Trying to make a first person RPG

How do I make controller for the player to use? In first person? I want it to be able to walk around using WASD and look around using the mouse.

( I use Javascript btw )

There is a default one available from unity, it’s in C# though. Right click on Assets → Import Package → Characters. It’s under Standard Assets → Characters → FirstPersonCharacter → Prefabs. Drag and drop the FPSController prefab into the scene.
