawLine(x, y)

你必须根据你想做的事情来制作这些功能，但是如果你在杀死程序之前没有多次使用runGame课程，你就不应该这样做。使用OOP编程并使用程序编程。

您可以通过继承pyglet.window.Window类来创建自定义pyglet窗口。之后在你的init方法中调用超类init（这将调用pyglet.window.Window类中的init）然后覆盖继承的方法（on_draw，on_key_press，on_key_release等）。之后创建一个更新方法，pyglet.clock.schedule_interval将在一秒钟内调用60次。最后只需调用pyglet.app.run（）方法。

import pyglet


class GameWindow(pyglet.window.Window):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

    def on_draw(self):
        self.clear()

    def on_mouse_press(self, x, y, button, modifiers):
        pass

    def on_mouse_release(self, x, y, button, modifiers):
        pass

    def on_mouse_motion(self, x, y, dx, dy):
        pass

    def update(self, dt):
        pass

if __name__ == "__main__":
    window = GameWindow(1280, 720, "My Window", resizable=False)
    pyglet.clock.schedule_interval(window.update, 1/60.0)
    pyglet.app.run()
