Scratch

to stop sprites going through walls:

forever
if <key [left v] pressed>
change x by (variable)//this can be any number or variable if you've used that instead
if <touching [walls v]>//or colour blue, just that I'm not totally sure how to do colours on ScratchBlocks!
change x by ((variable)*-[1])
end
end
if <key [right v] pressed>
change x by (variable)
if <touching [walls v]>
change x by ((variable)*[-1])

it needs a question mark at the end

Also, that script just makes you go left all the time.

Also, it's good to give variables meaningful names, this one looks like it should be called 'speed'

Also to do colours, just type it in hexadecimal inside square brackets (look it up on wikipedia)

forever
if <key [left v] pressed?>
change x by (speed)
if <touching color [#0000ff]?>
change x by ((speed)*[-1])
end
end
if <key [right v] pressed?>
change x by ((speed)*[-1])
if <touching color[#0000ff]?>
change x by (speed)
