Generic Keyvalues, Inputs and Outputs/Keyvalues

Keyvalues

Name (targetname) <string>

The name that other entities use to refer to this entity.

Class (classname) <string>

Determines the characteristics of the entity before it spawns.

Tip:Changing this on runtime still has uses, but should be used sparingly, as certain entities expect entities to have certain classnames. For example, using a classname defined in S_PreserveEnts will persist the entity on new rounds.

Global Entity Name (globalname) <string>

When entity transitions to different map which has an entity with same globalname (and classname) properties of this entity (color, origin, angles etc.) will be copied over to that entity. (unless the given property is marked not to transfer e.g. model)

Important:Meant to be used in singleplayer games which have style map transition ( is not one of those)

Model (model) <string>

In-game representation of the entity to display. For brush entities, this is a reference to a non-zero bmodel index in the current BSP. For point entities, this is the path to an MDL model or VMT sprite, relative to the game's root directory. Not all entities will actually render the model, and only specific entities will precache the model defined here (non-precached models cannot be displayed).

Origin (X Y Z) (origin) <coordinates>

The position of this entity's center in the world. Rotating entities typically rotate around their origin.

Bug:Editing this manually in Hammer does not move point entities accordingly in the editor.

Note:Brush entities with this keyvalue count towards leak tests, whereas they do not if this keyvalue is absent.

Pitch Yaw Roll (Y Z X) (angles) <angle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Note:This works on brush entities, although Hammer doesn't show the new angles.

Flags (spawnflags) <flags>

Toggles exclusive features of an entity, its specific number is determined by the combination of flags added. In hammer it has its own tab in entity properties called 'Flags'

Damage Filter (damagefilter) <targetname>

Name of a filter that controls which entities can damage this entity.

Parenting

Parent (parentname) <targetname>

Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (parentname [targetname],[attachment])

Tip:Entities transition to the next map with their parents (not in )

Tip:phys_constraint can be used as a workaround if parenting fails.

Vscript

Entity Scripts (vscripts) <scriptlist> (in all games since ) (also in )

Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions. Scripts executed on the worldspawn entity will be placed in root scope.

Think function (thinkfunction) <string> (in all games since ) (also in )

Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Must be present when entity is spawning, setting it later (for example via AddOutput) has no effect. Avoid expensive operations in this function, as it may cause performance problems.

Rendering

RenderFields:

Render Mode (rendermode) <byte choices>

Set a non-standard rendering mode on this entity.

Render Modes

0: Normal 1: Color 2: Texture 3: Glow 4: Solid/Alphatest 5: Additive 6: Removed, does nothing 7: Additive Fractional Frame 8: Alpha Add 9: World Space Glow 10: Don't Render

Render FX (renderfx) <byte choices>

Various somewhat legacy alpha effects. See render effects.

Render Amount / Transparency (renderamt) <byte>

Transparency amount, requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.

Render Color (R G B) (rendercolor) <color255>

Color tint.

Shadow:

Disable Shadows (disableshadows) <boolean>

Prevents the entity from creating cheap render-to-texture shadows, or lightmap shadows if the entity is a prop_static. Does not affect shadow mapping.

Disable Receiving Shadows (disablereceiveshadows) <boolean>

Prevent the entity from receiving dynamic shadows on itself.

Shadow Cast Distance (shadowcastdist) <integer> !FGD

Sets how far the entity casts dynamic shadows. 0 means default distance from the shadow_control entity.

Disable Shadow Depth (disableshadowdepth) <boolean> (in all games since )

Used to disable rendering into shadow depth (for projected textures) for this entity.

Disable flashlight (disableflashlight) <boolean> (in all games since )

Used to disable projected texture lighting and shadows on this entity.

Projected Texture Cache (shadowdepthnocache) <integer choices> (in all games since )

Used to hint projected texture system whether it is sufficient to cache shadow volume of this entity or to force render it every frame instead.

Choices

0 : Default 1 : No cache - render every frame 2 : Cache it - render only once

Miscellaneous

Effects (effects) <flags> !FGD Combination of effect flags to use. Lag Compensation (LagCompensate) <boolean> (in all games since ) !FGD Set to Yes to lag compensate this entity. Should be used very sparingly! Is Automatic-Aim Target (is_autoaim_target) <boolean> (in all games since ) !FGD If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.
