Properties set various values regarding the behavior of a DECORATE actor. If a propert has the same name as a ZDoom property the behavior should be assumed to be similar.

Actor Properties


  • Damage value
Specifies the amount of damage the actor will do on impact. If the damage is given in parenthesis the value will be absolute. Otherwise, it will use the value*random(1,8).
  • GibHealth value
The negative health threashold before the actor enters its extreme death state.
  • Health value[, skill2 ...]
Sets the number of hit points the actor has. If multiple health values are given the health will apply to the next successive skill level. Unspecified skills will use the next highest value. (In other words, if only skills 1 and 2 are given skill 3 will use the value for skill2.)
  • PainChance value
The chance (out of 256, where 256 = Always) the actor will enter the pain state when damaged.
  • SightTime value[, random]
The number of function calls (usually A_Look) it takes for the actor to react to seeing the player. The random portion is the maximum number of tics to add to the base value.
  • Speed value[, runspeed]
The amount the actor moves in one Doom tic or one call to A_Chase. The speed will be changed to runspeed when the actor sees the player.


  • Height value
The height of the actor. This is ignored at the time, but should be set to 64 for all solid actors for forwards compatibility.
  • Radius value'
The radius of the actor.


  • MinMissileChance value (New from 1.3)
Gives the minimum chance (0-256) the monster has of not attacking when attempting to attack. Lower values are more aggressive.
  • MissileFrequency value (New from 1.3)
Gives a floating point multiplier for the missile chance curve. Higher values will make the monster attack more frequently over longer distances.


  • ActiveSound soundname
Defines the sound to randomly play while the actor is active.
  • AttackSound soundname
Defines the sound to play when the actor attacks.
  • DeathSound soundname
Defines the sound to play when A_Scream is called.
  • PainSound soundname
Defines the sound to play when A_Pain is called.
  • SecretDeathSound soundname
Defines the alternative deathsound to play when the level requests it.
  • SeeSound soundname
Defines the sound to play when the actor sees the player.


Defines scaling factors for the actor's sprite. Scale sets both xscale and yscale.


  • DropItem classname[, probability[, amount]]
When an actor dies it will drop items based off this property. A probability can be specified (0-255) which indicates the liklihood of the item spawning. Amount is used for ammunition and indicates how much ammo the pickup should give.
  • Points score
Number of points to give to the target when the actor is killed or picked up.

  • Normal is the default value and corresponds to the bobbing motion used in all old Doom-engine games.
