 /*:
 * @target MZ
 * @plugindesc v1.01 Show Text on your screen.
 * <ScreenVariablesMZ>
 * @author Krimer
 *
 * @param Variable Number
 * @desc Number of variable where your text data saved
 * @default 0
 *
 * @param Auto-Refresh
 * @desc Text auto-refresh. true or false
 * @default false
 *
 * @help
 *
 * Available script calls:
 * 'Key' - Is text identifier, provide access to each text separately.
 * 'visibility' - text visibility, On(true)\Off(false)
 * this.addVarHudText('Key','your text',Х,Y,visibility) - add text to your screen.
 * Example: this.addVarHudText('test','Text Check',66,66,true)
 *
 * this.textVarTurnOn('Key') - Change text visibility on true, using text key
 * this.textVarTurnOff('Key') - Change text visibility on false, using text key
 * this.textVarSetXY('Key',Х,Y) - Change Х & Y for text using text key.
 * this.textVarGetX('Key') - Get current Х of the text using text key.
 * this.textVarGetY('Key') - Get current Y of the text using text key.
 * this.changeVarText('Key', 'your text') - Change text using text key.
 * this.showAllVarText() - Change all texts visibility on true
 * this.hideAllVarText() - Change all texts visibility on false
 * this.showVarWindow() - Show all texts, doesn't change visibility setting on text.
 * this.hideVarWindow() - Hide all texts, doesn't change visibility setting on text.
 * this.deleteVar() - Delete text using text key.
 * this.varHudRefresh() - Manual refresh for all texts.
 *
 * =============================================================================
 * Text support some standard special characters:
 * \\V[n] - Will be replaced with the value of the nth variable.
 * \\N[n] - Will be replaced with the name of the nth actor.
 * \\P[n] - Will be replaced by the name of the nth (arranged order) party member.
 * \\G - Will be replaced by the currency unit.
 * \\C[n] - Draw the subsequent text in the nth color.
 * \\I[n] - Draws the nth icon.
 * \\{ - Increases the text by 1 step.
 * \\} - Decreases the text by 1 step.
 * Double slash is necessary
