In my game, I’d like to have a poison state that decreases Hp or Mp my a percentage every second in battle.

So far, I’ve tried doing this by creating a parallel processing common event that decreases Hp/mp per second, but this only works outside of battle, I’d like it to work in battle. Preferably, I’d also like to players to be able to see the Hp/mood bar drain overtime when fixable during battle too.

Any ideas on how to implement this? Any help is much appreciated.

are you referring to MP/HP or MMP/MMP? If the former, then the best way would be to make a poison state, and have the state set HRG/MRG to a negative number. This doesn't decrease every second, but it does decrease every turn.

Just HP/MP.
I am aware you can set a state to decrease HP or MP every turn, but I’d like it to decrease every second (maybe see the bar drain in real time?) So far I can do this outside of battles with a parallel process, not in battles. Thanks for your help though!

Himeworks global common event seems to do the trick, although I couldn't get the bars to update in real time, but the bars do update whenever a selection is made or any general interaction happens.

You'd have to use an ATB battle system and have tick effects (DoTs and HoTs) do damage or healing every second.

Thanks! Would you be willing to point me in the right direction on how to do this?

I haven't used VX Ace in such a long time. There are a few different ATB systems out there for it, but I wouldn't know which one would be best for you.

Let me present the problem of having this in your project. First, the code.
Code:
class Scene_Battle
 
  alias update_basicx update_basic
  def update_basic
    update_basicx
    $game_party.update
  end
 
end

class Game_Party
  def update
    members.each {|m| m.update_rt_hrg }
  end
end

class Game_Actor
  def update_rt_hrg
    if state?(2)
      self.hp -= 1 
      SceneManager.scene.refresh_status
      if $imported["YEA-BattleEngine"]
        SceneManager.scene.status_redraw_target(self)
      end
    end
  end
end
I use state 2 as an example. You can try it on your own.

First, each frame update will reduce the actor's HP by 1. So one second it will be reduced by 60. You might not want it. So you might need to think the reduction rate. On one second or 60 frames, how much the HP will be actually reduced?

Second, repeatedly redrawing HP bar is time consuming and may cause lag. This can't be fixed without reworking almost entire window actor status. So you need a custom HUD as well to make the process more efficient.

Third, during the attack animation, it will also be reduced. The longer the animation is, the more draining the state. Are you sure you want this to happen?

Just tested and it works as intended. Thanks! This is more or less the idea I wanted. I realize the potential of the draining taking place even during animations, and that's completely fine.

Although I'd like the decrease to happen every second instead of every frame. Is is possible to alter the delay time?

Line 19, change it to
Code:
if state?(2) && Graphics.frame_count % 60 == 0
I'm such lazier, probly some of scripters would scold me.

Hello.
The rules I makes pun about on your last thread is about "Verify Files" before anything else, if the stuff comes from STEAM. Which means, if it could be fixed with just that, there is no need to redownload the whole stuff.
But glad the reinstall worked, hope you enjoy it and your days too.
uh oh, I just tapped into a fresh, deep vein of nightmare fuel right here guys:
