How do I Get my path finding to move in a straight line.

Hi, I'm trying to create a game with movement where you can move a certain amount of squares I got the square to works but my path finding make my sprite get off angle and out of position. Is there something wrong with my path finding or is there setting where I can snap sprite to a grid?

Here is my project: drive.google.com/file/d/0B2J 4XHFiDhFycVZzX3pfWHlKQUU/view?usp=sharing

here is a event simple grid movement maybe you can adapt to your game

Thanks, for the help this is exactly what I needed.

Is there a way to stop the movement on a solid? or out of the layout?

yea you can destroy the green pieces if they are not overlapping the grid tilebackground or are spawned outside that way u cant click them therefor u wont be able to move outside.

here you go i modified the capx a bit. remember to keep the sizes of the grid relatively to 36 pixels or something like that. the grid is based on visual placement.

but u can do it using arrays or other stuff. but this method i find it most simple then most.
