item_nugget
item_nugget
is a point entity available in Portal 2. It is an "Aperture Incentivizing Nugget", seemingly intended as a collectible item for a scrapped multiplayer mode. Touching the nugget will pick it up, adding to the player's "score", which can be seen only in multiplayer by binding a key to
+score
and using it to open the scoreboard. Once picked up, the nugget will respawn after a configurable amount of time.
The model used by the entity is a modified version of the Team Fortress 2 neutral capture point hologram, with the beam removed and various colored skins added with the Aperture logo and the point value in the center. In-game, the model is also scaled based on the point value, with 25 points being the largest.
Keyvalues
- Group Name
(groupname)
<string> - "Giving nuggets a group name hints the game that they are intended to be a group." Unknown use.
- Respawn Time
(RespawnTime)
<float> - Number of seconds between when the nugget is collected and when it respawns
- Point Value
(PointValue)
<integer> - Amount of points the nugget gives when collected. Accepts only the following values, others will cause it to be reduced to the nearest allowed value:
- 1
- 5
- 10
- 25
BaseAnimating:
- Skin
(skin or ModelSkin
<integer>)
- Some models have multiple skins. This value selects from the index, starting with 0.
- Collisions
(solid)
<choices> - Method of collision for this entity.
- Body Group
(body or SetBodyGroup)
<integer> !FGD - Sets the the active
$bodygroup
.
- Model Index
(modelindex)
<short> !FGD - Given the number index from dumping the
cl_precacheinfo modelprecache
table, sets entity model to the index.Warning:If an entity has animations that will be played, then the set model also must have its own sequences, else the game crashes.
- Model Scale
(modelscale)
<float> (in all games since) (not in
) !FGD
- A multiplier for the size of the model. Negative values are accepted. Does not alter the physics collisions in most cases, however.
Warning:Negative or extremely high values can cause crashes!
Animating
- Sequence
(sequence)
<integer> !FGD - Default animation sequence for the model to be playing after spawning.
- Playback Rate
(playbackrate)
<float> !FGD - A multiplier of the framerate at which animations are played, negative values are accepted. Default is 1.0.
- Texture Frame
(texframeindex)
<integer> !FGD - The initial frame number for all animated textures on this entity.
Effects - Render
- Start Fade Distance
(fademindist)
<float> - Distance at which the entity starts fading. If 0 or less, the entity will disappear instantly when end fade is hit. The value will scale appropriately if the entity is in a 3D Skybox.
- End Fade Distance
(fademaxdist)
<float> - Distance at which the entity ends fading. If 0 or less, the entity won't disappear at all. The value will scale appropriately if the entity is in a 3D Skybox.
- Fade Scale
(fadescale)
<float> - If specified in the
worldspawn
, or if the engine is running below DirectX 8, entities will fade out even if the fade distances above aren't specified. This value gives more control over when this happens: numbers smaller than 1 cause the entity to fade out at further distances, and greater than 1 cause it to fade out at closer distances. Using 0 turns off the forced fade altogether. See also$noforcedfade
.
- FX Amount/Transparency (0–255)
(renderamt)
<integer> - Transparency amount, requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.

Base:
- 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

phys_constraint
can be used as a workaround if parenting fails.
- Origin (X Y Z)
(origin)
<coordinates> - The position of this entity's center in the world. Rotating entities typically rotate around their origin.
Note: Hammer does not move the entities accordingly only in the editor.
- Pitch Yaw Roll (X Y Z)
(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.
- Classname
(classname)
<string> !FGD - Determines the characteristics of the entity before it spawns.
Tip: Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!
- Flags
(spawnflags)
<integer> !FGD - Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Entity Scripts
(vscripts)
<scriptlist> (in all games since)
- 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.
- Think function
(thinkfunction)
<string> (in all games since)
- 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. Avoid expensive operations in this function, as it may cause performance problems.
- Lag Compensation
(LagCompensate)
<boolean> (in all games since) !FGD
- Set to Yes to lag compensate this entity. Should be used very sparingly!

Base:
AddContext
<string>- Adds to the entity's list of response contexts. Format is
<key>:<value>
.
AddOutput
<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.

FireUser1
toFireUser4
- Fires the respective
OnUser
outputs; see User Inputs and Outputs.
Kill
- Removes this entity and any entities parented to it from the world.

<string>- Remove a context from this entity's list. The name should match the key of an existing context.
SetParent
<string>- Move with this entity. See Entity Hierarchy (parenting).

RunScriptCode
<string> (in all games since) (also in
)
- Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.
Bug:In Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.

or theIgnite
inputs. OnFizzled
(only in)
- Fired when this entity is fizzled by a
trigger_portal_cleanser
or, forprop_weighted_cube
, the Dissolve or SilentDissolve inputs.Bug:It does not fire when the object is fizzled by other means such as
env_entity_dissolver
.
Base:

FireUser1
toFireUser4
Input; see User Inputs and Outputs.
