// Turn on debug so that Chat.printDebug() and Chat.dump() work
Chat.debugOutput = true;

// Display the stats panel in the bottom left corner of screen
Application.statsVisible = true;

// Set ambient light for the scene
Scene.ambientLightColor = Color(0.25, 0.25, 0.25, 0);

// Create the floor
var oGround = Scene.createGround( "MainFloor", "RustySteel", 3000.0, 3000.0, true );

// Add the Ogre head
oHeadEntity = Scene.createEntity( "OgreHead", "ogrehead.mesh" );
oHeadNode = Scene.createSceneNode( "OgreHeadNode" );
oHeadNode.attachObject( oHeadEntity );
oHeadNode.position = Vector( 0, 175, -500 );

// Create the Distant light
oDistantLight  = Scene.createDistantLight( "DistantLight" );

// Set the direction that the light points
// It will come from the back of the Ogres head,
// leaving the face dark and the back of the head light
oDistantLight.direction = Vector( 0, -0.5, 0.5 );
