Do you want the spell to regenerate TP instantly or by a certain amount of turns. Like over the next 3 turns each player regains some TP.

I wanted to make a spell which regenerate TP next few turns.
karins gave me a perfect answer but I appreciate your help too!

It's possible!
Assuming that the said spell will inflict a specific state (that applies the random TRG), this will do the job:
class Game_Battler < Game_BattlerBase
def regenerate_tp
state_id = 1 # The ID of the state to be used
min = 0 # The minimum amount of TP to be restored
max = 100 # The maximum amount of TP to be restored
self.tp += self.state?(state_id) ? (min + rand(max)) : 100 * trg
end
end

karins,you perfectly solved the problem.
Thank you for your help!

I tried your method with a new project and everything worked fine.
My current project has too many scripts and I should remove some of them.
Anyway,My major problem was solved.
Thank you for helping me many times :)

Thank you for your advices.
The error didn't occur when I tried the script karins made.
It weakened enemies in a back row but weakened enemies in a front row too...
I think all the problems should be solved if I correctly take your advices.
Do you know why the enemies in the front row were weakened?

I divide enemies into two groups with a script.
Some enemies are in front rows and the rest of enemies are in back rows.
The script basically works pretty well but the enemies in the back rows always deal the same damage as the enemies in the front rows do.
I want to know how I can weaken ATK of the enemies in the back rows.

The problem is solved by Deltree's solution.
Thank you for your answers!
You seem to have a lot of knowledge about scripts and I want to ask a question.
There's no visual clue if an enemy is in a front row or in a back row.
So I want to put icons to enemies in a front row.
I asked the creator of the script about this and he answered

Each battler (enemy and ally) has battle_row variable, which hold it's row. 0 is Front and 1 is back.
So something like this would check if first member of the party is in front row

if $game_party.members.battle_row == 0
# 1st member is in front. Do stuff
end

I still don't know how to put icons to enemies in a front row...
Please tell if you know how to add visual clues to enemies in a front row.
