I'm making a game that is kind of like pac man. Except that you are not allowed to kill the enemies. And I was wondering how I make an enemy that kind of has a mind of its own. So it randomly goes around the maze. Except that I do not want it to go right through parts of the maze. I want it to go as it should so that when it goes around the maze is doesn't touch a wall. Please help me!

You can use the random block to create random numbers, and the if statement to tell which path it will take. Pac-Man ai is a little tougher than regular since they have to not go through walls. Maybe you figure something out using glide blocks and random

I'm pretty sure the enemies should have something like this;

when green flag clicked
forever
    
glide (pick random () to (10)) secs to x: (pick random () to (10)) y: (pick random () to (10))
end

Make something else to make it avoid the walls like

when green flag clicked
if <touching color [#f0f]?> then
    
end

The blank space should make it unable to go through the wall

I tried that but the problem is that I want levels too. And the levels have different pathways… So it would take a LONG TIME to do that! Any other suggestions?

Thanks I will try that but I don't know if it will work. Everyone I'm still open for suggestions!

See http://scratch.mit.edu/projects/23515861/ , it is a good example of a computer having a “mind of its own”

Maybe something like this:

(Steps) //create this variable
repeat until <touching color [#f0f]
change y by (5)
End
change y by (-5)
forever
If <([x position v] of [player v])>(x position)>
Set [steps v] to (5)
Else
Set [steps v] to (-5)
End
repeat until <touching color [#f0f]>
change x by (steps)
End
change x by ((0)-(steps))
If <([y position v] of [player v])>(y position)>
Set [steps v] to (5)
Else
Set [steps v] to (-5)
End
repeat until <touching color [#f0f]>
change y by (steps)
End
change y by ((0)-(steps))

That's the sort of thing I think a grid system is useful for. I did a tutorial here http://scratch.mit.edu/projects/47150778/
