livingobject.js / frame transition

any frame transition caused by any event is delayed until the end of a TU to take effect. this is to maintain the isochronous nature of the game clock and to allow synchronization over network.
as a consequence, there can be many frame transition attempts in a TU.

to resolve frame transition conflicts, F.LF introduces a frame transition lock.
each attempt in causing a frame transition will set a lock to its authority, and late comers can only override the frame transition if they have a higher or equal value than the current lock.

任何事件引起的frame transition都會延遲至TU的完結才發生. 這是為了保持遊戲的等時性, 及同步性.
所以, 一個TU之內可以有多於一個frame transition發生.

去化解frame transition衝突, F.LF 用了一個 frame transition lock.
任何事件製造frame transition的時候, 都需要提供一個權限(越大越勁), 去鎖住transition lock, 只有大於或相等權限的event才可以修改transition lock.
