What are units, items, destructibles, and doodads?
They are all objects, they can all be modified with the object editor, and they can all be placed on the map with the terrain editor. Abilities, upgrades, buffs, and effects are objects too, even though they can’t be placed on the map. They will be covered in the abilities section of the FAQ. • Buildings, troops and heroes are units. You can do pretty much anything to a unit. They can have abilities, upgrades, and attacks. • Trees and bridges are destructibles. You they can be created or destroyed during the map, but they can’t be moved. Some special purpose doodas have other functions as well. • Bushes, flowers, and rocks are doodads. They cannot be changed in any way during the game. • Items can be created, destroyed, picked up, and used. They can have abilities, but they only apply while in a hero’s inventory.
