I would like to request a script similar to romancing saga's BP system (battle points)

so what is battle points? instead of using MP (the game don't have one) BP is used in performing weapon-based and magical skills (in short all types of skills)

let's cite an example:

5/10 +3

5 - the starting BP of a certain char
10 - max BP you will get
+3 - regen of BP every after turn

here's how it works, since you only have 5 bp at start, if you didn't used it up it will become 8 (+3 regen) or if you used it up just sum up the +3 regen. guard, attack and using items are considered not consuming BP. if you use a skill for example costs 3 BP therefore the remaining BP will be 2 (+3 regen) when it's your turn again it will be 5

also additional features:

1) when ko'd BP resets to the starting BP
2) the starting bp and max bp raises as you lvl up (regen doesn't but some equipment can and regen can also be increased in terms of 50% of max bp so i guess it's affected by lvl up)
3) each character is unique (for example high starting/low max bp and so on)

another example:
http://www.rpgamer.com/games/saga/rsms/screens/rsms180.jpg

see in the pic, (below is the bp window then disregard the DP, splash shot costs 3 BP since she has 8 she can perform it, when she used it up her remaining will be 8bp(starting bp) - 3bp(splash shot) = 5bp +3regen(when you turn again) = 8bp again yes it can be spammed but what if that skill is weak and the stronger skill is id break which costs 7bp? the computation then will be 8bp - 7bp(id break) = 1bp + 3 regen = 4bp, therefore you can't use id break again and use either attack, item, guard to gain bp again

in short, this is a diff. way of the mp system which is quietly good since you will manage and spend wisely your bp instead of spamming skills with the mp system

i hope someone can make this i'll greatly appreciate it
