I just realized i posted the wrong code, my mistake, here is what i tried:

import { RPM } from "../path.js";
import { Graphic } from "../core/index.js";

const pluginName = "ShowText";
const inject = RPM.Manager.Plugins.inject;

class MyTextPlugin {
  constructor() {
    this.textGraphic = new Graphic.Text("mytext", {
      x: 0,
      y: 0,
      w: 0,
      h: 0,
      align: Align.Left,
      fontSize: Utils.defaultValue(
        Datas.Systems.dbOptions.v_tSize,
        Constants.DEFAULT_FONT_SIZE
      ),
      fontName: Utils.defaultValue(
        Datas.Systems.dbOptions.v_tFont,
        Constants.DEFAULT_FONT_NAME
      ),
      verticalAlign: AlignVertical.Center,
      color: Utils.defaultValue(
        Datas.Systems.dbOptions.v_tcText,
        System.Color.WHITE
      ),
      bold: false,
      italic: false,
      backColor: Utils.defaultValue(
        Datas.Systems.dbOptions.v_tcBackground,
        null
      ),
      strokeColor: Utils.defaultValue(
        Datas.Systems.dbOptions.tOutline,
        false
      )
        ? Utils.defaultValue(Datas.Systems.dbOptions.v_tcOutline, null)
        : null,
    });
  }

  drawText() {
    this.textGraphic.draw();
  }
}

const myTextPluginInstance = new MyTextPlugin();

inject(Scene.Map.prototype, "drawHUD", function () {
  this._super.drawHUD.call(this);
  myTextPluginInstance.drawText();
});

Yes, you need to add RPM module before each module that come from RPG Paper Maker (or import each needed modules if you don't want to use RPM everytime). For example, use new RPM.Graphic.Text(...) for your error at line 8.

I think im just going to put the brakes on this for now haha 🤣 learning a whole new programming language takes some time so i'll just wait haha.

@wano So im just trying to draw a simple window box, but i still get those errors. I included all the neccessary imports

import { RPM } from "../path.js"
import { Graphic } from "../../System/index.js";

const pluginName = "ShowText";
const inject = RPM.Manager.Plugins.inject;

// Start code here

this.exampleWindow = new RPM.Core.WindowBox(0, 0, 25, 15, 
{ 
    // The following options are optional
    content: new Graphic.Text("myText"), // The content is a Graphic.Base
    padding: [0, 0, 0, 0], // [x, y, x, h] for box padding
    limitContent: true // If checked, the content will be cut according to padding
});

drawHUD() 
{
    this.exampleWindow.draw();
}
