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.

getAllPlayers()
{
	return getEntArray( "player", "classname" );
}

Play local sound on all players.

playSoundOnAllPlayers( soundAlias )
{
	players = getAllPlayers();
	for( i = 0; i < players.size; i++ )
	{
		players[i] playLocalSound( soundAlias );
	}
}

Removes all text messages from screen.

cleanScreen()
{
	for( i = 0; i < 6; i++ )
	{
		iPrintlnBold( " " );
		iPrintln( " " );
	}
}

Delete object after time.

deleteAfterTime( time )
{
	wait time;
	if( isDefined( self ) )
		self delete();
}

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

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

isReallyAlive()
{
	if( self.sessionstate == "playing" )
		return true;
	else
		return false;
}

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

Toggle third person camera.

thirdPerson()
{
	if( !isDefined( self.tp ) )
	{
		self.tp = true;
		self setClientDvar( "cg_thirdPerson", 1 );
	}
	else
	{
		self.tp = undefined;
		self setClientDvar( "cg_thirdPerson", 0 );
	}
}

Waits for enough players to start game.

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

		if( count >= requiredPlayersCount )
			break;
	}
}

Return player with that nick name or its part.

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

Return player with that slot number.

getPlayerByNum( pNum ) 
{
	players = getAllPlayers();
	for ( i = 0; i < players.size; i++ )
	{
		if ( players[i] getEntityNumber() == pNum ) 
			return players[i];
	}
}

Return true when victim was killed through world geometry.

isWallBang( attacker, victim )
{
	start = attacker getEye();
	end = victim getEye();
	if( bulletTracePassed( start, end, false, attacker ) )
		return false;
	return true;
}

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