Npc maker


... 


This is a point entity available in all Source games.
Entity Description
Spawns a class of NPC at its position when told to. Typically used to provide a continuous wave of attackers during an ambush, or to replace killed enemies in a standoff-type situation.
For more control over the properties of the spawned NPCs, see the npc_template_maker
point entity, which uses 'template' NPCs as a base, or the point_template
entity, which is more suited for spawning an entire squad into the appropriate positions.

Enable
- Enables the spawner.

- Disables the spawner.
AddMaxChildren
<integer>- Adds to the number of NPCs that can spawn before the spawner is exhausted. If an exhausted spawner is given some children to spawn, it still wont begin spawning until it is re-enabled with the
Enable
input.
SetMaxChildren
<integer>- Sets the number of NPCs that can spawn before the spawner is exhausted. If an exhausted spawner is given some children to spawn, it still won't begin spawning until it is re-enabled with the
Enable
input.
SetMaxLiveChildren
<integer>- Sets the maximum number of NPCs that can be alive at any one time from this spawner.

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
toFireUser4
- Fires the respective
OnUser
outputs; 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 thanKill
input.
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.

)
- 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 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.

<string> (in all games since) (also in
) !FGD
- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope
(only in) !FGD
- Destroys the script scope of the receving entity.
