<Left 4 Dead><Left 4 Dead 2> prop_minigun is a point entity available in the Left 4 Dead series. It is an usable mounted minigun that is normally used in the rescue point finale to support the survivors.

Flags

DynamicProp:

  • 64: Use Hitboxes for Renderbox
  • 256: Start with collision disabled

BreakableProp:

  • 16: Break on Touch
  • 32: Break on Pressure

Keyvalues

Max yaw <float>
Max yaw the gun can be turned.
Max pitch <float>
Max pitch the gun can be depressed.
Min pitch <float>
Min pitch the gun can be raised.

EnableDisable:

Start Disabled (StartDisabled) <boolean>
Stay dormant until activated (probably with the Enable input).

DynamicProp:

Default Animation (DefaultAnim) <string>
The animation this prop will play when not doing a random or forced animation.
Randomly Animate (RandomAnimation) <boolean>
Makes the prop randomly select and play animations at intervals defined by the Min/Max Random Anim Time KVs. In between the random animations, it will revert to playing Default Animation.
Min Random Anim Time (MinAnimTime) <float>
Minimum time between random animations.
Max Random Anim Time (MaxAnimTime) <float>
Maximum time between random animations.
Update children (updatechildren) <boolean>
Confirm:A boolean set to true by default. When set to 0, any children attached to this entity as an attachment will not update. (seems like it would not have a practical use...)
Disable Bone Followers (DisableBoneFollowers) <boolean> (New with Source 2009)
Disables generation of phys_bone_followers for each convex piece the model has in its collision model. phys_bone_followers can quickly eat up the edict count, so this keyvalue can be very helpful in freeing resources. This will however make the collision model no longer function ([confirm] As in become non-solid?), and the model will not be able to ragdoll anymore.

GMODSandbox:

Allow Physics Gun (gmod_allowphysgun) <boolean> (Only in Garry's Mod)
If set, players cannot use Physics Gun on this entity.
Sandbox Tool Whitelist (gmod_allowtools) <string> (Only in Garry's Mod)
If set, only given tools can be used on this entity. You need to supply the tool class names, the names of the .lua files of those tools. This also includes the context menu properties!

BreakableProp:

Explosion Damage (ExplodeDamage) <float>
If non-zero, when this entity breaks it will create an explosion that causes the specified amount of damage. See also Explosion Radius.
Explodsion Radius (ExplodeRadius) <float>
If non-zero, when this entity breaks it will create an explosion with a radius of the specified amount. See also Explosion Damage.
Break Model Message (BreakModelMessage) <string>
"If set, will use this break model message instead of the normal break behavior."
Confirm:Is this new with Source SDK 2013...? It isn't in Alien Swarm or 2007 code but is in 2013. New with L4D?

Breakable (common):

Performance Mode (PerformanceMode) <choices>
Used to limit the amount of gibs produced when this entity breaks, for performance reasons.
  • 0: Normal
  • 1: No Gibs
  • 2: Full Gibs on All Platforms (Xbox 360, PS3, etc)
  • 3: Reduced gibs
Min Damage to Hurt (minhealthdmg) <integer>
If a single hit to the object doesn't do at least this much damage, the prop won't take any of the damage it attempted to give.
Pressure Delay (PressureDelay) <float>
Seconds to delay breaking from pressure. Allows creaking/groaning sounds to play.
Health (health) <integer>
How close to breaking the object is.
Maximum Health (max_health) <integer>
Health cannot exceed this amount.
Physics Impact Damage Scale (physdamagescale) <float>
Multiplier for damage amount when this entity is hit by a physics object. With a value of 0 the entity will take no damage from physics.
Breakable By (BreakableType) <choices> (New with Left 4 Dead)
<Left 4 Dead><Left 4 Dead 2> only. Who can break this?
  • 0: Everyone
  • 1: All Infected
  • 2: Only Tanks

Model:

World Model (model) <string>
The model this entity should appear as. 128-character limit.
Skin (skin or ModelSkin <Alien Swarm>) <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.
Hitbox Set (hitboxset) <string> !FGD
Sets the $hboxset to use.
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
Cycle (cycle) <float> !FGD
The current frame of the currently playing animation, on a range from 0-1.
Lighting Origin (LightingOrigin) <targetname>
Select an entity (not info_lighting!) from which to sample lighting instead of the entity's origin.
Lighting Origin Offset (LightingOriginHack) <targetname> !FGD
The info_lighting_relative from which to sample lighting instead of the entity's origin. Not in <Left 4 Dead><Left 4 Dead 2>.
Damage Filter Name (damagefilter) <targetname>
When this entity receives damage, it will filter by this entity.
Start Fade Distance (fademindist) <float>
Distance at which the entity starts fading. If <0, 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, 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.
Render Mode (rendermode) <choices>
Set a non-standard rendering mode on this entity.
Render FX / Transparency (0 - 255) (renderamt) <integer>
Transparency amount, requires a Render Mode other than Normal. 0 is invisible, 255 is fully visible.

Shadow Cast Distance (shadowcastdist) <integer>
Sets how far the entity casts dynamic shadows. 0 means default distance from the shadow_control entity.
Disable Shadows (disableshadows) <boolean>
Prevent the entity from creating cheap render-to-texture shadows. Does not affect shadow mapping.
Disable Receiving Shadows (disablereceiveshadows) <boolean>
Prevent the entity from receiving shadows on itself.
Model Index (modelindex) <short> !FGD
Changes the entity's model to a precached model on the map.
Warning: Using an invalid value will instantly crash the game, this includes 0 and 1.
Texture Frame (texframeindex) <integer>
The frame number for any animated textures on this entity.
Model Scale (modelscale) <float> (New with Half-Life 2: Episode Two / Source 2007) !FGD
A multiplier for the size of the model. Negative values are accepted. Does not alter the physics collisions in most cases, however. Not in [Portal], <Left 4 Dead>, <Left 4 Dead 2>, sdk 2013.
Warning: Negative or extremely high values can cause crashes!
Glow Backface Multiple (glowbackfacemult) <float> (New with Left 4 Dead 2) !FGD
If this object has a glow effect, multiply the effect by this much on the sides of the object that are facing away from the viewer.

Base:

Classname (classname) <string>
The classname defines the type of entity. Classnames can be changed using AddOutput, which will influence how the engine deals with the entity in certain circumstances.
Name (targetname) <string>
The name that other entities refer to this entity by.
Global Entity Name (globalname) <string>
Name by which this entity is linked to another entity in a different map. When the player transitions to a new map, entities in the new map with globalnames matching entities in the previous map will have the previous map's state copied over their state.
Parent (parentname) <targetname>
Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma. Every entity can be parented, even point entities. Entities which are parented will be forced to transition to the next map, such as from a trigger_transition. Some entities which aren't intended to be parented may not function correctly. phys_constraint can be used as a workaround to parenting.
Origin (X Y Z) (origin) <coordinates>
The position of this entity's center in the world. Rotating entities typically rotate around their origin.
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.
Flags (spawnflags) <integer>
Toggles features of an entity, its specific number is determined by the combination of flags added.
Response Contexts (ResponseContext) <string>
Pre-defined response system contexts for this entity. Format is key:value,key:value,.... Contexts may be filtered.
Effects (effects) <integer> !FGD
Combination of effect flags to use.
Local Time (ltime) <float> !FGD
The local time of the entity, independent of the global clock. Used mainly for physics calculations.
Next Think (nextthink) <float> !FGD
Amount of time before the entity thinks again.
Hammer ID (hammerid) <integer> !FGD
The entity's Hammer ID. Mainly used by plugins and debugging commands, such as ent_keyvalue. Can be manually assigned with the "hammerid" or "id" keyvalue. Entities spawned at run-time are not assigned any Hammer ID.
Disable for Xbox 360 (disableX360) <boolean> (New with Left 4 Dead 2) !FGD
If Yes, disables this entity on the Xbox 360 version of Source.
Entity Scripts (vscripts) <scriptlist> (New with Left 4 Dead 2)
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.
Script think function (thinkfunction) <string> (New with Left 4 Dead 2)
Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call. Try to avoid expensive operations in this function, as it may cause performance problems.
Lag Compensation (LagCompensate) <boolean> (New with Left 4 Dead 2) !FGD
Set to Yes to lag compensate this entity. Should be used very sparingly!

Takes two values separated by a space. The first is the target model scale. The second value is the number of seconds the change in scale will be spread over.
Tip:The modelscale keyvalue can be AddOutputed as a workaround for other games with this input missing.

Warning: Negative or extremely high values can cause crashes!

EnableDamageForces
Allows the entity to be pushed by damage done to it (usually force amount correlates with the damage done).
DisableDamageForces
Prevents the entity from being pushed by damage done to it.
EnableShadow
Allows the entity to draw a render target shadow.
DisableShadow
Prevents the entity from drawing a render target shadow.

Base:

Kill
Removes this entity and any entities parented to it from the world.
KillHierarchy

SetParent  <string>
Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment  <string>
Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
SetParentAttachmentMaintainOffset  <string>

ClearParent
Removes this entity from the the movement hierarchy, leaving it free to move independently.
AddOutput  <string>
Evaluates a keyvalue/output on this entity.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.
Use  !FGD
Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.
DispatchEffect  <string> !FGD
Dispatches a special effect from the entity's origin. Removed and replaced entirely by the particle system since <Left 4 Dead>.
DispatchResponse  <string> !FGD
Dispatches a response to the entity. See Response and Concept.

Remove a context from this entity's list. The name should match the key of an existing context.
ClearContext  <string>
Removes all contexts from this entity's list.
RunScriptFile  <script> (New with Left 4 Dead 2)
Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
RunScriptCode  <string> (New with Left 4 Dead 2)
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 <Left 4 Dead 2>, the code is executed in the script scope of the entity that fires the output, not the one receiving the input.
Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
CallScriptFunction  <string> (New with Left 4 Dead 2) !FGD
Execute a VScript function in the scope of the receiving entity.

Outputs

DynamicProp:

OnAnimationBegun
Fired when an animation begins.
OnAnimationDone
Fired when an animation finishes.

Breakable (prop):

OnTakeDamage
Fired when damage is taken.

Breakable (common):

OnBreak
Fired when this object breaks. !activator is whatever breaks the object.
OnHealthChanged  <float>
Fired whenever the health of the breakable has increased or decreased. This output automatically puts the new health amount as a decimal percent (e.g. 45% = 0.45) into the parameter box for inputs, if the mapper does not override the parameter with something else.

Model:

OnIgnite
Fired when the entity catches fire, such as from an env_entity_igniter or the Ignite inputs.

Base:

OnUser1 to OnUser4
These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.
OnKilled  (Only in the Left 4 Dead series)
This output fires when the entity is killed and removed from the game. <Left 4 Dead> only.
