Detailed Description

Server-Entity: Interactive Moving Train.

QUAKED func_tracktrain (0 .5 .8) ? NOPITCH NOUSER NOTSOLID

OVERVIEW

An interactive train that moves along a series of path_track entities. It turns and can respond to user input. It does not necessarily have to.

KEYS

"targetname" : Name
"target" : First node to target.
"killtarget" : Target to kill when triggered.
"dmg" : Damage to inflict upon a person blocking the way.
"snd_move" : Path to sound sample which plays when it's moving.
"snd_stop" : Path to sound sample which plays when it stops moving.

SPAWNFLAGS

NOPITCH (1) : Stop at each path_track until we're triggered again.
NOUSER (2) : Train does not pivot up/down at all.
NOTSOLID (8) : Don't do collision testing against this entity.
FIXED (16) : Fixed orientation. Will not turn, only move.

NOTES

Upon level entry, the func_tracktrain will spawn right where its first path_track node is, as specified in target.

This is so you can light the func_tracktrain somewhere else - like a lonely box somewhere outside the playable area.

If no targetname is specified, the train will move on its own at map-launch.

By default, any func_tracktrain can be interacted with by players. You can restrict the area in which the train can be used with a func_traincontrols entity. You can also set the NOUSER (2) spawnflag to disable it entirely.

TRIVIA

This entity was introduced in Half-Life (1998).

Constructor & Destructor Documentation

◆ func_tracktrain()

void func_tracktrain::func_tracktrain ( void )

Member Function Documentation

◆ Blocked()

void func_tracktrain::Blocked ( entity eBlocker )

virtual

Called whenever out movement is being blocked by an entity.

This is currently only relevant on entities that are of MOVETYPE_PUSH.

Reimplemented from NSTrigger.

◆ ControlCheck()

bool func_tracktrain::ControlCheck ( entity toCheck )

◆ EvaluateEntity()

void func_tracktrain::EvaluateEntity ( void )

virtual

Run each tic after physics are run to determine if we need to send updates over the network.

Reimplemented from NSVehicle.

◆ GetPointBetweenNodes()

vector func_tracktrain::GetPointBetweenNodes ( float percentageValue )

Returns a 3d position between two nodes at the specified progression.

Value between 0.0f - 1.0f, 1.0 being closest to the next node heading forward.

◆ GetTrackNodeBack()

path_track func_tracktrain::GetTrackNodeBack ( void )

Returns the track node (path_track) back of the train.

◆ GetTrackNodeForward()

path_track func_tracktrain::GetTrackNodeForward ( void )

Returns the track node (path_track) ahead of the train.

◆ GetTrainPivotPoint()

vector func_tracktrain::GetTrainPivotPoint ( bool drivingBackwards )

◆ IgnoresPitch()

bool func_tracktrain::IgnoresPitch ( void )

Returns if the train can pitch up/down.

◆ OnPlayerUse()

void func_tracktrain::OnPlayerUse ( void )

virtual

◆ PathClear()

void func_tracktrain::PathClear ( void )

Called when the current path is cleared, and a stop sound is played.

◆ PathDone()

void func_tracktrain::PathDone ( void )

Called when the current path is cleared, and a stop sound is played.

◆ PathMoveBack()

void func_tracktrain::PathMoveBack ( void )

Call to move the tracktrain backward.

◆ PathMoveForward()

void func_tracktrain::PathMoveForward ( void )

Call to move the tracktrain forward.

◆ PlayerInput()

void func_tracktrain::PlayerInput ( void )

virtual

Reimplemented from NSVehicle.

◆ PredictPostFrame()

void func_tracktrain::PredictPostFrame ( void )

virtual

Reimplemented from NSVehicle.

◆ PredictPreFrame()

void func_tracktrain::PredictPreFrame ( void )

virtual

Reimplemented from NSVehicle.

◆ ReceiveEntity()

void func_tracktrain::ReceiveEntity	(	float	flNew,
		float	flChanged
	)

virtual

Client: Handles network updates from the server for the associated entity.

Reimplemented from NSVehicle.

◆ RenderDebugInfo()

void func_tracktrain::RenderDebugInfo ( void )

◆ Respawn()

void func_tracktrain::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 NSSurfacePropEntity.

◆ Restore()

void func_tracktrain::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 NSVehicle.

◆ Save()

void func_tracktrain::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 NSVehicle.

◆ SendEntity()

float func_tracktrain::SendEntity	(	entity	,
		float
	)

virtual

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

Reimplemented from NSVehicle.

◆ Spawned()

void func_tracktrain::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 NSSurfacePropEntity.

◆ SpawnKey()

void func_tracktrain::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 NSSurfacePropEntity.

◆ TransitionComplete()

void func_tracktrain::TransitionComplete ( void )

virtual

Called when the entity has successfully completed a level transition.

Reimplemented from NSIO.

◆ Trigger()

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

virtual

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

Reimplemented from NSTrigger.

◆ UpdateView()

void func_tracktrain::UpdateView ( void )

virtual

Reimplemented from NSVehicle.
