Hey guys i am currently making a pacman remake in greenfoot but I'm having trouble with getting pacman to move like he does in the original game, moving forward and turning only when there is a path available basically i need to make the actor (pacman) only turn if there is an available path for him to turn into

You could make use of your mazeMap in your World subclass. Make it public or add a public method to get the value of a "cell". The coordinates of the "cell" that pacman would currently be in is: 
int cellX = getX()/30;
int cellY = getY()/30;
You would then change Pacman object movement methods to check what is at a potential target location. For example (again, using jump method code): 
if (((Frog_World)getWorld()).mazeMap[cellY-1][cellX]) == 0)

…… that sounds like it is a great idea but don't really understand how to use it or where to put it..... could u explain it in a simpler way

I do not know what more I can say about it. I gave what to use as well as what to do and where.

obviously in an Actor subclass; however, this was given to show how to get the map coordinates -- not necessarily (but could be) used as is in your code (the right side is the important thing, showing a conversion to map coordinates) You would then change Pacman object movement methods to check what is at a potential target location. For example (again, using jump method code): 
if (((Frog_World)getWorld()).mazeMap[cellY-1][cellX]) == 0)
Most likely "< 2" should be used instead of "== 0". or, you can explicitly name the possible values of cell that can be traversed: 
if ("0 1 2".indexOf(""+((Frog_World)getWorld()).mazeMap[cellY-1][cellX]) >= 0)
