im making a maze game, but i have no idea on how to fix my figure not in the wall. i want to make it so that my figure does not get stuck in the wall.

unrelated question, how do i make a top down scroller script?

here's the script:

when I receive [maze]
forever
if <not <touching [walls] ?>> then 
if <key [w] pressed?> then
change y by (5)
end
if <key [a] pressed?> then
change x by (-5)
end
if <key [s] pressed?> then
change y by (-5)
end
if <key [d] pressed?> then
change x by (-5)
end
  

else

end
end

what can i do?
