Thank you Ashley. However I wanted to see the grid and not the contours of obstacles.
I want to see the grid that is made through the entire layout for moving purposes because even tho i deactivate diagonal movement the movement is not totally straight (when moving the object makes little shortcuts).
I Don't want this. I want it to move like this: completely straight: http://qiao.github.io/PathFinding.js/visual/
There is a grid, i Would like to see the grid because if it's not completely square i understand why the object makes shortcuts even if i put no diagonals.
