How start my game in third person?

I would like start my game in third person.
I tried to use the function togglefirstperson(1) in the function createPlayer but sometimes
game crash in mission loading.

function GameConnection::createPlayer(%this, %spawnPoint)
{
if (%this.player > 0) {
// The client should not have a player currently
// assigned. Assigning a new one could result in
// a player ghost.
error( "Attempting to create an angus ghost!" );
}

// Create the player object
%player = new Player() {
dataBlock = PlayerBody;
client = %this;
};

// create advanced camera
%this.advCamera = new AdvancedCamera()
{
dataBlock = AdvCameraData;
};
MissionCleanup.add(%this.advCamera);
%this.advCamera.scopeToClient(%this);
MissionCleanup.add(%player);

// Player setup...
%spawnPoint = pickSpawnPoint();
%player.setTransform(%spawnPoint);
%player.setShapeName(%this.name);

%player.setInventory(Gun,1);
%player.setInventory(GunAmmo, Gun.initialAmmo);
%player.mountImage(GunImage, 0);
%player.availableWeapons[%weapNum++]= Gun.getId();

GunImage.onReload(%player, $WeaponSlot);

%this.camera.setTransform(%player.getEyeTransform());

%this.player = %player;
%this.setControlObject(%player);

// Camera settings
%this.advCamera.setPlayerObject(%player);
%this.advCamera.setThirdPersonMode();
%this.advCamera.setFollowTerrainMode(true);

$firstPerson=false;
%this.advCamera.Mode = 0;
%this.advCamera.setLookAtOffset("0.0 3.8 1.8");
%this.advCamera.setThirdPersonOffset("0.0 -7.0 7.0");
%this.advCamera.setVerticalFreedomMode(true);
$verticalFreedomMode=true;
%this.setCameraObject(%this.advCamera);
$firstPerson=true;
toggleFirstPerson(1);
}

I resolved with a trick but I looking for a best solution.
I add this function in client/script/ServerConnection.cs
function StartThirdPerson()
{
ServerConnection.setFirstPerson( false );
}
and then I add schedule(150, 0, StartThirdPerson);
in function GameConnection::initialControlSet below Canvas.setContent.

Help me please.


Thanks in advance.
