moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= walkSpeed;

LAYERS

Layer is an important part of unity. When you try to make a games , you need a lot of objects and you need to make sure which layer you actually want to use. Unity has a options for those layers known as sorting layer.

For Example:

You make a games and in the inspector section you set player and ground both default or same layer and add physics . When you start the game and notice that your player falling or moving through the game objects like tree or walls . this the reasons you set the in the same layer.

How To Solve?

Just click on a game objects and in the inspector section you can see a layer option in the top corner , click and find a option names add sorting layer and here you can add a lot of layers you want. Create layers and set the player and the games objects in different layer.
