An Antlion grub is a larvae-stage antlion. It emits a faint light and drops a health-nugget upon death.
Note:Some keyvalues, flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.
Dedicated Console Variables
- sk_grubnugget_health_small <int>
- Health restored by small health-nugget (Default: 1)
- sk_grubnugget_health_medium <int>
- Default: 4
- sk_grubnugget_health_large <int>
- Default: 6
- sk_grubnugget_enabled <int>
- Whether the grub should drop a health-nugget or not. (Default: 1)
- Entity Scripts
- 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
- 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.
- Pitch Yaw Roll (Y Z X)
- 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.
- Distance at which the prop starts to fade (<0 = use fademaxdist).
- Max fade distance at which the prop is visible (0 = don't fade out).
- If you specify a fade in the worldspawn, or if the engine is running under dx7, 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.
- Global Entity Name
- 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.
- 1 : "Do not automatically attach to surface"
- Removes this entity from the world.
- 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
- Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
<output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
- Fire the
OnUseroutputs; see User Inputs and Outputs.
- 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.
- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
- 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 , 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.
- Execute a VScript function in the scope of the receiving entity.
- 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.
- Set this entity's angles.
- Squash the grub!
- The grub will play excited animations and sound effects for this number of seconds.
- These outputs each fire in response to the firing of the like-numbered
FireUser4Input; see User Inputs and Outputs.
- This output fires when the entity is killed and removed from the game.
- Fired when the grub is stepped on or damaged.
- Fired when the grub is killed.
- Fired when the grub is killed (only by the player).
