一构回、題目要求
最近在聽funk音樂(lè)陈惰，感覺真?zhèn)€人都舒服了，些這個(gè)作業(yè)的時(shí)候身體一直在抖,這次要完成的作業(yè)是參考《代碼本色》教程禀挫，運(yùn)用不少于3個(gè)章節(jié)的動(dòng)畫技術(shù)旬陡，實(shí)現(xiàn)一個(gè)交互應(yīng)用，將動(dòng)畫技術(shù)充分運(yùn)用于交互過(guò)程中语婴；
做了一個(gè)小游戲描孟，
整個(gè)游戲的玩法就是通過(guò)鼠標(biāo)控制粉色小球移動(dòng)驶睦，小的方塊是食物，可以被吃掉匿醒，其他的的大球是怪物了场航，如果他們碰到你就會(huì)減分?jǐn)?shù)并且會(huì)卡頓，分?jǐn)?shù)顯示在左上角
背景是聲音的波動(dòng)廉羔，加載了一首bgm溉痢，會(huì)根據(jù)節(jié)奏抖動(dòng)，其實(shí)可以使怪物的移動(dòng)也和音樂(lè)結(jié)合起來(lái)憋他，但是奈何太懶了孩饼，暫時(shí)就這樣了。
其實(shí)代碼并沒有多復(fù)雜了竹挡，比較復(fù)雜的地方是怪物的成長(zhǎng)是根據(jù)基因模擬的镀娶，每個(gè)怪物一開始都會(huì)隨機(jī)初始的基因，根據(jù)基因來(lái)繪制大小此迅，有一定幾率分裂和隨機(jī)產(chǎn)生汽畴，然后個(gè)體生命會(huì)隨著時(shí)間衰減，當(dāng)他們碰到玩家控制的小球后就會(huì)重新變得滿生命值
二耸序、實(shí)踐內(nèi)容
