Understanding Mapgen Basics

Mapgen, short for Map Generator, is a feature in Supreme Commander that allows players to create their own custom maps. It is a powerful tool that can be used to create a wide variety of maps, from small skirmish maps to large-scale strategic maps.

Mapgen is divided into two main modes: default mode and advanced mode. Default mode is the most beginner-friendly mode, and it provides a simple interface that makes it easy to get started with map making. Advanced mode, on the other hand, provides more advanced features and options, giving players more control over the map creation process.

To create a new map in Mapgen, players first need to select a map template. Map templates define the basic parameters of the map, such as the size, shape, and terrain type. Once a map template has been selected, players can begin to add objects to the map, such as units, buildings, and resources.

Objects can be added to the map in two ways: by placing them manually or by using the object brush tool. The object brush tool allows players to quickly and easily add multiple objects to the map by painting them on the terrain.

Once players have added all of the objects to the map, they can then save the map and export it to Supreme Commander. Exported maps can be played in both single-player and multiplayer modes.

Here is a table summarizing the key features of Mapgen:

Feature	Description
