monster_alien_controller

Alien Controllers are one of the few flying monster entities in Half-Life.

monster_alien_controller is a point entity available in Half-Life, Half-Life: Opposing Force, and Half-Life: Blue Shift.

A monster_alien_controller is a hostile alien NPC with the ability to fly and shoot purple energy projectiles at the player. Because an Alien Controller is a flying monster entity, it requires info node air point entities to navigate properly. Unlike most monster entities, an alien controller is not gravity affected, meaning that if it is placed mid air in the editor it will spawn at that location mid air in-game.

Note:Some keyvalues, spawnflags, or effect flags might not affect a monster, based on the functionality and coding of the monster.

Pre-Disaster : [256]

Fade Corpse : [512]

Not In Deathmatch : [2048]

Prevent this entity from attempting to spawn when deathmatch (multiplayer) is enabled.

Tip:This is intercepted before the entity spawns (hardcoded in the engine), and as such prevents it from ever contributing to the edict limit. As such, it may be desirable to set this on entities that delete themselves in multiplayer anyway, such as monsters and info_null, to prevent them from contributing towards map spawn edict limit crashes on maps with lots of entities.
