ParseError和不正確的座標

Question

我在我在龜中創建的遊戲遇到問題。每當我嘗試運行該程序時，都會收到回溯錯誤：ParseError: bad input on line 69 in main.py。但更早的時候（當錯誤沒有發生時）我的座標不能正常工作。我想我輸入了正確的，但它不起作用。在遊戲中你需要擊中果實。所以遊戲主要是這樣的：如果你錯過了水果，它應該從你的分數中取一分，在你的生命中取一分。起初它會檢查你是否沒有0分。如果你打到水果，你應該得到+1分。但令人遺憾的是，如果我在窗口左側的任何地方拍攝，我都會獲得+1分。不管距離如何。

中，我懷疑這個問題的代碼是：

def cannon_shooting(): 
    bullet1 = random.randint(1, 4) 
    global live_score 
    if live_score >= 100: 
    bullet1 = 5 
    if bullet1 == 1: 
    bullet.color('black') 
    if bullet1 == 2: 
    bullet.color('green') 
    if bullet1 == 3: 
    bullet.color('red') 
    if bullet1 == 4: 
    bullet.color('grey') 
    if bullet1 == 5: 
    bullet.color('white') 
    bullet.goto(cannon_x, -30) 
    bullet.showturtle() 
    bullet.goto(cannon_x, 130) 
    if bullet.ycor() == enemy.ycor() - 10: 
    if not bullet.xcor() == enemy.xcor() - 10: 
     if live_score == 0: 
     if live_score == 100: 
      score.color('white') 
     live_score = 0 
     score.clear() 
     if live_score >= 0: 
      score.write("Your score: %s" % live_score, font=(None, 11, "bold")) 
     else: 
     if live_score == 100: 
      score.color('white') 
     live_score = live_score - 1 
     score.clear() 
     if live_score >= 0: 
      score.write("Your score: %s" % live_score, font=(None, 11, "bold")) 
     move_speed = random.randint(1, 10) 
     lives = lives - 1 
    if bullet.xcor() = enemy.xcor() - 10: 
     if live_score == 100: 
     score.color('white') 
     live_score = live_score + 1 
     score.clear() 
     if live_score >= 0: 
     score.write("Your score: %s" % live_score, font=(None, 11, "bold")) 
     enemy1 = random.randint(1, 3) 
     move_speed = random.randint(1, 10) 
    if live_score == 100: 
    score.clear() 
    cannon.goto(0, -100) 
    cannon.hideturtle() 
    enemy.hideturtle() 
    bullet.hideturtle() 
    bullet.goto(0, -30) 
    win.color('green') 
    win.write("Congratulations!", font=(None, 20, "bold")) 
    win.goto(-140, -40) 
    win.write("You scored 100 points!", font=(None, 20, "bold")) 
    if lives == 0: 
    score.clear() 
    cannon.goto(0, -100) 
    cannon.hideturtle() 
    enemy.hideturtle()

    bullet.goto(0, -30)

Answer 1

問題是你說if bullet.xcor() = enemy.xcor() - 10:。 =用於分配，但不能在if塊中進行分配。您應該將其更改爲if bullet.xcor() == enemy.xcor() - 10:
