我正在嘗試使用 tkinter 在 python 中撰寫一個簡單的游戲，其中一個塊跳過障礙物，但是我卡在了跳躍部分。每次呼叫跳轉函式跳得越來越慢，也不知道是什么原因。提前。
import time
import tkinter
import random
bg = "white"
f = 2
k=0
t = 0.01
groundLevel = 550
root = tkinter.Tk()
root.geometry("1000x600")
canvas = tkinter.Canvas(root,width = 1000,height = 1000,bg = bg)
canvas.pack(fill= tkinter.BOTH, expand= True)
posX = 50
posY= 530
startButton = tkinter.Button(canvas,text=" Start ")
def startPlayer(xx,yy):
canvas.create_rectangle(xx-20,yy-22,xx 20,yy 18,fill = "orange")
return(xx,yy)
def move(x,y,x2,y2,direction,fill,outline):
global f
#direction 0 = up
#direction 1 = down
#direction 2 = left
#direction 3 = right
if direction == 0:
canvas.create_rectangle(x,y,x2,y2,fill="cyan",outline="cyan")
canvas.create_rectangle(x,y-f,x2,y2-f,fill=fill,outline=outline)
if direction == 1:
canvas.create_rectangle(x,y,x2,y2,fill="cyan",outline="cyan")
canvas.create_rectangle(x,y f,x2,y2 f,fill=fill,outline=outline)
if direction == 2:
canvas.create_rectangle(x,y,x2,y2,fill="cyan",outline="cyan")
canvas.create_rectangle(x,y,x2,y2,fill=fill,outline=outline)
if direction == 3:
canvas.create_rectangle(x,y,x2,y2,fill="cyan",outline="cyan")
canvas.create_rectangle(x,y,x2,y2,fill=fill,outline=outline)
def playerJump():
global groundLevel, f, k,posX,posY,t
while k != 1:
move(posX-20,posY-22,posX 20,posY 18,direction = 0, fill = "orange",outline = "black")
posY -= 2
canvas.update()
if (posY) == 480:
k = 1
time.sleep(t)
k = 0
while k != 1:
move(posX-20,posY-22,posX 20,posY 18,direction = 1, fill = "orange",outline = "black")
posY = 2
canvas.update()
if (posY) == 530:
k = 1
time.sleep(t)
k = 0
def start():
canvas.create_rectangle(0,0,1000,600,fill="cyan")
canvas.create_line(0,550,1000,550,width = 3)
startButton.destroy()
startPlayer(50,530)
startGameButton = tkinter.Button(canvas, text ="Go!",command = playerJump)
startGameButton.place(x = 35, y=400)
return(startGameButton)
def resetButton():
global startGameButton
startGameButton.destroy()
startGameButton = tkinter.Button(canvas, text ="Go!",command = playerJump)
startGameButton.place(x = 35, y=400)
startImage = tkinter.PhotoImage(file="C:/Users/marti/OneDrive/Desktop/Wheel finder/startSign.png")
canvas.create_rectangle(0,0,1000,1000,fill="green")
startButton.config(image = startImage,command = start)
startButton.place(x = 130, y= 25)
canvas.create_rectangle(300,400,700,500,fill="#113B08",outline = "black",width = 3)
canvas.create_text(500,450,text = "By: --------", font = "Arial 30",fill ="white")
每次它運行時我都會縮短睡眠時間，這樣它會更快，但這只是一個臨時解決方案，它甚至沒有用。
uj5u.com熱心網友回復：
您的代碼的問題是您總是在畫布中添加新專案。當您跳躍時，您會更新橙色矩形并重新繪制其舊位置。然而，它們相互堆疊并且處理太多元素會使您的程式變慢。
我們創建播放器并將其回傳給主函式。
def startPlayer(xx,yy):
player=canvas.create_rectangle(xx-20,yy-22,xx 20,yy 18,fill = "orange")
return player
這是新的開始功能。檢查我們是否獲得了播放器并發送到 playerjump 函式。
def start():
canvas.create_rectangle(0,0,1000,600,fill="cyan")
canvas.create_line(0,550,1000,550,width = 3)
startButton.destroy()
player = startPlayer(50,530)
startGameButton = tkinter.Button(canvas, text ="Go!",command = lambda :playerJump(player))
startGameButton.place(x = 35, y=400)
return(startGameButton)
這是 playerjump 函式。我們得到 player 并發送到 move 函式。
def playerJump(player):
global groundLevel, f, k,posX,posY,t
while k != 1:
move(posX-20,posY-22,posX 20,posY 18,direction = 0, fill = "orange",outline = "black",player=player)
posY -= 2
canvas.update()
if (posY) == 480:
k = 1
time.sleep(t)
k = 0
while k != 1:
move(posX-20,posY-22,posX 20,posY 18,direction = 1, fill = "orange",outline = "black",player=player)
posY = 2
canvas.update()
if (posY) == 530:
k = 1
time.sleep(t)
k = 0
除了移動線，我沒有改變這個功能中的任何東西。
好的，現在讓我們檢查關鍵部分。
def move(x,y,x2,y2,direction,fill,outline,player):
global f
#direction 0 = up
#direction 1 = down
#direction 2 = left
#direction 3 = right
if direction == 0:
canvas.coords(player,x,y-f,x2,y2-f)
if direction == 1:
canvas.coords(player,x,y f,x2,y2 f)
if direction == 2:
canvas.coords(player,x,y,x2,y2)
if direction == 3:
canvas.coords(player,x,y,x2,y2)
看，我們沒有創建新的矩形，而是更新了現有的矩形。哪個更穩定
您還忘記了在代碼片段中添加 root.mainloop 。
