/* !! OUTDATED !! Since 21/12/-20
*
* First we get player's position and then calculate targetPosition with RaycastHit.
* Then we compare whether is hits collider and then if collider is tagged with "Wall"
*
* if it hits and player hasn´t hit it over 100 times, will player be set back at last saved position.
* if it hits and player has hit "wall" tagged collider over 100, will player be returned to starting position.
*
* This is to prevent from player getting stuck and need to boot the game.
*
* Then if targetPosition doesn´t hit the collider which is tagged as "Wall", we check if player has been Freezed.
* If that´s not the case, player may move to the target point.
* At this point our Walk class object is called to change the sprite for the right direction.
*
* Then lastly we have timer that saves new last savePosition every 10 ms.
