The following flags will modify the behavior of DECORATE actors in certain ways. If the flag name matches one in ZDoom it is generally safe to assume that the behavior will be similar to that flag in ZDoom.

General Flags

Physics

• SHOOTABLE

The actor can be damaged by attacks.

• SOLID

The actor is solid and should block other actors from moving through it.

Behavior

• AMBUSH

The actor does not respond to sounds and instead waits for the player to come in line of sight.

• DROPBASEDONTARGET

Instead of dropping every item in the dropitem list, drop one item based on if the item is present in the target's inventory.

• OLDRANDOMCHASE

Modifies A_Chase to use the old random number generator table. This flag was added since the number of times a typical Wolfenstein monster calls A_Chase will frequently cycle through the 256-entry random table causing a noticeable difference in aggressiveness at long distances. In general it is preferable to use the new random number generator.

(In)Abilities

• CANUSEWALLS

The monster can active doors. Unlike ZDoom, monsters can open locked doors by default.

• REQUIREKEYS

The monster needs to have keys in their inventory to open a locked door.

Apperance

• BRIGHT

Treats all states as having the bright flag set.

• RANDOMIZE

For monsters this will randomize the first frame to any duration up to what is specified. For projectiles this randomizes the death frame as well with both randomizations cutting up to 3 tics.

Projectile

• MISSILE

The actor is a projectile. The actor will move based on its speed automatically, die on collision, etc.

Miscellaneous

• ALWAYSFAST

A monster with this flag will always attempt to attack when A_Chase is called instead of taking a random number of steps.

The actor is tallied for treasure.

• COUNTKILL

The actor counts as a kill.
