Nevermind i have fixed this
i used a If not touching color

Your problem is that you have told the sprite not to move at all if it's touching the color at... you can see where this is going.    To fix this, you should make a sensor sprite that is invisible (set the ghost effect to 100). The sprite will have four different colored sides, to determine which side is hitting something. For example, this is the code for the right 'bumper', assuming it's blue:
(Note this is general code, since I'm not entirely sure how yours works based on that screenshot. You'll have to modify it a bit to make it work with your project.)

When green flag clicked
forever
    if color [blue] is touching color [red]
        set right_test to 1
    else
        set right_test to 0
    end_if
    [code for other 3 bumpers]
end_forever

"right_test_ is a variable that tells the player sprite if is touching a wall to the right. If it is equal to one, it can't move right.
