trigger_look Class Reference

About this class

Server-Entity: Eye/Vision Based Trigger.

QUAKED trigger_look (.5 .5 .5) ?

OVERVIEW

Triggers itself when a player is inside its volume and is looking at a specific entity within a specified field-of-view cone. It then disables itself.

It's like the beginning in Halo - you know, where you have to look up/down at lights and stuff? No...? Well... ever played Splinter Cell?... Nevermind.

KEYS

• "targetname" : Name
• "target" : Target when triggered.
• "delay" : Delay until target is triggered.
• "killtarget" : Target to kill when triggered.
• "looktarget" : Name of the entity to be looked at. Doesn't have to be solid.
• "looktime" : How long the player must look at the 'looktarget', in seconds.
• "fov" : Area of the view-cone check, 1.0 is straight ahead, 0.0 is in the realm of 90 degrees. Default is 0.9.

TRIVIA

This entity was introduced in Half-Life 2 (2004).

Member Function Documentation

Respawn()

void trigger_look::Respawn ( void  )

virtual

Server: Called when the entity first spawns or when game-logic requests the entity to return to its original spawn state.

Reimplemented from NSBrushTrigger.

Restore()

void trigger_look::Restore ( string  strKey, string  strValue  )

virtual

Similar to NSIO::SpawnKey but for save-game fields.

Whatever you write into file handles within your NSIO::Save() method needs to be read back in here.

Reimplemented from NSEntity.

Save()

void trigger_look::Save ( float  handle )

virtual

Handles saving a copy of this entity to a given filehandle.

Within you want to use the NSIO::SaveFloat() etc. methods to write the internal member attributes to the specified file handle.

Reimplemented from NSEntity.

Spawned()

void trigger_look::Spawned ( void  )

virtual

Called when the entity is fulled initialized.

Any spawn key/value info pairs have already been dealt with. So now we can make full decisions on the entity. Always make sure to call super::Spawned(); inside your method when overriding.

Reimplemented from NSEntity.

SpawnKey()

void trigger_look::SpawnKey ( string  strKey, string  strValue  )

virtual

This method handles entity key/value pairs on map load.

You can easily convert the strValue parameter using the ReadFloat etc. methods that are part of NSIO.

Reimplemented from NSEntity.

Touch()

void trigger_look::Touch ( entity  eToucher )

virtual

Called whenever we're touching another entity.

Reimplemented from NSTrigger.
