Detailed Description

QUAKED env_beam (1 .5 0) (-8 -8 -8) (8 8 8) BEAM_STARTON BEAM_TOGGLE BEAM_RANDOMSTRIKE BEAM_RING BEAM_STARTSPARKS BEAM_ENDSPARKS BEAM_DECAL BEAM_SHADESTART BEAM_SHADEEND

OVERVIEW

Controllable beam effect, akin to lightning. Also known as env_lightning.

KEYS

• "targetname" : Name
• "LightningStart" : Targetname of the entity that acts as starting point for the beam.
• "LightningEnd" : Targetname of the entity that acts as an ending point for the beam.
• "Radius" : If either start/end point is undefined, it'll pick the nearest surface in this specified radius as start/end points.
• "life" : Lifetime of the beam in seconds.
• "StrikeTime" : Time in seconds before the beam reactivates.
• "damage" : Damage per second that's dealt when touching the inner beam.
• "texture" : Path to the sprite to use in place of a texture.
• "BoltWidth" : Thickness multiplier. 0-255 range.
• "NoiseAmplitude" : Amplitude multiplier. 0-255 range.

SPAWNFLAGS

• BEAM_STARTON (1) : Activate the beam at map start.
• BEAM_TOGGLE (2) : Beam can now be toggled off, else StrikeTime + life keys take over.
• BEAM_RANDOMSTRIKE (4) : Use variations in StrikeTime + life keys when set.
• BEAM_RING (8) : Instead of a beam, two points will connect into a ring.
• BEAM_STARTSPARKS (16) : TODO: Start of the beam will spark when set.
• BEAM_ENDSPARKS (32) : TODO: End of the beam will spark when set.
• BEAM_DECAL (64) : TODO: Presumably leaves decals when sparks hit a surface.
• BEAM_SHADESTART (128) : Beam will fade towards the start point when set.
• BEAM_SHADEEND (256) : Beam will fade towards the end point when set.

Respawn()

void env_beam::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 NSRenderableEntity.

SendEntity()

float env_beam::SendEntity ( entity  , float    )

virtual

Called by the engine whenever we need to send a client an update about this entity.

Reimplemented from NSRenderableEntity.

SpawnKey()

void env_beam::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 NSRenderableEntity.

Trigger()

void env_beam::Trigger ( entity  act, triggermode_t  state  )

virtual

Called whenever we're legacy triggered by another object or function.

Reimplemented from NSTrigger.
