GetActorProperty

int GetActorProperty (int tid, int property)

Parameters

• tid: TID of the actor. Use 0 to refer to the activator.

• property: One of the properties listed below.

Actor Properties

APROP_Accuracy	integer	Accuracy of the actor.
APROP_Alpha	fixed point	Alpha of the actor. Range is [0.0, 1.0]
APROP_Ambush	bool	Whether the actor's AMBUSH flag is set or not.
APROP_AttackZOffset	fixed point	The attack z offset of the player.
APROP_ChaseGoal	bool	Walks to goal instead of target if a valid goal is set
APROP_Damage	integer	Actor's damage.
APROP_DamageFactor	fixed point	Generic damage factor for the actor. It is applied before any specific DamageFactor.
APROP_DamageMultiplier	fixed point	Generic damage multiplier for the actor. This is typically used on actors (e.g monsters) to strengthen or weaken the damage they deal from their attacks.
APROP_DamageType	string	Actor's damage type.
APROP_Dormant	bool	Whether or not actor has the DORMANT flag.
APROP_Dropped	bool	Whether or not actor has the DROPPED flag. Dropped items are destroyed by closing doors and crushers while non-dropped items are not; and in games with the “Weapons Stay” option of DMFlags turned on, only weapons with the DROPPED flag set to 0 stay. By default, any item not placed originally on the map has the DROPPED flag set to 1.
APROP_Friction	fixed point	Actor's current friction factor.
APROP_Friendly	bool	Actor is friendly to the player and hostile to enemies. In addition to setting and clearing the FRIENDLY flag, when the property is set to true, the total kill count of the map is decreased by one for each affected actor, provided they are countable (only hostile monsters are countable), and is increased when the property is set to false.
APROP_FriendlySeeBlocks	integer	The range in which friendly monsters or hostile monsters with SEEFRIENDLYMONSTERS on can see other non-player actors. This value is measured in increments of 128 map units, e.g a value of 32 equals a range of 4096 map units.
APROP_Frightened	bool	Monster runs away from player.
APROP_Gravity	fixed point	Current gravity factor of actor.
APROP_Health	integer	Actor's current health. Setting this property to 0 or less, kills the actor.
APROP_Height	fixed point	Actor's current height.
APROP_Invulnerable	bool	Actor will not lose any health.
APROP_JumpZ	fixed point	Player's jump height. The formula for jumping distance is (JumpZ * 2) / 2 + MaxStepHeight, and to get a specific JumpZ from a jumping height you want to achieve, use Sqrt((jump height - MaxStepHeight) / 2 ) * 2.
APROP_Mass	integer	Actor's mass.
APROP_MasterTID	integer	The TID of the actor linked to by the actor's master field.
APROP_MaxDropOffHeight	fixed point	Defines the maximum height of a step this actor can climb down when moving.
APROP_MaxStepHeight	fixed point	Defines the maximum height of a step this actor can climb up when moving.
APROP_MeleeRange	fixed point	Actor's melee range.
APROP_NoTrigger	bool	Whether or not actor has the NOTRIGGER flag.
APROP_NoTarget	bool	Actor cannot be targeted by other monsters.
APROP_Radius	fixed point	Actor's current radius.
APROP_ReactionTime	integer	The time in tics a monster needs to attack back. However, the main use of this property is to serve as a counter for A_Countdown.
APROP_RenderStyle	integer	How the actor is rendered: STYLE_None Do not draw STYLE_Normal Normal; just copy the image to the screen STYLE_Fuzzy Draw silhouette using “fuzz” effect STYLE_SoulTrans Draw translucent with amount in transsouls CVAR STYLE_OptFuzzy Draw as fuzzy or translucent, based on user preference STYLE_Stencil Draw as single color STYLE_AddStencil Draw as single additive color STYLE_AddShaded Treats 8-bit indexed images as an alpha map while applying additive translucency. Index 0 = fully transparent, index 255 = fully opaque. STYLE_Translucent Draw translucent STYLE_Add Draw additive STYLE_Shaded Treats 8-bit indexed images as an alpha map. Index 0 = fully transparent, index 255 = fully opaque. STYLE_TranslucentStencil Draw as single translucent color STYLE_Shadow Draw dark translucent stencil STYLE_Subtract Draw subtractive
APROP_ScaleX	fixed point	Horizontal scaling of the actor's sprite. Does not affect collision box size.
APROP_ScaleY	fixed point	Vertical scaling of the actor's sprite. Does not affect collision box size.
APROP_Score	integer	A simple counter. Score items automatically increase it by their amount.
APROP_SpawnHealth	integer	The current max health of the actor. Only players may have their max health set this way. Note that for them the default value is 0, which is interpreted as "100 unless modified by DeHackEd". The Player.MaxHealth property can change the default value.
APROP_Speed	fixed point	Actor's speed. For monsters, this is the distance they move every time A_Chase is called. For projectiles, this is the distance they move each tic. For players, this is multiplied by the player's class speed to determine the final speed the player will move for each tic that they have a movement key held down. Consequently, the standard APROP_Speed for a player is always 1.0, not what their actual speed is.
APROP_Stamina	integer	Stamina of the actor.
APROP_StencilColor	color	Stencil color of the actor, as a hexadecimal value, e.g. 0xFFFFFF (white).
APROP_TargetTID	integer	The TID of the actor linked to by the actor's target field.
APROP_TracerTID	integer	The TID of the actor linked to by the actor's tracer field.
APROP_ViewHeight	fixed point	The view height of the player.
APROP_Waterlevel	integer	How "submerged" the actor is. 0: Not submerged at all (e.g. standing on solid ground) 1: Less than half submerged ("ankle deep") 2: At least half submerged ("waist deep") 3: Entirely submerged (completely underwater)
APROP_WaterDepth	fixed	(New from 4.11.0) The exact depth at which the actor is submerged at in a water volume.

Return value

The value of the specified property of the actor. Since ACS does not handle dynamic strings (this is not the case starting with ^r4295), this function cannot be used with certain properties and CheckActorProperty can be used instead (note that as of ^r4307, this is not the case, and this function can be used on string-based properties). It's important to note that when using APROP_Health, it returns the exact value of the current health, even if it's a negative value.

Examples

This script checks for a few different properties and prints helpful messages about them.

script 1 (int tid)
{
    if (GetActorProperty (tid, APROP_HEALTH) <= 25)
        print (s:"Thing ", d:tid, " has less than 26 health!!");

    if (GetActorProperty (12, APROP_RENDERSTYLE) == STYLE_OPTFUZZY)
        print (s:"Thing 12 is probably a spectre!");
}
