HTML+JavaScript飞机大战小游戏简易版
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
點(diǎn)擊開(kāi)始游戲后拖動(dòng)鼠標(biāo)在藍(lán)色區(qū)域內(nèi)即可操作飛機(jī)移動(dòng)
打中敵方得分,被敵方碰撞則減分掉血 運(yùn)用延時(shí)調(diào)用函數(shù)實(shí)現(xiàn)連續(xù)發(fā)射子彈 運(yùn)用隨機(jī)函數(shù)使敵方飛機(jī)在藍(lán)圖隨機(jī)刷新 運(yùn)用坐標(biāo)判斷子彈和敵方飛機(jī)距離,碰撞則消失,加得分 己方飛機(jī)圖:50px*50px (plane.png) 敵方飛機(jī)圖:32px*32px (zdj.png) 子彈圖:32px*32px, (zidan.png) 在HTML同層創(chuàng)建img文件夾,將圖放入,配合代碼則可運(yùn)行,圖片可更換,但是名字大小得一樣完整代碼
