因項(xiàng)目需要，人物30多個(gè)窗悯，每個(gè)人物動(dòng)畫(huà)以及命名都是一樣区匣。新版的動(dòng)畫(huà)系統(tǒng)Mecanim，支持連線(xiàn)之類(lèi)蒋院，想在新項(xiàng)目中使用亏钩。但是讓策劃一個(gè)個(gè)手動(dòng)去連線(xiàn)，設(shè)置觸發(fā)條件太麻煩了也容易出錯(cuò)欺旧。（初步我們有4個(gè)動(dòng)作 "walk", "idle", "attack", "skill"姑丑，四個(gè)動(dòng)作可以直接相互切換）

網(wǎng)上沒(méi)找到類(lèi)似的代碼。辞友。于是寫(xiě)了個(gè)簡(jiǎn)單的插件來(lái)處理栅哀。直接上代碼震肮。。這個(gè)就自動(dòng)連線(xiàn)和設(shè)置里面的條件了留拾。
先搜索整個(gè)目錄下的fbx文件（動(dòng)作和模型做到一起去了）戳晌，然后根據(jù)制定的幾個(gè)動(dòng)作，自動(dòng)生成狀態(tài)機(jī)间驮，包括設(shè)置好觸發(fā)條件躬厌。
