** script to prevent creature experience reduction due to overflow. JHV,2/3/2009
** uses v7090-v7103 to store troop ranks @ start of battle
** uses FU459-FU462
**"The bug you describe probably occurs when the experience exceeds the maximum
**positive value that its (internal) variable can store.
**For example, one byte (8 bits) can store a number from
**0 to 255 (11111111 in binary), but it is convenient to the value stored as
**from -128 to +127, by performing the "two's complement" (change all 0's to 1's
**and 1's to 0's, then add 1) to convert a positive number to a negative number,
**because any binary number and its two's-complement sum to zero (with a carry
**that overflows out of the byte).  This makes integer subtraction easy (just add
**the two's complement of the number to be subtracted), but it means that, for
**example, if you are using 1-byte storage, adding 2 to
**127 (00000010 to 01111111 in binary) produces -127 instead of 129."
**In readable words :P this bug will certainly occur when the experience received
**after a very big battle can't be handled by the game. Usually if you continue
**to play a map after the 12th month and the neutral creatures have an
**overgrowth. Your experience will go into the negative, all abilities will be
**lost and you will need certainly more than hundred battles to restore it.
**The script restore it automatically if lost.

看起来像是修复经验溢出的脚本

无心云

现在高人中好像也就风侠出现的频率高点了

加油啊，大仙们，出现吧

ＬＺ我来解释一下．看行不？
!?BA0&1000; 战斗开始前并双方有一方不是电脑就促发一下事件．
!!BA:H0/?v1; 得到攻方雄号码Ｖ１
!!BA:H1/?v2; 得到防方雄号码Ｖ２
!!DO459/0/6/1&v1>-1/v1<156:Pv1; 当Ｖ１＞－１且Ｖ１＜１５６就引发！？ＦＵ４５９并让他运行６次．并让！？ＦＵ４５９后的Ｘ１＝Ｖ１

!?BA1&1000; 战后．并双方有一方是非电脑就开使下面事件
!!BA:H0/?v1; 得到攻方雄号码Ｖ１

!!BA:H1/?v2; 得到攻方雄号码Ｖ２

!!VRv3:C-1/-1; 让Ｖ３＝－１　Ｖ４＝－１
!!HEv1&v1>-1/v1<156:O?v3; 当Ｖ１＞－１且Ｖ１＜１５６．就取Ｖ１号英雄的归属．
