因項目需要，人物30多個，每個人物動畫以及命名都是一樣。新版的動畫系統(tǒng)Mecanim，支持連線之類，想在新項目中使用。但是讓策劃一個個手動去連線，設(shè)置觸發(fā)條件太麻煩了也容易出錯。（初步我們有4個動作 "walk", "idle", "attack", "skill"，四個動作可以直接相互切換）

網(wǎng)上沒找到類似的代碼。。于是寫了個簡單的插件來處理。直接上代碼。。這個就自動連線和設(shè)置里面的條件了。
先搜索整個目錄下的fbx文件（動作和模型做到一起去了），然后根據(jù)制定的幾個動作，自動生成狀態(tài)機，包括設(shè)置好觸發(fā)條件。
