This entity is
not in the
FGD by default.
See below for instructions on making it available.
env_mine is a point entity available in 
Black Mesa. This is 
Anti-Personnel Mine that was used by HECU to mine some areas where many headcrabs hide under sand. Attempt to touch or damage this entity will cause detonation. Not in original FGD due to presence of func_minefield, you still can add it by your hand (or just use Enhanced Black Mesa FGD).
Bug:Never solid. [todo tested in?]Bug:Doesn't work with most item_ and weapon_ entities. [todo tested in?] Bug:Doesn't explode if another mine is detonated nearby. [todo tested in?] | Cvar/Command | Parameters or default value | Descriptor | Effect |
|---|
sk_mine_damage | 50 | arbitrary number | Explosion damage. |
sk_mine_damage_radius | 128 | arbitrary number | Explosion damage radius. |
sk_mine_bounds_xy | 24 | arbitrary number | Sets bounds in which mine will explode along X and Y axis. Similar to bounding box. |
sk_mine_bounds_z | 64 | arbitrary number | Sets bounds in which mine will explode along Z axis. Similar to bounding box. |
Keyvalues
- Skin
(skin) <integer>
- Some models have multiple skins. This value selects from the index, starting with 0.
- Collisions
(solid) <choices>
- Method of collision for this entity.
Choices
- 0: None
- 1: BSP (QPhysics)
- 2: Bounding Box
- 3: Oriented Bounding Box (Use for runtime spawned rotated brush entities)
- 4: Oriented Bounding Box, constrained to Yaw only
- 5: Custom/Test (Usually no collision with anything)
- 6: VPhysics
|
- Hitbox Set
(hitboxset) <string>
- Sets the
$hboxset to use.
- Body Group
(body or SetBodyGroup) <integer>
- 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++.
- Texture Frame
(texframeindex) <integer> !FGD
- The initial frame number for all animated textures on this entity.
- 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>
- Color tint.
- Render FX
(renderfx) <choices>
- Various somewhat legacy alpha effects. See render effects
- Render Mode
(rendermode) <choices>
- Set a non-standard rendering mode on this entity.
Render Modes
- 0: Normal
- 1: Color
- 2: Texture
- 3: Glow
- 4: Solid/Alphatest
- 5: Additive
- 6: Removed, does nothing
- 7: Additive Fractional Frame
- 8: Alpha Add
- 9: World Space Glow
- 10: Don't Render
|
- 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.
- 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> - Deprecated.
The info_lighting_relative from which to sample lighting instead of the entity's origin. Use Lighting Origin instead.
Base:
- Name
(targetname) <string>
- The name that other entities use to refer to this entity.
- 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
- Origin (X Y Z)
(origin) <coordinates>
- The position of this entity's center in the world. Rotating entities typically rotate around their origin.
Bug:Hammer does not move the entities accordingly in the editor. [todo tested in?]
- 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.
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!
- Spawnflags
(spawnflags) <flags> !FGD
- Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Effects
(effects) <flags> !FGD
- Combination of effect flags to use.
Inputs
Detonate <void>- Detonates the mine.
skin <integer>- Selects a skin from the model's index, starting with 0.
Color <color255>- Sets value for
Color property.
Alpha <integer>- Sets value for
Alpha property.
SetBodyGroup <integer>- Sets the the active
$bodygroup.
Ignite- Makes the entity catch on fire indefinitely.
IgniteLifetime <float>- Makes the entity catch on fire for a given amount of time.
IgniteNumHitboxFires <integer> (removed since 
)- Makes the entity catch on fire with a given number of hitbox fire particles. Does not function correctly in onward.
IgniteHitboxFireScale <float> (removed since )- Makes the entity catch on fire with a given scale for hitbox fire particles. Does not function correctly in onward.
BecomeRagdoll- Kills the entity and creates a client-side ragdoll from the model. Input is only passed if the model contains
$collisionjoints. For other models, phys_convert can be used instead.
SetLightingOrigin <targetname>- Sets the entity's lighting origin to use this entity's position.
SetLightingOriginHack <targetname>
) - Deprecated.
Offsets the entity's lighting origin by their distance from an info_lighting_relative. Use SetLightingOrigin instead.
fademindist <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.
fademaxdist <float>- Sets 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.
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.
Warning:Negative or extremely high values can cause crashes!
CBaseEntity:
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 movement hierarchy, leaving it free to move independently.
FireUser1 to FireUser4- Fires the respective
OnUseroutputs; see User Inputs and Outputs.
Kill- Removes this entity and any entities parented to it from the world.
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.
RemoveContext <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).
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>- As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
Use !FGD- Same as a player invoking +use; no effect in most cases.
SetTeam <integer> !FGD- Changes this entity's team.
TeamNum <integer> !FGD- This input changes value for
TeamNum property.
DispatchResponse <string> !FGD- Dispatches a response to the entity. See Response and Concept.
DispatchEffect <string> (removed since ) !FGD- Dispatches a special effect from the entity's origin; See also List of Client Effects. Replaced by the particle system since .
Outputs
OnIgnite !FGD- 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.
