I want this little guy to walk around and when he touches a wall, he can't walk through the wall, but the problem is:

when green flag clicked
forever
    
if <key [ v] pressed?> then
change x by (1)
    
end

end

The problem is that the guy once he touches the wall he no longer moves, because he is touching the wall, and he can't move through walls, and sadly stays in one place. For anyone wondering the wall is multicoloured, so colour detection is eliminated.

Somebody please help!

use sensor sprites, that is, 4 sprites that surround this character and “sense” if the character is touching anything by determining if they themselves are touching something. With this method when a sensor goes off you'll know where from, and can stop movement in that direction.

Your problem is that since he is touching the wall, no scripts occur. Can you give me the project/ scratch blocks so I can see into it?

Sensors are great, but unnecessary. Look here to see what I did- http://scratch.mit.edu/projects/25304926/

That would be true if you had no obstacle otherwise it gets very complicated creating if statements to block out complex areas.

Also there is a glitch in your (joespray) game, you can walk into the bottom right corner, then walk down and out of the map.

Sensors work globally in any area with any kind of boundary, and with as many obstacles as are needed for the project.

THanks for telling me, I will fix it.

it's easy,just use other script,like this.

when green flag clicked
forever
    
if <key [ v] pressed?> then
    
change x by (10)
end
if <touching [edge v] ?> then
    
hide

end
if <not <touching [edge v] ?>> then
    
show
end

end
