Call of Duty 4: Useful Functions

NOTE: These scripts are only adding functionality into game. They do not add things such as mines, artillery, kaboom etc...

Returns array of all players on the server.

<syntaxhighlight lang="cpp"> getAllPlayers() { return getEntArray( "player", "classname" ); } </syntaxhighlight>

Play local sound on all players.

<syntaxhighlight lang="cpp"> playSoundOnAllPlayers( soundAlias ) { players = getAllPlayers(); for( i = 0; i < players.size; i++ ) players[i] playLocalSound( soundAlias ); } </syntaxhighlight>

Removes all text messages from screen.

<syntaxhighlight lang="cpp"> cleanScreen() { for( i = 0; i < 6; i++ ) { iPrintlnBold( " " ); iPrintln( " " ); } } </syntaxhighlight>

Delete object after time.

<syntaxhighlight lang="cpp"> deleteAfterTime( time ) { wait time; if( isDefined( self ) ) self delete(); } </syntaxhighlight>

Return BOOL (true of false) when player is really alive and playing.

Note: CoD's isAlive() function seems to be bugged.

<syntaxhighlight lang="cpp"> isReallyAlive() { return self.sessionstate == "playing"; }

isPlaying() { return isReallyAlive(); } </syntaxhighlight>

Toggle third person camera.

<syntaxhighlight lang="cpp"> thirdPerson() { if( isDefined( self.tp ) ) { self.tp = undefined; self setClientDvar( "cg_thirdPerson", 0 ); } else { self.tp = true; self setClientDvar( "cg_thirdPerson", 1 ); } } </syntaxhighlight>

Waits for enough players to start game.

<syntaxhighlight lang="cpp"> // Use: waitForPlayers( 3 ); Code after this function call will be executed when there is required number of alive players. waitForPlayers( requiredPlayersCount ) { for(;;) { wait 0.5; count = 0; players = getAllPlayers(); for( i = 0; i < players.size; i++ ) if( players[i] isPlaying() ) count++;

if( count >= requiredPlayersCount ) break; } } </syntaxhighlight>

Return player with that nick name or its part.

<syntaxhighlight lang="cpp"> getPlayerByName( nickname ) { players = getAllPlayers(); for ( i = 0; i < players.size; i++ ) if ( isSubStr( toLower(players[i].name), toLower(nickname) ) ) return players[i]; } </syntaxhighlight>

Return player with that slot number.

<syntaxhighlight lang="cpp"> getPlayerByNum( pNum ) { players = getAllPlayers(); for ( i = 0; i < players.size; i++ ) if ( players[i] getEntityNumber() == pNum ) return players[i]; } </syntaxhighlight>

Return true when victim was killed through world geometry.

<syntaxhighlight lang="cpp"> isWallBang( attacker, victim ) { return !bulletTracePassed( attacker getEye(), victim getEye(), false, attacker ); } </syntaxhighlight>

Feel free to use these functions in your own mod. Just remember to put "Brax" in credits.
