"Before/After Battle Common Event Activator" Script

Hello everyone!

To make a short story, I made a few games on RMXP about 5 years ago. I remember having a script I would use to run common events before battle, such as for giving special bonuses for a fight, testing if a thief would have a free backstab, etc.. I would also use that script after battle to regen a few HP/MP with a skill and adjust a few variables and switches.
A few years ago, I developed the itch to make a new game, then I finally cracked and acquired RMVX. I've looked here and on other sites but I can't seem to find a script like I just described for RMVX. Does such a script exist? If not, is it okay to [Request] it in the proper place?

Thanks

This should let you run a common event before and after battle.

  def battle_common_event(id)
    common_event = $data_common_events[id]
    if common_event != nil
      @child_interpreter = Game_Interpreter.new(@depth + 1)
      @child_interpreter.setup(common_event.list, @event_id)
    end
    return true
  end
end


To use simply edit these constants in the script.

Code: [Select]

  BEFORE_BATTLE_C_EVENT_ID = #


# Is the ID of the common event you want to run before battles.

Code: [Select]

  AFTER_BATTLE_C_EVENTS_ID = [#1, #2, #3]


After battle you can set 3 different common events to run depending on what happened in battle.

#1 ID of common event to run if you win
#2 ID of common event to run if you escape
#3 ID of common event to run if you lose

If you set the ID of any to 0 it won't run any common events in that instance.

Let me know if this works out for you and if you need anything fixed/added.

Have a nice day.

The script was loaded and tested, it worked perfectly. Thanks a lot! Good thinking on splitting up the three possible outcomes, if I remember correctly the RMXP version ran the same script whatever the battle result was.

For now, I don't have anything in mind that I would like to add/modify, but I'll be sure to drop a line if I think about something.

Thanks again and have a nice day too!
