prop_ragdoll



$collisionjoints
. prop_ragdoll
is a point entity available in all Source games. It is a VPhysics ragdoll. Ragdolls are collections of physics objects constrained together to simulate a jointed object like a dead body. They are very expensive to simulate.

Death Ragdolls/Ragdoll Transformation
When a NPC/player dies or an entity receives the BecomeRagdoll
input, it normally creates a client-side ragdoll and copies most of its animation and visual data to it. Unlike server-side prop_ragdolls, these client-side ragdolls are handled completely on a per-client basis and are much cheaper and simpler than their server-side counterparts, at the expense of being virtually nonexistent on the server, being inconsistent across client perspectives, and only colliding with entities that have physics objects on the client (e.g. worldspawn
).
However, a NPC will become a server-side ragdoll while it's under any of the following conditions:
- The NPC is inside the volume of a
trigger_serverragdoll
- The NPC is killed by a vehicle in singleplayer
- The gravity gun is supercharged
- The NPC dies on fire while in Alyx darkness mode
- The NPC is a vital ally (e.g.,
npc_alyx
)
These server-side death ragdolls will collide with physics objects and beyond, like any prop_ragdoll, but they are marked as debris and do not collide with each other. They do not collide with themselves either, unlike client-side ragdolls. This is believed to be intentional behavior to reduce performance/networking costs.

Keyvalues
- sequence <integer> !FGD

Bug:Doesn't function.
- Body
(body)
<integer> !FGD - Specifies which body group should be used.
- Override Animation
(angleOverride)
<string> - Filled in by the engine via wc_update_entity. Do not edit by hand except to clear.
- Health
(health)
<integer> (only in)
- The amount of damage the ragdoll takes before gibbing.
- Character Manifest Mimic Name
(MimicName)
<string> (only in)
- Choose a name or a classname from the character manifest to dress the ragdoll.
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:
- 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
$bodygroup
.
- Model Index
(modelindex)
<short> !FGD - Given the number index from dumping the
cl_precacheinfo modelprecache
table, sets entity model to the index.Warning:If an entity has animations that will be played, then the set model also must have its own sequences, else the game crashes.
- Model Scale
(modelscale)
<float> (in all games since)
- A multiplier for the size of the model. Negative values are accepted. Does not alter the physics collisions in most cases, however.
Warning:Negative or extremely high values can cause crashes!
Note:Scale may not appear in
Hammer 4.x, but will appear in-game (tested in
). This is fixed in
Hammer++.
Animating
- Sequence
(sequence)
<integer> !FGD - Default animation sequence for the model to be playing after spawning.
- Playback Rate
(playbackrate)
<float> !FGD - A multiplier of the framerate at which animations are played, negative values are accepted. Default is 1.0.
- Texture Frame
(texframeindex)
<integer> !FGD - The initial frame number for all animated textures on this entity.
Effects - Render
- Start Fade Distance
(fademindist)
<float> - Distance at which the entity starts fading. If 0 or less, the entity will disappear instantly when end fade is hit. The value will scale appropriately if the entity is in a 3D Skybox.
- End Fade Distance
(fademaxdist)
<float> - Distance at which the entity ends fading. If 0 or less, the entity won't disappear at all. The value will scale appropriately if the entity is in a 3D Skybox.
- Fade Scale
(fadescale)
<float> - If specified in the
worldspawn
, or if the engine is running below DirectX 8, entities will fade out even if the fade distances above aren't specified. This value gives more control over when this happens: numbers smaller than 1 cause the entity to fade out at further distances, and greater than 1 cause it to fade out at closer distances. Using 0 turns off the forced fade altogether. See also$noforcedfade
.

Inputs
StartRagdollBoogie
- Begins ragdoll boogie effect for 5 seconds.
Bug:This input is actually supposed to use a parameter for how long the ragdoll should boogie, but it uses the wrong field type in the data description.
Code Fix: In
CRagdollProp
's data description, findDEFINE_INPUTFUNC( FIELD_VOID, "StartRagdollBoogie", InputStartRadgollBoogie )
and replaceFIELD_VOID
withFIELD_FLOAT
.

onward.
BecomeRagdoll
- Kills the entity and creates a client-side ragdoll from the model. Input is only passed if the model contains

<targetname>)
- Deprecated. Offsets the entity's lighting origin by their distance from an
info_lighting_relative

<float>- Sets 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.

SetModelScale
<vector> (only in)
- Multiplies the size of the model. Does not alter the physics collisions in most cases. Can take two values separated by a space, in which case the first value would be the target model scale and the second value would be the number of seconds the change in scale will be spread over. If there is no second value, the model will scale instantly.
Tip:The
modelscale
keyvalue can be AddOutputed as a workaround for other games with this input missing.
