I have a pacman game and the pacman moves fine - but whenever the enemy (it's a crab) moves into a wall, I can't get him to move again!    Can anybody help me?

Have you uploaded it to Scratch and if you have can you post a link?

I haven't because it is an edit of a basic one that I made which I can give you a URL for

Aha- I have spotted the problem. You have put "if colour is touching another colour" move so when it is not touching that colour and touching the wall colour it will not move!
I'm trying to find someway to fix this but the problem is your sprite is not moving at all in this version so I have to make it move and then sort out the problem

EDIT- by using the "if touching colour" block i have got it to move. Now then- problem fixing time

Excuse the awful scratchblocks- you get the idea.

when gf clicked
forever if (touching <color pink>)
move (Speed) steps
if (touching (color purple))
turn <(180 degrees anti-clockwise)>
move (Speed) steps
end

I have got this working!! If you want i could upload it to my test account and you can use it then i can. This Method would be to turn the sprite 180 degrees when it touches purple to make it go in the opposite direction

I guess what you are eventually trying to do is to make the walls solid (i don't know how to do this) in which case you would not need to do all this.

@dvd4- dvd- you usually fix peoples scratchblocks, if you are coming round this way could you help me please!

Thanks Ernie!

you may also want to put an "if on edge, bounce" but to be honest, it really isn't necessary unless you wanted it to be more realistic to the laws of gravity...

I would do this.

when gf clicked 
forever
move [1] steps
if <key [up v] pressed?>
set [direction v] to [1]
end
if <key [down v] pressed?>
set [direction v] to [2]
end
if <key [left v] pressed?>
set [direction v] to [3]
end
if <key [right v] pressed?>
set [direction v] to [4]
end
if <(direction) = (1)>
point in direction [0 v]
end
if <(direction) = (2)>
point in direction [180 v]
end
if <(direction) = (3)>
point in direction [-90 v]
end
if <(direction) = (4)>
point in direction [90 v]
end

Fixed.
