Oh, boy! Here we go again...


Okay, for some reason when it reaches to the point of the low hp (and only that point), the game crashes with error "TypeError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': float parameter 1 is non-finite."


Here's the code:


var FirehawkADK = FirehawkADK || {};
FirehawkADK.HPControl = FirehawkADK.HPControl || {};
// Reference the Plugin Manager's parameters.
var paramdeck = PluginManager.parameters('HPColor');
//Load variables set in the Plugin Manager.
FirehawkADK.HPControl.CompatMode = String(paramdeck['Compatibility Mode']).trim().toLowerCase() === 'true';
FirehawkADK.HPControl.LowHPLimit = parseFloat(paramdeck['Low HP']);
FirehawkADK.HPControl.CriticalHPLimit = parseFloat(paramdeck['Critical HP']);
FirehawkADK.HPControl.HPNormalBar1 = Number(paramdeck['Normal HP Color 1']);
FirehawkADK.HPControl.HPNormalBar2 = Number(paramdeck['Normal HP Color 2']);
FirehawkADK.HPControl.HPLowText = Number(paramdeck['Low HP Text']);
FirehawkADK.HPControl.HPBarLow1 = Number(paramdeck['Low HP Bar Color 1']);
FirehawkADK.HPControl.HPBarLow2 = Number (paramdeck['Low HP Bar Color 2']);
FirehawkADK.HPControl.CriticalHPText = Number(paramdeck['Critical HP Text']);
FirehawkADK.HPControl.CriticalHPBar1 = Number(paramdeck['Critical HP Bar Color 1']);
FirehawkADK.HPControl.CriticalHPBar2 = Number(paramdeck['Critical HP Bar Color 2']);

else return this.systemColor();
};

Window_Base.prototype.hpbarColorPicker1 = function(actor) {
if (actor.hp < actor.mhp * FirehawkADK.HPControl.CriticalHPLimit) return this.textColor(FirehawkADK.HPControl.CriticalHPBar1);
else if (actor.hp > actor.mhp * FirehawkADK.HPControl.CriticalHPLimit && actor.hp < actor.mhp * FirehawkADK.HPControl.LowHPLimit) return this.textColor(FirehawkADK.HPControl.HPBarLow1);
else if (FirehawkADK.HPControl.CompatMode == true) this.hpGaugeColor1();
else return this.textColor(FirehawkADK.HPControl.HPNormalBar1);
};

var color1 = this.hpbarColorPicker1(actor);
var color2 = this.hpbarColorPicker2(actor);
this.drawGauge(x, y, width, actor.hpRate(), color1, color2);
this.changeTextColor(this.hpTextColorPicker(actor));
this.drawText(TextManager.hpA, x, y, 44);
this.drawCurrentAndMax(actor.hp, actor.mhp, x, y, width,
this.hpColor(actor), this.normalColor());
};
