Question

在开发游戏时，添加了将窗口尺寸从800 x 600调整为任意大小的功能。这样，我失去了GUI按钮的功能。我怀疑导致该问题的潜在变量是按钮的center_x，center_y，宽度，高度。

当我使用按钮的大小来检查输入时，宽度和高度不太可能会引起问题，按钮的大小会像屏幕一样缩放。我检查的职位却无法扩展。

因此，可能有许多解决此问题的方法，但是我能想到的最简单的方法是：创建按钮实例时，请使用可缩放的变量，而不是不能缩放的变量。

所以不是（center_x，center_y，宽度，高度）：

play_button = StartTextButton(60, 570, 100, 40)

类似：

play_button = StartTextButton((SCREEN_WIDTH * ? %), (SCREEN_HEIGHT * ? %), 100, 40)

内在的问题：

1）如何计算按钮的center_x / y以屏幕宽度/高度的百分比表示？

2）如何将像素转换为相对于尺寸的屏幕坐标？

3）是否有更容易忽略的解决方案？

4）无论如何，更简单的方法来决定在何处放置按钮？

感谢任何反馈/帮助。干杯！

检查按钮点击的代码：

def check_mouse_press_for_buttons(x, y, button_list):
    """ Given an x, y, see if we need to register any button clicks. """
    for button in button_list:
        if x > button.center_x + button.width / 2:
            continue
        if x < button.center_x - button.width / 2:
            continue
        if y > button.center_y + button.height / 2:
            continue
        if y < button.center_y - button.height / 2:
            continue
        button.on_press()

def check_mouse_release_for_buttons(x, y, button_list):
    """ If a mouse button has been released, see if we need to process
        any release events. """
    for button in button_list:
        if button.pressed:
            button.on_release()

可从Arcade库调整窗口大小的可运行代码示例：

"""

If Python and Arcade are installed, this example can be run from the command line with:
python -m arcade.examples.resizable_window
"""
import arcade

SCREEN_WIDTH = 500
SCREEN_HEIGHT = 500
START = 0
END = 2000
STEP = 50


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

    def __init__(self, width, height):
        super().__init__(width, height, title="Resizing Window Example", resizable=True)

        arcade.set_background_color(arcade.color.WHITE)

    def on_resize(self, width, height):
        """ This method is automatically called when the window is resized. """

        # Call the parent. Failing to do this will mess up the coordinates, and default to 0,0 at the center and the
        # edges being -1 to 1.
        super().on_resize(width, height)

        print(f"Window resized to: {width}, {height}")

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

        arcade.start_render()

        # Draw the y labels
        i = 0
        for y in range(START, END, STEP):
            arcade.draw_point(0, y, arcade.color.BLUE, 5)
            arcade.draw_text(f"{y}", 5, y, arcade.color.BLACK, 12, anchor_x="left", anchor_y="bottom")
            i += 1

        # Draw the x labels.
        i = 1
        for x in range(START + STEP, END, STEP):
            arcade.draw_point(x, 0, arcade.color.BLUE, 5)
            arcade.draw_text(f"{x}", x, 5, arcade.color.BLACK, 12, anchor_x="left", anchor_y="bottom")
            i += 1


def main():
    MyGame(SCREEN_WIDTH, SCREEN_HEIGHT)
    arcade.run()


if __name__ == "__main__":
    main()

失去重新调整窗口大小的功能和更简单的计算坐标的方式？
