Units can be created from some buildings and can be used to construct, collect resource or attack other factions.
To create a unit, create a new empty object which will be the parent object of the unit. Set the layer of this object to “Unit”. Then drag and drop the unit’s model as a child object of the unit parent object. All the unit’s model objects must have “Unit” as a layer. Make sure that when the unit’s parent object is placed at the same Y-Axis as the terrain, the unit’s model is completely over the terrain and is totally visible.
