Bug encounter on battle with Yanfly and Olivia plugin

[Grumphlu]

Hi Everyone,

I am using Yanfly plugins and Olivia plugins and during a boss battle i use some "Force-Actions" when life drop at 50% then 25%.
Sometimes the game enter in conflict and sometimes not. I have no clue to know what make this happen.

I took a screenshot if someone understand it better than me he will be my savior,

Thanks in advance

I think this generally means the JSON can't be parsed, which indicates you have something wrong with your notes somewhere.

Can you narrow it down to a particular force action or a particular skill or weapon or something? If not, you'll have to start checking every slot in every database tab, to see if you can find one that's not correct.

My force actions are all particular skills casted by my boss.

This error generaly happen in the end of a turn. Do you think this is a problem with my skill notetag ?

Look like there is a problem with the position of my ennemies maybe (i am realy not good with plugin and general coding...)

As the error is in JSON.parse, I think it's SOMETHING wrong with whatever it's trying to make a copy of. Could be a skill, could be an actor or enemy, don't know without looking at the plugin. I would first look at your notes, but it could also be some weird characters in a description or name somewhere.

Can you get a screenshot of the console when you get the error (play, get the error, hit F8 to open developer tools, click on Console tab). That might have more information.

Ok i will try to get the error, it might take some time, i will have to run many fights ^^

(Also thanks you so much for helping me )

This may be the same problem as discussed here:

Need help with an error please.

Hey there gang. I have been getting a seemingly random crash in battle. I understand most of the error code but it references a .json.parse () and that is throwing me off I was hoping some could help me with this one. My MV is version 1.6.2. I'll post an image of the error below. Big thanks for...

Previously when I've encountered this "JSON.parse token u at position 0" error, it has meant that something tried to JSON.parse(undefined). Given that line 2015 of Yanfly's Battle Engine Core seems to be this:

      action: JsonEx.makeDeepCopy(this._action),

...I would suspect that the error is due to BattleManager._action being undefined. This is possible if the battler in question is immobilised, since in that case their action queue will be empty and the first action undefined.

There could be other reasons for an empty action queue, e.g. if they've already completed their action phase this turn. Since this "remember previous action" thing is introduced by Yanfly's Battle Engine Core, I think the most effective solution would be to patch that plugin somehow. It would be best to try to reliably reproduce the problem first, though: that way you can be much more certain that any fix you find actually does (or doesn't) work.

I came up with something that might solve the problem (just theory, I haven't tested it). Save the following code as a .js file (Save As > File Type: All Files, Filename: whateverYouLike.js), import as a plugin, and make sure to load it immediately after Battle Engine Core in the Plugin Manager~

Spoiler: A fix?

// Place immediately below YEP_BattleEngineCore in the Plugin Manager

// Override - "no action" failsafe to avoid JSON.parse failure
BattleManager.setPreForceActionSettings = function() {
  return {
    subject: this._subject,
    action: this._action ? JsonEx.makeDeepCopy(this._action) : undefined,  // <- edit 1 of 1
    actionList: JsonEx.makeDeepCopy(this._actionList),
    targets: this._targets.slice(),
    allTargets: this._allTargets.slice(),
    indTargets: this._individualTargets.slice(),
    phaseSteps: JsonEx.makeDeepCopy(this._phaseSteps),
    returnPhase: this._returnPhase,
    phase: this._phase,
    conditionFlags: JsonEx.makeDeepCopy(this._conditionFlags),
    trueFlags: JsonEx.makeDeepCopy(this._trueFlags)
  }
};

// Override - do not restore "no action"
BattleManager.loadPreForceActionSettings = function() {
    var settings = this._forceActionQueue[0];
    if (settings) {
      this._forceActionQueue.shift();
      if (!settings.action) return false;  // <- edit 1 of 1
      this.resetPreForceActionSettings(settings);
      return this._subject && this._subject.isAppeared();
    } else {
      return false;
    }    
};
