マウスのクリックで矢印を発射しようとしていますが、マウスの方向に向かっています。私は射撃部分を達成しましたが、私はそれをマウスに向かって撃つことはできません。私は下に私のコードを記載して、本当にすべての助けに感謝！マウスの方向に矢を撃つ方法は？
矢印撮影に関連するコードの一部は次のとおりです。
for shot in daggers:
index = 0
shotx = math.cos(shot[0])*35
shoty = math.sin(shot[0])*35
shot[1] += shotx
shot[1] += shoty
if shot[1] < -40 or shot[1] > 900 or shot[1] < -40 or shot[1]> 600:
daggers.pop(index)
index =+ 1
for shoot in daggers:
daggerOne = pygame.transform.rotate(daggerPlayer, 360 - shoot[0]*57.29)
screen.blit(daggerOne, (shoot[1], shoot[1]))
pygame.display.update()

私は私の元のコードにこれを組み込むしかしとき、どうもありがとうございました。戻りショット[0] <-40またはショット[0]> 900またはショット[1] <-40またはショット[1]> 600 TypeError： 'float 'オブジェクトはサブスクリプトではありません' – Student
つまり、浮動小数点を 'outOfBounds'関数に渡していますが、' shot [0] 'のような角括弧を使うことができるように、サブスクリプト化可能なタプルやリストが必要です。関数内のshot [0] 'はx座標で、' shot [1] 'はy座標です。変数out_of_bounds内の変数/パラメータ名を編集して明確にします。 – skrx
