My sprite wont move up

#1 Fire up your game, hit the "~" (tilde) key to bring up the console, scroll through the console and check if you have any red text, these will signify syntax errors... also it would be helpful if you copied your console.log and pasted it here :)

#2

function setupT2DScene()

}

should be?

function setupT2DScene() {

}

#3 Is your definition of playerUp all on one line of code like you have posted? You need to break it on to two otherwise you're commenting out the actual work.

// Set the player moving up.
$player.setLinearVelocityY( -10 );

#4 Ok :) If it doesn't work feel free to either post your entire client.cs or e-mail it to me and I'll check it.
