Detailed Description

Base class for a game player.

The KPlayer class is the central player object. It holds information about the player and is responsible for any input the player does. For this arbitrary many KGameIO modules can be plugged into it. Main features are:

  • Handling of IO devices
  • load/save (mostly handled by KGamePropertyHandler)
  • Turn handling (turn based, asynchronous)

A KPlayer depends on a KGame object. Call KGame::addPlayer() to plug a KPlayer into a KGame object. Note that you cannot do much with a KPlayer object before it has been plugged into a KGame. This is because most properties of KPlayer are KGameProperty which need to send messages through a KGame object to be changed.

A KGameIO represents the input methods of a player and you should make all player inputs through it. So call something like playerInput->move(4); instead which should call KGameIO::sendInput() to actually move. This way you gain a very big advantage: you can exchange a KGameIO whenever you want! You can e.g. remove the KGameIO of a local (human) player and just replace it by a computerIO on the fly! So from that point on all playerInputs are done by the computerIO instead of the human player. You also can replace all network players by computer players when the network connection is broken or a player wants to quit. So remember: use KGameIO whenever possible! A KPlayer should just contain all data of the player (KGameIO must not!) and several common functions which are shared by all of your KGameIOs.

Constructor & Destructor Documentation

◆ KPlayer() [1/2]

KPlayer::KPlayer ( )

Create a new player object.

It will be automatically deleted if the game it belongs to is deleted.

Definition at line 62 of file kplayer.cpp.

◆ KPlayer() [2/2]

KPlayer::KPlayer ( KGame *  game)

Create a new player object.

It will be automatically deleted if the game it belongs to is deleted. This constructor automatically adds the player to the game using KGame::addPlayer()

Definition at line 67 of file kplayer.cpp.

Member Function Documentation

◆ addGameIO()

bool KPlayer::addGameIO ( KGameIO *  input)

Adds an IO device for the player.

Possible KGameIO devices can either be taken from the existing ones or be self written. Existing are e.g. Keyboard, Mouse, Computerplayer

Parameters
inputthe inut device
Returns
true if ok

Definition at line 219 of file kplayer.cpp.

◆ addProperty()

bool KPlayer::addProperty ( KGamePropertyBase *  data)

Adds a property to a player.

You would add all your player specific game data as KGameProperty and they are automatically saved and exchanged over network.

Parameters
dataThe property to be added. Must have an unique id!
Returns
false if the given id is not valid (ie another property owns the id) or true if the property could be added successfully

Definition at line 394 of file kplayer.cpp.

inline

Query whether this player does asynchronous input.

Returns
true/false

Definition at line 145 of file kplayer.h.

◆ calcIOValue()

int KPlayer::calcIOValue ( )

Calculates a checksum over the IO devices.

Can be used to restore the IO handlers. The value returned is the 'or'ed value of the KGameIO rtti's. this is itnernally used for saving and restorign a player.

Definition at line 273 of file kplayer.cpp.

◆ dataHandler()

KGamePropertyHandler * KPlayer::dataHandler ( )
Returns
the property handler

Definition at line 198 of file kplayer.cpp.

protectedslot

Called by KGameProperty only! Internal function!

Definition at line 411 of file kplayer.cpp.

◆ findProperty()

KGamePropertyBase * KPlayer::findProperty ( int  id) const

Searches for a property of the player given its id.

Parameters
idThe id of the property
Returns
The property with the specified id

Definition at line 389 of file kplayer.cpp.

◆ forwardInput()

bool KPlayer::forwardInput ( TQDataStream &  msg,
bool  transmit = true,

Forwards input to the game object..internal use only.

This method is used by KGameIO::sendInput(). Use that function instead to send player inputs!

This function forwards a player input (see KGameIO classes) to the game object, see KGame, either to KGame::sendPlayerInput() (if transmit=true, ie the message has just been created) or to KGame::playerInput() (if player=false, ie the message was sent through KGame::sendPlayerInput).

Definition at line 142 of file kplayer.cpp.

bool KPlayer::load ( TQDataStream &  stream)
virtual

Load a saved player, from file OR network.

By default all KGameProperty objects in the dataHandler of this player are loaded and saved when using load or save. If you need to save/load more you have to replace this function (and save). You will probably still want to call the default implementation additionally!

Mostly internal function

Definition at line 210 of file kplayer.cpp.

◆ networkPriority()

int KPlayer::networkPriority ( ) const

Returns whether this player can be replaced by a network connection player.

The name of this function can be improved ;-) If you do not overwrite the function to select what players shall play in a network the KGame does an automatic selection based on the networkPriority This is not a terrible important function at the moment.

Returns
true/false

Definition at line 213 of file kplayer.cpp.

◆ networkTransmission()

◆ setNetworkPlayer()

void KPlayer::setNetworkPlayer ( KPlayer *  p)

Sets this network player replacement.

Internal stuff

Definition at line 207 of file kplayer.cpp.

◆ setNetworkPriority()

void KPlayer::setNetworkPriority ( int  b)

Set whether this player can be replaced by a network player.

There are to possible games. The first type of game has arbitrary many players. As soon as a network players connects the game runs with more players (not tagged situation). The other type is e.g. games like chess which require a constant player number. In a network game situation you would tag one or both players of all participants. As soon as the connect the tagged player will then be replaced by the network partner and it is then controlled over the network. On connection loss the old situation is automatically restored.

The name of this function can be improved;-)

Parameters
bshould this player be tagged

Definition at line 216 of file kplayer.cpp.

◆ setTurn()

bool KPlayer::setTurn ( bool  b,
bool  exclusive = true 
)

Sets whether this player is the next to turn.

If exclusive is given all other players are set to setTurn(false) and only this player can move

Parameters
btrue/false
exclusivetrue (default)/ false
Returns
should be void

Definition at line 285 of file kplayer.cpp.

◆ signalNetworkData

void KPlayer::signalNetworkData ( int  msgid,
const TQByteArray &  buffer,
TQ_UINT32  sender,
KPlayer *  me 
)
signal

The player object got a message which was targeted at it but has no default method to process it.

This means probably a user message. Connecting to this signal allowed to process it.

◆ signalPropertyChanged

void KPlayer::signalPropertyChanged ( KGamePropertyBase *  property,
KPlayer *  me 
)
signal

This signal is emmited if a player property changes its value and the property is set to notify this change.

This is an important signal as you should base the actions on a reaction to this property changes.

◆ userId()

int KPlayer::userId ( ) const
inline

Returns the user defined id of the player This value can be used arbitrary by you to have some user idendification for your player, e.g.

0 for a white chess player, 1 for a black one. This value is more reliable than the player id whcih can even change when you make a network connection.

Returns
the user defined player id
