When prompted, click `Yes` to enable the backends. Unity will restart. * **Generate C# Class:** After Unity restarts, find the `PlayerInputActions.inputactions` file in `Assets/Input`. Select it, and in the Inspector, check the box for "Generate C# Class", then click `Apply`. * **Create InputReader Asset:** Right-click in the `Assets/Input` folder (or another suitable location), go to `Create -> ARPG -> Input Reader`. Assign this asset to the `Input Reader` field on the `PlayerController` component in the Inspector. * **NavMesh Baking:** You'll need to create some ground geometry (like a Plane), mark it as `Navigation Static` in the Inspector, and then bake a NavMesh (`Window -> AI -> Navigation`, go to the `Bake` tab and click `Bake`). * **Tags & Layers:** Ensure your main camera is tagged `MainCamera`. Create layers named "Ground" and "Interactable" (or similar) via `Edit -> Project Settings -> Tags and Layers`. Assign your ground objects to the "Ground" layer and interactable objects (like potential enemies) to the "Interactable" layer. Configure the Layer Masks on the `PlayerController` component accordingly. * **Player GameObject:** Create a GameObject for the player (e.g., a Capsule), tag it "Player", add the `PlayerController`, `PlayerMotor`, `CharacterStats`, and `NavMeshAgent` components. Assign the `InputReader` asset. * **Camera GameObject:** Add the `CameraController` script to your Main Camera object. 2. **Player Combat:** Create a `PlayerCombat` script to handle attacking logic, referencing `CharacterStats` for damage values. 3. **Enemy Prefab:** Create a basic enemy prefab with `NavMeshAgent`, `CharacterStats`, `CombatTarget`, and a simple `EnemyController` script for basic AI (like chasing the player). Make it an `Interactable`. 4. **Animation:** Integrate an Animator component for player and enemy movement/attack animations. 5. **UI:** Start building basic UI for health/mana bars, linking them to the `CharacterStats` events. This initial setup provides the core framework. We can build upon this by adding combat details, enemy AI, skills, inventory, items, quests, and more. Let me know what area you'd like to focus on next.
