Hexagonal movement

Hello,
I've never been using unity before and now I decided to try making a simple 2D game. I'm trying to make hexagonal movement by one tile using mouse click but there is no progress, so I hope to get some help here. I've watched some YouTube tutorials, but I think I need something concrete to make an understanding.

I was wondering if it is more simpler to make it by creating tiles as 3D objects or is there any way to make it using hexagonal grid?

I hope you understood my problem.

 

Ok, first off you'll need to register which tile you're clicking.
The Grid system has ways to easily give you cell centers based on a position: GetCellCenterWorld.
If you use this and make sure that the target cell is only 1 cell away from the current cell, you can do 1 by 1 movement.
Pseudo-code you place on your pawn:

Code (CSharp):

1. if(Input.GetMouseButtonDown(0)) //left mouse click
2. {
3.     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
4.     if(Physics.Raycast(ray, out RaycastHit hit) //Cast a ray from mouse pos down
5.     {
6.         Vector3 newCenter = grid.GetCellCenterWorld(hit.position);
7.         if(transform.position - newCenter <= grid.cellSize)
8.         {
9.             Move(newCenter);
10.         }
11.     }
12. }
13. Move(Vector3 position)
14. {
15.     //Move to the new position, handle this however you like.
16. }
17.  

 

Thank you!
