Need Helps :Simple shape animation.

My animation is working fine in torque.exe -show and ShowTool but it is not working in the engine.

this is my code

datablock StaticShapeData(myball)
{
category = "myBall";
shapeFile = "~/data/shapes/superbomb/myball.dts";
};

function StaticShapeData::create(%block)
{
%obj = new StaticShape()
{
dataBlock = %block;
};
return(%obj);
}

function myball::onAdd(%this,%obj)
{
%obj.playThread(0,"root");
}



and I also try to call .dsq by using TSShapeConstructor and It is not working too.

datablock TSShapeConstructor(myball)
{
baseShape = "~/data/shapes/superbomb/myball.dts";
sequence0 = "~/data/shapes/superbomb/myball_root.dsq root";
};


datablock StaticShapeData(myball)
{
category = "myBall";
shapeFile = "~/data/shapes/superbomb/myball.dts";
};

function StaticShapeData::create(%block)
{
%obj = new StaticShape()
{
dataBlock = %block;
};
return(%obj);
}

function myball::onAdd(%this,%obj)
{
%obj.playThread(0,"root");
}

I bring myBall from shapes tree in the world editor and it is not moving at all and I type playThread in the console. It said "unable to find funtion playThread" I walk thru this forum and I still cannot make it. Pleas help me. Thank you
