本文小編為大家詳細(xì)介紹“Python如何實(shí)現(xiàn)射擊闖關(guān)游戲”，內(nèi)容詳細(xì)，步驟清晰，細(xì)節(jié)處理妥當(dāng)，希望這篇“Python如何實(shí)現(xiàn)射擊闖關(guān)游戲”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學(xué)習(xí)新知識吧。
地圖編輯器：可以實(shí)現(xiàn)玩家自己定義每一關(guān)卡的樣式和難易程度
運(yùn)行界面：實(shí)現(xiàn)了玩家的移動，跳躍，發(fā)射子彈，投擲手雷，以及敵人的AL（移動，發(fā)射子彈，扔手雷），同時(shí)游戲中有一系列的道具（生命值藥箱，子彈補(bǔ)給，手雷補(bǔ)給）以及各種動畫和音樂音效，還有各種花草巖石裝飾品，以及懸崖和水渦危險(xiǎn)地方，更多未知，自己體驗(yàn)就能感受到！
總代碼累計(jì)1100行左右！
