Little Adventurer: Learn to make a 3D action game with Unity

Create and reset the Player object, attach the LittleAdventurerAndie mesh as Visual, remove Visual's animator, add the Player Lights Prefab, and set the mesh layer to Player to finish setup.

Set up a Cinemachine virtual camera that follows and looks at player, with framing transposer, zero damping, distance 32, and perspective camera to mimic orthographic visuals with fov 25.

Create a script folder under game folder, add PlayerInput and Character C# scripts, attach them to the player game object as character controller, and open PlayerInput in Visual Studio Code.

Write the PlayerInput script to manage horizontal and vertical input with public float variables, captured in Update via Input.GetAxisRaw('Horizontal') and Input.GetAxisRaw('Vertical'), and reset to zero in OnDisable.

Implement character movement in Unity by wiring PlayerInput to MoveSpeed, calculating and normalizing velocity, aligning to the camera, and moving with a character controller in FixedUpdate.

Implement vertical velocity and gravity, move the player downward when not grounded using isGrounded, apply rotation toward movement with Quaternion.LookRotation, and only rotate when moving; set 180 facing bottom left.

Create a Unity animator controller for the player, add an idle state with the LittleAdventurerAndie_idle clip, enable looping, attach it to the player, and test in play mode.

Set up a looping run animation in Unity with a speed parameter, and connect idle and run transitions to speed, updating the animator in code to reflect movement.

Create a fall animation driven by an airborne bool and Fall state with zero-duration transitions to and from Idle, wire it to update with _cc.isGrounded and set gravity to -20.

Set up the footstep VFX for the player by adding the VFX prefab to a root holder under the visual game object, and disable auto play.

Create a run-state animator behavior script in Unity to trigger footstep VFX by using a StateMachineBehaviour named Player_Run, calling PlayerVFXManager.Update_Footstep(true/false) on state enter and exit.

Create the enemy game object to share the character script and animator controller with the player, setting up the root and avatar for a cohesive workflow.

Bake the navmesh in Unity to define walkable surfaces for enemy AI, setting max slope to zero and slope height to 0.1, so stairs are excluded and blue navmesh appears.

Add and configure a NavMesh agent for enemy AI in Unity, pair it with a character controller, adjust the collider, and set stopping distance to 2 to trigger attacks.

Reuse the same character script for players and enemies, moving the enemy toward the player with NavMeshAgent using SetDestination when distance exceeds the stopping distance, updating the running animation with speed.

Update the player input script to attack on left-click using a bool mouseButtonDown, check Time.timeScale equal 0 for pause menus with Input.GetMouseButtonDown(0), and reset input data in OnDisable.

Update the character script to drive a state machine with FixedUpdate, switch normal to movement, switch to attacking on left-click when grounded, clear input cache, and log result in Unity.
