在游戏运行时更改文本内容-Python Arcade 2.4.3
我正在寻找一种在游戏运行时更改渲染文本的方法 我发现有人说只需更改文本变量就可以了 所以我试着这样做:在游戏运行时更改文本内容-Python Arcade 2.4.3,python,python-3.x,text-rendering,arcade,Python,Python 3.x,Text Rendering,Arcade,我正在寻找一种在游戏运行时更改渲染文本的方法 我发现有人说只需更改文本变量就可以了 所以我试着这样做: import arcade WINDOW = {"width":800, "height": 600, "title": ""} class MyGame(arcade.Window): """ Main application class. "&
import arcade
WINDOW = {"width":800, "height": 600, "title": ""}
class MyGame(arcade.Window):
"""
Main application class.
"""
def __init__(self):
# Call the parent class and set up the window
super().__init__(WINDOW['width'], WINDOW['height'], WINDOW['title'])
arcade.set_background_color(arcade.csscolor.CORNFLOWER_BLUE)
def setup(self):
""" Set up the game here. Call this function to restart the game. """
pass
def on_draw(self):
""" Render the screen. """
arcade.start_render()
# Code to draw the screen goes here
self.text = "Hello world!"
arcade.draw_text(self.text, WINDOW['width'] / 3 + (WINDOW['width'] / 3 / 3) - 20, WINDOW['height'] / 2, arcade.csscolor.WHITE, 18)
def on_mouse_release(self, x, y, button, key_modifiers):
print("Clicked!")
self.text = "Clicked!"
def main():
""" Main method """
window = MyGame()
window.setup()
arcade.run()
if __name__ == "__main__":
main()
但是,文本仍然没有改变,但它可以检测到点击。arcade.run()
运行循环,该循环在此循环中对绘图()执行。如果代码以每秒25帧的速度运行,那么它将每秒执行25次。因此,当您单击鼠标时,鼠标释放()上的将文本更改为“单击!”
,然后在绘图()上的将其更改回“Hello world!”
,最后显示“Hello world!”
您应该使用中的self.text=“Hello world!”
或设置()中的(更好)只设置一次
import arcade
WINDOW = {"width":800, "height": 600, "title": ""}
class MyGame(arcade.Window):
"""
Main application class.
"""
def __init__(self):
# Call the parent class and set up the window
super().__init__(WINDOW['width'], WINDOW['height'], WINDOW['title'])
arcade.set_background_color(arcade.csscolor.CORNFLOWER_BLUE)
def setup(self):
""" Set up the game here. Call this function to restart the game. """
self.text = "Hello world!"
def on_draw(self):
""" Render the screen. """
arcade.start_render()
# Code to draw the screen goes here
arcade.draw_text(self.text, WINDOW['width'] / 3 + (WINDOW['width'] / 3 / 3) - 20, WINDOW['height'] / 2, arcade.csscolor.WHITE, 18)
def on_mouse_release(self, x, y, button, key_modifiers):
print("Clicked!")
self.text = "Clicked!"
def main():
""" Main method """
window = MyGame()
window.setup()
arcade.run()
if __name__ == "__main__":
main()
以下是单击鼠标更改文本的简短示例:
import arcade
class Game(arcade.Window):
def __init__(self):
super().__init__(400, 300)
self.text = 'Waiting for click!'
def on_draw(self):
arcade.start_render()
arcade.draw_text(self.text, 200, 150, arcade.color.RED, 18, anchor_x='center')
def on_mouse_release(self, x, y, button, key_modifiers):
self.text = 'Clicked!'
Game()
arcade.run()
输出:
on_draw()
将self.text
设置为“Hello world!”
,因此您在中对鼠标释放()所做的任何更改都将被丢弃。正如@PranavHosangadi已经说过的-您不应该将self.text=“Hello world!”
放在on_draw()
中,而应该放在中。这样,它将仅在开始时设置为“Hello world!”
。稍后按钮会将其更改为“单击!”
。您必须记住,arcade.run()
在每个循环中运行在绘图()上执行的循环。
