About this class

Server-Entity: Nodegraph Hint.

QUAKED info_hint (0 0 0) (-8 -8 -8) (8 8 8) x x x x x x x x x x x x x x x x HINTSF_ALLOWJUMPUP

OVERVIEW

Helper entity for the AI routines. Defines where to go for sensible defense/offensive or other hints.

KEYS

  • "targetname" : Name
  • "hinttype" : Hint type, this controls this hints' purpose. See notes
  • "hintactivity" : Associated animation activity. Once an NPC goes to this node they'll play it
  • "nodeFOV" : Field of view of the node. You'll probably want to set a sensible angle too.
  • "StartHintDisabled" : Whether or not to 'hide' the hint on start, requiring activation to work.
  • "Group" : Hint group definition. Some NPCs are set up to only look for their specific group.
  • "IgnoreFacing" : Whether or not we need to ignore the angle (?), see notes.
  • "MinimumState" : The minimum AI state required to use this hint, see notes.
  • "MaximumState" : The maximum AI state allowed to use this hint, see notes.

SPAWNFLAGS

  • HINTSF_ALLOWJUMPUP (65536) : Allow the AI to 'jump' up this node.

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

Some functionality of this entity was meant to be part of info_node in the original Half-Life (1998). However, that was never completed.

Constructor & Destructor Documentation

◆ info_hint()

void info_hint::info_hint ( void  )

Member Function Documentation

◆ Restore()

void info_hint::Restore ( string  strKey,
string  strValue 
)
virtual

Similar to ncIO::SpawnKey() but for save-game fields.

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

Reimplemented from ncPointTrigger.

◆ Save()

void info_hint::Save ( float  handle)
virtual

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

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

Reimplemented from ncPointTrigger.

◆ Spawned()

void info_hint::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 ncEntity.

◆ SpawnKey()

void info_hint::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 ncIO.

Reimplemented from ncPointTrigger.
