Forums → Programming Forum → Hi Guys, Need help :D

Hi! I want to make a game with some blocks but not tetris and i need a hand .
You know the minigame from professor layton?

In this one you have to change the position of the spheres, in mine you have to put a wooden block out of the game screen.

I started studying programming just a month ago and i'm a noob yet.
The first test i did i used this code to move a block:

[code]
public function DocumentClass()
{
block1 = new Block(100, 200);
addChild ( block1 );
block1.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
block1.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
}

public function mouseDownHandler(evt:MouseEvent):void
{
var object = evt.target;
// we should limit dragging to the area inside the canvas
object.startDrag();

}

public function mouseUpHandler(evt:MouseEvent):void
{
var obj = evt.target;
obj.stopDrag();
}
[/Code]

Whit this code i can move the block everywhere on the screen: that's not what i want.
How can i write a code that give me the possibility of moving on lines set in advance?
I explain better: the blocks have to move in only four directions: up, down, left and right and have to stop or don't move when collide with another block.

I know, i'm noob! That's why i'm here!
Thanks in advance
