Experience points

[SleepWalker]

Hi!
I'm planning a fighting and an experience point system,because I'm planning a MMORPG with the petsite script.The adopt must have a field named exp_points.You can increase the EXP with leveling.But there is an owner-only
function,fighting.The database will choose from different monsters.The chance of wins:your warrior's level is 5.If the monster's level:
-lower than the warrior's actual level -70% to win,30% to lose 20 EXP
-equals to the warrior's actual level - 50% to win,50% to lose 30 EXP
-higher than the warrior's actual level - 30% to win,70% to lose 30 EXP +10 EXP varies to the level highness,example a level 5 warrior defeats a lv.8 monster,he/she gets 60 EXP(30 EXP +30 EXP because the monsters level is higher with 3).If the warrior lose,he/she couldn't get any EXP.The monsters are need a field called adopts_monsters,and the fields are:
-monster_ID
-name
-level
.
Plus,somebody will fight at 36 times per day.
