Set Doodad State is a trigger action in StarCraft. It was originally intended for use with doodad units. When used on other units (via the use of a third-party map editor), it can cause a number of strange effects, though the two most common are the cloaking of non-cloakable units and game crashes.

Background

Some doodads on the Installation tileset have unit sprites attached to them; these unit sprites function quite similarly to ordinary units. The units include doors and "trap" units that attack when hostiles approach. Set Doodad State was designed to allow mappers to manipulate and script the behaviors of these units.

Set Doodad State lets a mapper enable or disable a unit. When door units are enabled, they close; disabling them causes them to open, and let other units pass. Trap units engage and enter their attack states when enabled; disabling them causes them to withdraw.

When used on non-doodad units, however, the trigger action essentially causes the execution of non-existent game scripts. Essentially, this is an example of undefined behavior.

Effects by unit

The following units labeled "cloaks" will almost always cloak when disabled, though some may experience other quirks.

Note that buildings must be detected or otherwise seen by a player before cloaking (and then they only appear cloaked to that player and anyone that shares vision of them). Protoss buildings must also either be powered by a Protoss Pylon or enabled (before being disabled). Terran add-ons must be attached to their host building to cloak. All cloaked buildings will be visible in the light fog of war that covers areas that a player has explored but doesn't have vision of.

Certain overlays (such as on beacons, powered shield batteries, or building fire) will still be visible when the unit is cloaked. This is useful for creating certain effects like burning trees or lights.

Some units cannot be placed on a map for various reasons (or do not appear during gameplay), and hence cannot be tested. These units are marked as "Unknown/unused".

Disabled powerups can not be picked up.
