Finally Made A* Pathfinding Works on Characters

Finally made the A* pathfinding works on a character. Also tested it on multiple characters. Although it also works but needed some fixing for it to work properly. The noticeable problem is when a moving character blocks the way for other characters. I have an idea on how to fix it but won't doing the fixing yet and leave the pathfinding as it is right now.

For now I'll be leaving the pathfinding features as it is and move on to the next task which is making an idle and walking animation for the character.
