(RPGMaker VX Ace) Playing a BGM when actor's HP is low... OUTSIDE of battle?

Hello!

I've been playing around with events but I just can't seem to get past this one thing: Playing a BGM when Actor's HP falls below a threshold OUTSIDE of battle... or normal BGM resumes when HP goes above. 

I've combed the forums and google but seemingly to no avail. I've tried conditional branches, variables and  still nothing seems to work.

I'd assume I'd need to create a common parallel process event for this...

Am I missing something here...?

I hope this is specific enough. Thanks for your time and thanks in advance!

Edit: There's no battle system in the game so the HP would stay the same--well, the so-called 'danger zone' would be the same, anyway.  The max HP isn't anything astronomical, like 30 HP if that. Hope this helps!

Well,Actually i just tried something and i find a solution

So,Let's say the Actor's HP Is 562HP

And you will fight 2 slimes

So what i did was make some npc and i will fight 2 slimes and turned the switch on after the fight



And i made an event which auto runs when HP Music on switch is on

So

the event contained that it controlled a variable Which Is singe in HP And its operation is adding and game data is Actor : Eric's HP

then u make a condtional branch and choose variable HP Less than or equal to the hp u want when the music is played

so i will play the music when hp is constant 550 then i  added the function where i play the music i want then erase event

then leave the ELSE Blank

Simply,what i did is in this picture



i think in second picture u can actually disable the variable idk why i enabled it o_O

I Hope u understand anything, i am not really good in explaining

The good news is... that takes care of HALF my problem! :)

The bummer news...

Now, I'm trying to figure out how to set the BGM back to normal when HP goes back up to a decent number. I can't select just one BGM because there are several... so this situation seems a bit dicey still.

Here's my idea:
Make event be a Parallel Process.

>Loop
>Change Variable to be Hero's HP, multiply for 100 then divide for MaxHP
>Conditional Branch: Variable less or equal to 25
>>Conditional Branch: Switch LowHP is OFF

>>>Save BGM

>>>Play BGM (yourmusichere)

>>>Switch LowHP On

>else
>>Conditional Branch: Switch LowHP is ON

>>>Replay BGM

>>>Switch LowHP Off
>Wait 5 frames
>endLoop

This is my version, but as you can see it isn't in english...

I Think it goes the same idea

U Make the condtional thing,so when HP Is what ever u want when its normal,lets say it was 100 when its bad and on 500 its good u play the BGM.

How do u play the bgm?

Make that when the condtional branch of the actor is 500 it turns on a switch that plays back another bgm and make that another event when the switch is turned on it turns on,easy :D

if you cant do it just add me on  skype : mevoleproductions 

Thanks again, guys. I'll go ahead and try it out. I'll edit this post later and tell you how it worked.

EDIT:

@Waterguy, I copied the event exactly and the game froze! o_o  Not permanently, though...

Whenever I start a new game, the screen goes black and freezes.

Oh dear...

EDIT 2: I'm an IDIOT! 

I figured out what I did wrong. I put the ELSE in the wrong conditional branch.  Also, I did everything without a loop.    

Now... the final test: Putting this as a parallel common event. If this works, I'll report the thread as solved! Here goes...

EDIT 3: Taking it out of the loop and putting it as a parallel common event doesn't work... Let's try it INSIDE the loop now...

=======================================

EDIT 4: It works FLAWLESSLY, just as you put....      ...However, it only works as an event, not as a comment Parallel process COMMON event... So, when I leave one room, the event doesn't trigger... only when I'm in that certain room will it trigger...

Is there a way to successfully put this as a common event, or will I need to add the event to every room/field of the RPG where there will be enemies?

What about my solution o_O?

@Mevo, sorry bout that. That was actually the first thing I tried.  The BGM did this weird skipping thing... absolutely terrifying... haha ^_^;;;

Did you remember that you have to use a second switch to activate a common-event version?

Although, now that I think about it, it may have an error if you change maps, since it would have saved the bgm as it is in the map you lost your hp at instead of the map's... I think it'd be better to put in each map and change the bgm to the map's instead of saving and replaying the bgm.
Your call though.

I suppose I could live with the events being in every map... as long as I didn't have to have a SWITCH in every map.  I'ma try it on two different maps and see how it works. :)

As a common event it doesn't work.  I suppose I can live with that. It works like a charm with two different maps and BGMs. :D     I'm going to copy the event and see if it will work similarly with a guard chase, but that's another thread....

Obrigado, @Waterguy!

Mods, feel free to close this.... unless I'm missing somethin'.

Guys I found a simpler way to do this that I'm using in my game, and it requires no advanced scripting.

Step 1: Go to database.

Step 2: Go to the troops page.

Step 3: Select the troop you want to modify

Step 4: On the troop event page, make a If x actor's health is x % for the tab.

Step 5: In the command block put a Change Battle BGM command and for added effect put a tint screen command. For best effect, make the BGM more tense/danger sounding.

Step 6: Create a new event page, this time make it a If x enemy's health is x % for this tab.

Step 7: Make a Change Battle BGM command and have the battle BGM sounding more victorious.

Step 8: Rinse and Repeat steps 4 - 7 for each troop and each enemy in each troop. 

Note: do NOT edit the enemy itself, just edit the troops page!

Note 2: This works for making the Battle BGM change depending on health percent, but I haven't figured out a way to make it revert back to normal if the player is healed.

I see.  Does this work OUTSIDE OF BATTLE too, since that's the main function of this whole thing... and since there's actually no battle system in my game.

Stick an autorun event (or a parallel process if you already have an autorun) somewhere on the map where the player won't get to.

Conditional Branch: If Actor X's Health = 25% or less

Tint Screen

Else

Blank

It should work, you would also have to add a fix to see if the player's health is above x percent and just have it doing nothing.

I'm still quite new to RPG Maker myself, but I've packed 109 hours into it and gotten about 30 minutes of my game done. 

There is no such Conditional Branch outside battle event pages. Or  at least I can't find it, please show me if I am wrong.
Also, how does Tint Screen affect sound?

Thanks for the alternate ideas, but I'm going to use waterguy's way.  It DOES work outside of battle. :) The tint screen works LIKE A CHARM. <3  If you go to another area where there's different music, it will break...  No way around that. I tried.  HOWEVER, if you leave the map to another map where BGM does not change, the music stays the same. If you go back to that original map where the BGM was saved, it will revert back but the screen will still be tinted.  Upon healing, the screen goes normal and the process repeats again should HP fall below 2.  :)

Man this looks really cool! I cant wait to play it!
