/*
AI有一些基本屬性可以用SetAIAttrib設定

SetAIAttrib(id, attrib, value);

AI 有四個行為狀態
1. Search
2. Lock
3. Pre-Attack
4. Attack
每種可以在_InitAI的時候用SetAIBehavior設定

SetAIBehavior(id, "type", typenum, rate, ...);

記得最後要call UpdateAIAttrib(id), 重新算機率
AI_SEARCH_FOLLOW最後一個參數要給follow的character id
AI_SEARCH_PATROL的patrol點就放在SetAIAttrib裡面設好,Behavior不再設
