I read this article: http://www.policyalmanac.org/games/aStarTutorial.htm, but i don’t understand how is calculated G cost. I know those child’s on corner of his parent have bigger score but there is probably another calculation to check distance from current to start node.
Please help.
In the article,
It was stated that G=10 if you move horizontal or vertical and
G=14 if you go diagonal from one square to another square.
Hence if you move horizontal from start square G = 0+10
where initially G is 0. Then you move vertical or horizontal from there implies G=10+10
and if diagonal means G=10+14
