Simple Show of Coding

A simple show of how 15 lines of coding can make a simple game. The coding included was velocity variables and a limit to the variables so the object wont go off the play area.

Due to comments here is the code i used?

class ty extends MovieClip

{

var velocity;

function onLoad()

{

velocity = 10;

}

function onEnterFrame()

{

if( Key.isDown(Key.RIGHT) )

{

_x = _x + velocity;

}

if( Key.isDown(Key.LEFT) )

{

_x = _x ? velocity;

}

if( Key.isDown(Key.UP) )

{

_y = _y ? velocity;

}

if( Key.isDown(Key.DOWN) )

{

_y = _y + velocity;

}

}

}

Please donate and help me to make more games thanks everyone.
