所以我正在制作小行星并且它还处于早期阶段。我有一个按钮,但命令功能不会在同一个类中调用该函数。这是代码:
class parentWindow():
def play(self,master):
print("PARTY")
def __init__(self,master):
self.master=master
self.master.title("Asteroids")
self.background_image = PhotoImage(file = "Stars.gif")
self.canvas = Canvas(self.master, width = 1920, height = 1080, bg = "black")
self.canvas.image = self.background_image
self.canvas.pack(expand = YES, fill = "both")
self.canvas.create_image(0,0, image= self.background_image, anchor = NW)
label1 = Label(text="ASTEROIDS", fg="white", bg="black", height=3, width=10)
label1.config(font=("arcadeclassic", 50))
label1.place( x=775, y=200)
button1 = Button(text = "Play", command= play)
button1.place( x=900, y=600)
当我运行这个(以及其余的)时,我会看到“Play is not defined”。谢谢你的帮助!
答案 0 :(得分:1)
您需要使用全名:
button1 = Button(text = "Play", command=self.play)
仅此一项就会给你一个新的错误,因为' play'期待一个"大师"论点。您需要将播放功能更改为仅需要单个参数:
def play(self):
print("PARTY")
