How do I make tile-based movement like Habbo Hotel?

Well,

to be more specific in what I would want to achieve I will use habbo hotel as an example.

In habbo, you make a room which is separed in tiles/blocks,

for example a room could have 10x10 blocks, and you can move by clicking on those blocks,

so in a 10x10 tiles room you would be able to move in 100 different positions.

I want to make something similar to that,

being able to move by clicking on tiles, instead of moving free the room.

Example of a room and tiles in habbo:

Any idea how could I do that?

Thanks!

Look in the sticky. There's a guide for isometric projection if I'm not mistaken.

Also guides for tile/grid movement
