Scratch

There's a few methods 

Colour Recognition, Hit Tests etc:

The easiest method is this though:

<when green flag clicked>
<if><key[ Right ]pressed?>
<move( 1,2,3 etc: )steps>
<if><touching color[ Black (Or the colour of your walls)
<move( -1,2,3 etc: )steps>
<end>

And then just repeat that for all directions

[/blocks]

I would replace [blocks]<touching color[ Black[blocks]
with [blocks]<touching[ wall[/blocks].

Sprite's work too xD

Although it depends on the project..

Project with a lot of sprites: Use a wall sprite = Easier 
Project with 2 - 3 sprites: Probably simpler to use a colour etc:

^ I can't view projects on school computers at the moment, but it sounds like it might help.
