Unable to find object: '' Attempting to call function 'spawntoken'

Hi all,

I'm experiencing some challenges in getting the following to work: every time a ghoul is hit by an arrow, I want a coin token to be spawned. I got the ghouls, player and arrow to work. When the ghoul being hit is at 0 HP, he calls the function to spawn a token before he is deleted. The problem is that when I run the game, it is unable to find the object. And when I hit a ghoul with an arrow, nothing happens.

I do this through the ghoul.cs file:

function Ghoul::hurt(%this, %damage)
{
%this.hitPoints -= %damage;
if ( %this.hitPoints <= 0 )
{
%token.spawntoken();
%this.safeDelete();
}
}

The spawntoken function is defined in Tokenspawner.cs:

// First create an array to store each token
$TokenSet = new SimSet();

function Token::onAddToScene(%this, %scenegraph)
{
//%this.hitPoints = 100;
$TokenSet.add(%this);
%this.setAnimation(coppercoinanimation);
// This is the name of the animation created in the editor (and present in managed/datablocks)
}


function Token::onLevelLoaded(%this, %scenegraph)
// The intent of this function is to create a first animated sprite without any zombie being hit for testing purposes
{
%this.schedule(1000, "spawntoken");
%this.spawnCount = 0;
}

function Token::spawntoken(%this)
// The intent of this function is to spawn a token when the function is called.
{
%token = new t2dAnimatedSprite("Token" @ %this.spawnCount)
{
scenegraph = %this.scenegraph;
config = "tokenDataBlock";
};
%token.setPosition(%this.getPositionX(), %this.getPositionY() + 10);
%this.spawnCount ++;
}

I've looked through the forum, but no matter what I try I can't get it to work. Any help to get me through this puzzle would be appreciated.

Thanks!
