(Question) Adding arbitrary units/models to an already loaded map

If I want to render, say a sphere, into an already loaded + rendered wc3 map, what would be the most appropriate way to go about this?

Looking at the code in mdx-m3-viewer\src\viewer\handlers\w3x\viewer.ts lines 627-656:

for (let unit of unitsDoo.units) {
      let row: MappedDataRow | undefined;
      let path;

      // Hardcoded?
      if (unit.id === 'sloc') {
        path = 'Objects\\StartLocation\\StartLocation.mdx';
      } else {
        row = this.unitsData.getRow(unit.id);

        path = <string>row.file;

        if (path.endsWith('.mdl')) {
          path = path.slice(0, -4);
        }

        path += '.mdx';
      }

      if (path) {
        this.load(path)
          .then((model) => {
            if (model) {
              this.units.push(new Unit(this, <MdxModel>model, row, unit));
            }
          });
      } else {
        console.log('Unknown unit ID', unit.id, unit);
      }
    }

It looks like I can just add units/objects to the map like so -

    if (model) {
        this.units.push(new Unit(this, <MdxModel>model, row, unit));
    }

given that I provide -

• a model class
• stub object for unit that holds info such as scale, location, angle, player, etc.
• stub object for row
• a model instance class that implements the setScene method

My understanding is that the model should be able to create a model instance and is in charge of determining what webgl program to use to render itself. I would start off by using an existing primitive such as a sphere.

I recommend reading this tutorial and other relevant pages on that site, it has been very useful to me in the past.

Also I just realized that uses heightMap, from the time the height values were saved on the client. But you can look at groundNormal() just above it 😂
