PYGLET – 访问 Sprite 批次

在本文中，我们将看到如何在Python的 PYGLET 模块中访问 sprite 的批处理对象。 Pyglet 是易于使用但功能强大的库，用于开发视觉丰富的 GUI 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。 Windows 可能显示为浮动区域，也可以设置为填充整个屏幕（全屏）。精灵是在屏幕上显示的图像的一个实例。多个精灵可以在屏幕的不同位置显示相同的图像。精灵也可以放大或缩小，以任何角度旋转，并以分数不透明度绘制。图像是在 pyglet 的图像模块的帮助下加载的。精灵可以从一个批次迁移到另一个批次，或从其批次中移除（用于单个绘图）。请注意，这可能是一项昂贵的操作。

我们可以在下面给出的命令的帮助下创建一个窗口和精灵对象

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

# creating a sprite object
sprite = pyglet.sprite.Sprite(img, x, y)

In order to create window we use batch attribute with sprite object
Syntax : sprite.batch
Argument : It takes no argument
Return : It returns batch object

编程需要懂一点英语

下面是实现

Python3

# importing pyglet module
import pyglet
import pyglet.window.key as key
    
# 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)
    
# text 
text = "Welcome to GeeksforGeeks"
   
# creating label with following properties
# font = cooper
# position = 250, 150
# anchor position = center
label = pyglet.text.Label(text,
                          font_name ='Cooper',
                          font_size = 16,
                          x = 250, 
                          y = 150,
                          anchor_x ='center', 
                          anchor_y ='center')
  
  
# creating a batch
batch = pyglet.graphics.Batch()
  
# loading geeksforgeeks image
image = pyglet.image.load('gfg.png')
  
# creating a list of sprites object
sprites = []
  
# position of images
pos_x = 10
pos_y = 230
  
for i in range(5):
      
    # temporary sprite object
    temp = pyglet.sprite.Sprite(image, pos_x, pos_y, batch = batch)
      
    # append the sprite object to the list
    sprites.append(temp)
      
    # increment the x co-ordinate
    pos_x = pos_x + 100
  
  
# on draw event
@window.event
def on_draw():
        
    # clear the window
    window.clear()
        
    # draw the label
    label.draw()
      
    # draw the batch
    batch.draw()
        
# key press event    
@window.event
def on_key_press(symbol, modifier):
    
    # key "C" get press
    if symbol == key.C:
          
        # printing the message
        print("Key : C is pressed")
          
# image for icon
img = image = pyglet.resource.image("gfg.png")
  
# setting image as icon
window.set_icon(img)
     
     
# getting batch of the first sprite
sprite = sprites[0]
value = sprite.batch
 
# setting this value to the label
label.text = str(value)
 
 
# start running the application
pyglet.app.run()

输出：
