<Left 4 Dead><Left 4 Dead 2> prop_fuel_barrel is a point entity available in the Left 4 Dead series. This is a special destructible physics prop that blows up in several stages when shot.

Keyvalues

Start Fade Dist/Pixels <float>
Distance at which the prop starts to fade (<0 = subtract from fademaxdist).
End Fade Dist/Pixels <float>
Maximum distance at which the prop is visible (0 = don't fade out).
Fade Scale <float>
If you specify a fade in the worldspawn, or if the engine is running under low end/medium end/XBox360, then the engine will forcibly fade out props even if fademindist/fademaxdist isn't specified. This scale factor gives you some control over the fade. Using 0 here turns off the forcible fades. Numbers smaller than 1 cause the prop to fade out at further distances, and greater than 1 cause it to fade out at closer distances.
Base Piece <model path>
Flying Piece 1 <model path>
Flying Piece 2 <model path>
Flying Piece 3 <model path>
Flying Piece 4 <model path>
Detonation Particles <string>
Flying Piece Particles <string>
Sound played when the object explodes. <sound>

Targetname:

Name (targetname) <string>
The targetname that other entities refer to this entity by.
Entity Scripts (vscripts) <scriptlist> (in all games since <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> (in all games since <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.
Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Angles:

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.

Studiomodel:

World Model (model) <string>
The model this entity should appear as. 128-character limit.
Skin (skin) <integer>
Some models have multiple skins. This value selects from the index, starting with 0.
Tip:Hammer's model browser automatically updates this value if you use it to view different skins.
Model Scale (modelscale) <float> (in all games since <Source><Source>)
A multiplier for the size of the model.

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 ShadowDepth (disableshadowdepth) <boolean> (in all games since [Portal 2])
Used to disable rendering into shadow depth (for projected textures) for this entity.
Projected Texture Cache (shadowdepthnocache) <choices> (in all games since [Portal 2])
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.
  • 0 : Default
  • 1 : No cache - render every frame
  • 2 : Cache it - render only once
Disable flashlight (disableflashlight) <boolean> (in all games since [Portal 2])
Used to disable projected texture lighting and shadows on this entity.

Reflection:

Render in Fast Reflections (drawinfastreflection) <boolean> (in all games since [Portal 2])
If enabled, this entity will render in fast water reflections (i.e. when a water material specifies $reflectonlymarkedentities) and in the world impostor pass.

Flags

  • 1 : Start Asleep

Inputs

Targetname:

Kill
Removes this entity from the world.
KillHierarchy
Removes this entity and its children from the world.
Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.
AddOutput <string>
Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O 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 depending on the entity. Can also be invoked by firing an output that does not specify an input.
RunScriptFile <script> (in all games since <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> (in all games since <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> (in all games since <Left 4 Dead 2>) !FGD
Execute a VScript function in the scope of the receiving entity.
SetLocalOrigin <coordinates> (in all games since <Alien Swarm>) !FGD
Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
SetLocalAngles <angles> (in all games since <Alien Swarm>) !FGD
Set this entity's angles.

Studiomodel:

Skin <integer>
Changes the model's skin to the specified number.
SetBodyGroup <integer>
Set the model's body group.
AlternativeSorting <boolean>
Uses an alternative method for telling which objects are in front of others. Use if this object draws incorrectly when seen through transparent things.
SetModelScale <string> (only in <Source><Source>)
Sets the model scale. 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. If there is no second value, the model will scale instantly. Warning: Negative or extremely high values can cause crashes!

Shadow:

DisableShadow
Turn dynamic shadows off for this entity.
EnableShadow
Turn dynamic shadows on for this entity.
DisableReceivingFlashlight  (in all games since [Portal 2])
This object will not receive light or shadows from projected textures.
EnableReceivingFlashlight  (in all games since [Portal 2])
This object may receive light or shadows from projected textures.

Reflection:

DisableDrawInFastReflection  (in all games since [Portal 2])
Turns off rendering of this entity in reflections when using $reflectonlymarkedentities in water material.
EnableDrawInFastReflection  (in all games since [Portal 2])
Turn on rendering of this entity in reflections when using $reflectonlymarkedentities in water material.

ToggleDraw:

DisableDraw  (in all games since [Portal 2])
Add the EF_NODRAW flag to this entity. Some entities manage this on their own so be aware you can override that value.
EnableDraw  (in all games since [Portal 2])
Remove the EF_NODRAW flag from this entity. Some entities manage this on their own so be aware you can override that value.

Outputs

Targetname:

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 <Left 4 Dead><Left 4 Dead 2>)
This output fires when the entity is killed and removed from the game.

Studiomodel:

OnIgnite
Fired when this object catches fire.
