PYGLET – 精灵 X 和 Y 坐标
在本文中,我们将看到如何在Python的 PYGLET 模块中访问精灵的 X 和 Y 坐标。 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 X 和 Y 坐标是精灵在 x 轴和 y 轴上的位置。
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 x and y attribute with sprite object
Syntax : sprite.x and sprite.y
Argument : It takes no argument
Return : It returns integer
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 sprite object
# it is instance of an image displayed on-screen
sprite = pyglet.sprite.Sprite(image, x = 200, y = 230)
# on draw event
@window.event
def on_draw():
# clear the window
window.clear()
# draw the label
label.draw()
# draw the image on screen
sprite.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)
# accessing x, y co-ordinates of the sprite
value_x = sprite.x
value_y = sprite.y
# creating text from value
text = "X & Y co-ordinates : " + str(value_x) + ", " + str(value_y)
# setting text to the label
label.text = text
# start running the application
pyglet.app.run()
输出 :
