PostWorld.js

// 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;

// Turn on collisions, but allow the user to turn it off
Actor.setCollisionSetting( true, false );

// Turn on gravity, but allow the user to turn it off
Actor.setGravitySetting( true, false );

// Hide the avatar
Actor.showAvatar  = false;

// Hide the chat panel
Application.chatPaneVisible = false;

// Set ambient light for the scene
Scene.ambientLightColor = Color(0.5, 0.5, 0.5, 0);

// Create a point light
// var oPointLight = Scene.createPointLight( "SceneLight" );
// oPointLight.position = Vector( 0, 600, -500 );

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

// Create the line object
oLine = Scene.createLine( "FirstLine" );

// Add 4 lines to the line object using a different color for each one
oLine.addLine( Vector( 0.0, 9.6, 0.0 ), Vector( 160.0, 9.6, 0.0 ), Color( 1,0,0,0 ) );
oLine.addLine( Vector( 160.0, 9.6, 0.0 ), Vector( 160.0, 9.6, 160.0 ), Color( 0,0,1,0 ) );
oLine.addLine( Vector( 160.0, 9.6, 160.0 ), Vector( 0.0, 9.6, 160.0 ), Color( 0,1,0,0 ) );
oLine.addLine( Vector( 0.0, 9.6, 160.0 ), Vector( 0.0, 9.6, 0.0 ), Color( 1,1,1,0 ) );

// Add the line object to a scene node and set the position
oLineNode = Scene.createSceneNode( "MyLineNode" );
oLineNode.attachObject( oLine );
oLineNode.position = Vector( 50, 90, -200 );

// Render the lines
oLine.draw();
