Battle Retry
Version 1.0
by Woratana
Release Date: 05/03/2009


Introduction
I saw this kind of script in Gamebaker before.
Now that site is temporarily close, so think it would be a good practice to write it myself.

What this script basically does is after player lose the battle and go to Gameover screen,
there will be a choice for player to choose whether to retry the battle again, or go to title screen.

This script can be enable/disable in game.
This way you can make player not be able to retry in specific battle.

You can also choose to record the party's HP/MP/state before battle.
Therefore, when player chose battle retry, party members will not have full HP/MP and have no bad status.

Enjoy~^^


Features
Version 1.0
- Set switch ID to enable/disable battle retry during the game
- Editable command's text, command's window width and Y-coordinate
- You can choose to record party actors stat (HP/MP/States) before battle

Bug Report?
Please give me these informations:

Quote- What is it says in error window?
- When is it get error? (Right after run game, when you choose something, etc.)
- What have you changed in setting part?
- Do you have any other scripts running in your game that may crash with this script?

Might use this, I'm testing it now.
Might come in handy if I do something like a battle arena.
Like if you lose a fight then you can retry as opposed to having to restart the event again.

Awesome script, Wora. Thanks :)

I have a question about this script. When I use the "Retry Battle" option, there is no battle music when the battle restarts. Do I have to set something specific for this or is this a known bug?

Oke Before I Download This I Got 1 Question...
When You Get Poisend In A Battle And You Defeat The Enemy
You  Will Stay In Poisen Condition And Lose HP...

So My Question Is When You Die In That Condition On Adventure What Will Happen
When You Retry Battle??

Hmmm okay since Wora seems to not be planning on updating this i'll contribute my crappy fix for the issue about not replaying Battle BGM

Here's the script with the Fix

Note: Credits go to Worana for the script i simply added 3 lines of text to it ^^''
Alternatively i think you can also remove one line but i'm too lazy to do that

What i changed?
Under Frame update i added:
          RPG::ME.fade(1000)
          RPG::ME.stop
          $data_system.battle_bgm.play
to the '#Setup Battle' part of the Script
i guess one could also remove the Music Effect Fade since it will stop anyways so the fade is kinda useless.

WARNING: In my Script the Record Party State is on False and the Switch ID is 196 ^^ so if you don't wish to be fully healed at retry or use another switch id you need to change that ^^
