prop_vehicle_jeep

 prop_vehicle_jeep is a point entity available in the Half-Life 2 series. It is a drivable vehicle with the ability to have a mounted Tau Cannon.

models/buggy.mdl, the Half-Life 2 jeep model

models/vehicle.mdl, the Episode Two jalopy model

Half-Life 2: Episode Two gives the vehicle some additional functionality, including blinking hazard lights, a radar that detects specific targets, a holder for Magnusson devices, and various additional inputs.

Warning:It must be given a model, otherwise the game will crash when loading the map.

Tip: In Episode Two, info_target_vehicle_transition entities can be used to create points that the car is teleported to during a map transition, in case the player leaves it behind.

Note:This entity is unimplemented in Half-Life 2: Deathmatch .

Note:It's possible to use the original buggy model and script in Episode Two, and the Tau Cannon is even still functional if enabled. However, the added hazard lights become misplaced below the car as the original model is missing attachments for them. A modified model could be used to move them to a reasonable position, but the code would need to be modified to remove them entirely like in HL2.

Todo: What exactly needs to be changed?

Note:The Episode Two car is also used in Portal , but the resources aren't included by default. Additionally, the radar causes a crash due to an unregistered user message.

Keyvalues

Enable Gun (EnableGun) <boolean> !FGD

BaseDriveableVehicle:

Starts locked (VehicleLocked) <boolean>

Players cannot enter vehicle until it is unlocked.

BaseVehicle:

Scale of action input / framerate (actionScale) <float>

Todo: How fast the vehicle turns/accelerates?

BasePropPhysics:

Physics Impact Damage Scale (physdamagescale) <float>

Multiplies damage received from physics impacts. 0 means the feature is disabled for backwards compatibility.

Impact damage type (Damagetype) <boolean>

If true (1), damage type is sharp and the object can slice others.

Damaging it Doesn't Push It (nodamageforces) <boolean>

Whether damaging the entity applies force to it.

Scale Factor For Inertia (inertiascale) <float>

Scales the angular mass of an object. Used to hack angular damage and collision response.

Confirm:Doesn't actually affect inertia?

Mass Scale (massscale) <float>

Multiplier for the object's mass.

Override Parameters (overridescript) <string>

A list of physics keyvalues that are usually embedded in the model. Format is key,value,key,value,….

Health Level to Override Motion (damagetoenablemotion) <integer>

If specified, this object will start with motion disabled. Once its health has dropped below this specified amount, it will enable motion.

Physics Impact Force to Override Motion (forcetoenablemotion) <float>

If specified, this object will start motion disabled. Any impact that imparts a force greater than this value will enable motion.

GMODSandbox:

Allow Physics Gun (gmod_allowphysgun) <boolean> (only in )

If set, players cannot use Physics Gun on this entity.

Sandbox Tool Whitelist (gmod_allowtools) <string> (only in )

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!

BaseAnimating:

World Model (model) <string>

The model this entity should appear as. 128-character limit.

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.

• 0: None
• 1: BSP (QPhysics) !FGD
  Bug:In Portal 2, if an entity using QPhysics collisions is hit by Gel, the game will crash!
• 2: Bounding Box
• 3: Oriented Bounding Box (Use for runtime spawned rotated brush entities) !FGD
• 4: Oriented Bounding Box, constrained to Yaw only !FGD
• 5: Custom/Test (Usually no collision with anything) !FGD
• 6: VPhysics

Hitbox Set (hitboxset) <string> !FGD

Sets the $hboxset to use.

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 )

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!

Note:Scale may not appear in Hammer 4.x, but will appear in-game (tested in ). This is fixed in Hammer++.

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.

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

Base:

AddContext <string>

Adds to the entity's list of response contexts. See Context.

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. //// Raw text: "OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"

ClearContext

Removes all contexts from this entity's list.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

FireUser1 to FireUser4

Fires the respectiveOnUseroutputs; see User Inputs and Outputs.

Kill

KillHierarchy

Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster thanKillinput.

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>

Bug:In Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.

Fix:Remove the string argument manually with a text editor.

Note: Backtick characters ` are replaced with quotation marks at runtime, allowing quotation marks to be used when normally not possible.
