npc_maker is a point entity available in 
Half-Life 2 series, 
Portal (series), 
Team Fortress 2, 
Alien Swarm, and 
Half-Life: Source.
AltNames: In Half-Life: Source and 
Half-Life Deathmatch: Source, this entity is also tied to monstermaker. 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.

Inputs
BaseNPCMaker:
Spawn- Spawns an NPC.
Toggle- Toggles the spawner enabled/disabled state.
Enable- Enables the spawner.
Disable- 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
Enableinput.
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
Enableinput.
SetMaxLiveChildren<integer>- Sets the maximum number of NPCs that can be alive at any one time from this spawner.
SetSpawnFrequency<float>- Sets how often (in seconds) a new NPC will be spawned.
Outputs
BaseNPCMaker:
OnSpawnNPC<string>- Fired when an NPC is spawned. The activator is the NPC, and the string is the name of the NPC.
OnAllSpawned- Fired when the spawned is exhausted (all children have been spawned).
OnAllSpawnedDead- Fired when the spawner is exhausted (all children have been spawned) and all spawned children have died.
OnAllLiveChildrenDead- Fired when all spawned children have died. This does not mean the spawned is exhausted, so a new child may be spawned any time after this (unless the maker is disabled).

npc_template_maker- Uses template NPC entities for more control over spawned NPCs.point_template- Spawns NPCs (or other entities) in-place; can deal with up to sixteen different targetnames simultaneously, and multiple entities per targetname.
