我正在嘗試使用 Pygame 為學校制作一個空閑唱首歌游戲，我遇到了一些問題，我真的很感激一些幫助
我想在當前敵人的 hp 達到 0 時替換螢屏上的敵人，但是當我在敵人 HP 達到 0 時繪制第二張影像時，第一張影像沒有被替換，有人可以幫我解決這個問題嗎
提前致謝

uj5u.com熱心網友回復：
[這是我的第一個回答，請給我一點懈怠]
在顯示精靈時，跟蹤您正在顯示的精靈是至關重要的。當前代碼最干凈的解決方案是使用跟蹤變數，如“currentGoblin”。
currentGoblin = 0
每次你的地精被殺死時，將該變數增加 1。現在，渲染你的精靈。洗掉goblin2.draw()，沒必要。在您繪制第一個精靈（地精）的地方，將代碼替換為：
if currentGoblin == 0:
goblin.draw(menuScreen.screen)
elif currentGoblin == 1:
goblin2.draw(menuScreen.screen)
# etc, so you can add more goblin images
您的代碼的缺陷在于您不會永久更改影像/精靈，直到它重新顯示。
本質上，此修復所做的是顯示您正在處理的任何地精，并在它被殺死時移動到下一個。
