PYGLET–可见形状

原文:https://www.geeksforgeeks.org/pyglet-shape-visible/

在本文中，我们将看到如何在 python 的 PYGLET 模块中访问形状的可见性。Pyglet 是一个易于使用但功能强大的库，用于开发视觉上丰富的图形用户界面应用程序，如游戏、多媒体等。窗口是占用操作系统资源的“重量级”对象。窗口可能显示为浮动区域，或者可以设置为充满整个屏幕(全屏)。形状是对象或其外部边界、轮廓或外部表面的形式，与颜色、纹理或材质类型等其他属性相反。许多形状都是借助 pyglet 的形状模块绘制的。Visible 属性告知形状是否应该可见。
我们可以借助下面给出的命令
创建一个窗口

# creating a window
window = pyglet.window.Window(width, height, title)


为了创建窗口，我们使用带有形状
的可见属性语法:形状.可见
参数:它不需要参数
返回:它返回 bool

下面是实现

Python 3

# importing pyglet module
import pyglet
# importing shapes from the pyglet
from pyglet import shapes
# width of window
width = 500
# height of window
height = 500
# caption i.e title of the window
title = "Geeksforgeeks"
# creating a window
window = pyglet.window.Window(width, height, title)
# creating a batch object
batch = pyglet.graphics.Batch()
# properties of rectangle
# co-ordinates of rectangle
co_x = 150
co_y = 150
# width of rectangle
width = 250
# height of rectangle
height = 150
# color = green
color = (50, 225, 30)
# creating a rectangle
rec = shapes.Rectangle(co_x, co_y, width, height, color = color, batch = batch)
# changing opacity of the rect1
# opacity is visibility (0 = invisible, 255 means visible)
rec.opacity = 180
# creating another rectangle with properties
# x, y co ordinate : 50, 250
# width, height of rectangle : 300, 200
# color = red
color = (255, 25, 25)
# properties of circle
# co-ordinates of circle
circle_x = 200
circle_y = 300
# size of circle
# color = green
size_circle = 100
# creating a circle
circle = shapes.Circle(circle_x, circle_y, size_circle, color =(250, 22, 30), batch = batch)
# changing opacity of the circle1
# opacity is visibility (0 = invisible, 255 means visible)
circle.opacity = 170
# window draw event
@window.event
def on_draw():
    # clear the window
    window.clear()
    # draw the batch
    batch.draw()
# accessing visible of rectangle
value_rec = rec.visible
# printing value
print("Rectangle : ", end = "")
print(value_rec)
# accessing visible of circle
value_cir = circle.visible
# printing value
print("Circle : ", end = "")
print(value_cir)
# run the pyglet application
pyglet.app.run()


输出:

Rectangle : True
Circle : True
