GML Good NPC path finding?

EDIT: Using this guy's tutorial instead:

Spoiler: old post

I'm using code that makes an NPC move, which can be found here:

But it doesn't move in a straight line when moving diagonally. Personally, though this code works "alright", I would really prefer a better system. Any suggestions?

Hi, same problem as before, using a better system now. :/

So, is there a better pathfinding system than using the GRID, or can I make the NPC not jerk up and down when moving diagonally?

ALSO this is the code for my NPC's step event, in case that helps (or I did something wrong)

if (mp_grid_path(global.grid,path,x,y,obj_Character.x,obj_Character.y,true)){
  path_start(path,4,path_action_stop,false);
}
