I am making a game and I wanted to make a pathfinding AI for it. The issue is it isn't in a grid so I think if I can make sprites walk in a line it can work. How can I make a sprite walk in a line? Is it posibble?

Do you mean following a pre-drawn line or just moving straight?

I meant a pre-drawn line like drawn by a pen. I know how to make sprites go straight to another sprite

Does it know the coordinate of the start and end of the line or not. If not then use:

when green flag clicked
forever
if <touching color [#000000] ?> then 
turn ccw (2) degrees
else
turn cw (2) degrees
end
move (pick random (0.9) to (1.1)) steps
end

If you know the coordinates of a straight line then you can use trig to work out the angle to face then just move straight. For a curve it is more difficult, esp if you need it to move a constant speed.
