Prototype Completion and Polish

Welcome to the final lesson! In this lesson, you'll learn how to polish your AI Dungeon Explorer prototype with professional touches, optimization, and deployment-ready features.

What You'll Accomplish

In this lesson, you'll complete your prototype by:

  • Optimizing Performance for smooth gameplay
  • Adding Polish Features like audio, effects, and UI
  • Implementing Save/Load System for player progress
  • Creating Build Settings for deployment
  • Testing and Debugging the complete prototype

Step 1: Performance Optimization

Frame Rate Optimization

using UnityEngine;
using System.Collections.Generic;

public class PerformanceOptimizer : MonoBehaviour
{
    [Header("Performance Settings")]
    public int targetFrameRate = 60;
    public float cullDistance = 50f;
    public int maxNPCs = 10;

    [Header("LOD Settings")]
    public float[] lodDistances = { 10f, 25f, 50f };

    private List<GameObject> activeNPCs = new List<GameObject>();
    private Camera playerCamera;

    void Start()
    {
        Application.targetFrameRate = targetFrameRate;
        playerCamera = Camera.main;

        OptimizeScene();
    }

    void OptimizeScene()
    {
        // Optimize lighting
        OptimizeLighting();

        // Optimize textures
        OptimizeTextures();

        // Set up LOD system
        SetupLODSystem();
    }

    void OptimizeLighting()
    {
        // Reduce shadow quality for better performance
        QualitySettings.shadows = ShadowQuality.HardOnly;
        QualitySettings.shadowResolution = ShadowResolution.Low;

        // Optimize light culling
        Light[] lights = FindObjectsOfType<Light>();
        foreach (Light light in lights)
        {
            light.shadowStrength = 0.5f;
            light.range = Mathf.Min(light.range, 20f);
        }
    }

    void OptimizeTextures()
    {
        // Compress textures for better performance
        TextureImporter[] importers = Resources.FindObjectsOfTypeAll<TextureImporter>();
        foreach (var importer in importers)
        {
            if (importer != null)
            {
                importer.textureCompression = TextureImporterCompression.Compressed;
                importer.maxTextureSize = 512;
            }
        }
    }

    void SetupLODSystem()
    {
        // Create LOD groups for complex objects
        GameObject[] complexObjects = GameObject.FindGameObjectsWithTag("ComplexObject");
        foreach (GameObject obj in complexObjects)
        {
            LODGroup lodGroup = obj.AddComponent<LODGroup>();
            SetupLODGroup(lodGroup);
        }
    }
}

Step 2: Audio and Visual Polish

Audio System Implementation

using UnityEngine;
using System.Collections.Generic;

public class AudioManager : MonoBehaviour
{
    [Header("Audio Sources")]
    public AudioSource musicSource;
    public AudioSource sfxSource;
    public AudioSource ambientSource;

    [Header("Audio Clips")]
    public AudioClip[] backgroundMusic;
    public AudioClip[] ambientSounds;
    public AudioClip[] sfxClips;

    [Header("Audio Settings")]
    public float musicVolume = 0.7f;
    public float sfxVolume = 1f;
    public float ambientVolume = 0.5f;

    private Dictionary<string, AudioClip> audioLibrary = new Dictionary<string, AudioClip>();

    void Start()
    {
        InitializeAudio();
        PlayBackgroundMusic();
    }

    void InitializeAudio()
    {
        // Create audio library
        foreach (AudioClip clip in backgroundMusic)
        {
            audioLibrary[clip.name] = clip;
        }

        foreach (AudioClip clip in ambientSounds)
        {
            audioLibrary[clip.name] = clip;
        }

        foreach (AudioClip clip in sfxClips)
        {
            audioLibrary[clip.name] = clip;
        }
    }

    public void PlayBackgroundMusic()
    {
        if (backgroundMusic.Length > 0)
        {
            AudioClip music = backgroundMusic[Random.Range(0, backgroundMusic.Length)];
            musicSource.clip = music;
            musicSource.volume = musicVolume;
            musicSource.loop = true;
            musicSource.Play();
        }
    }

    public void PlaySFX(string clipName)
    {
        if (audioLibrary.ContainsKey(clipName))
        {
            sfxSource.PlayOneShot(audioLibrary[clipName], sfxVolume);
        }
    }

    public void PlayAmbient(string clipName)
    {
        if (audioLibrary.ContainsKey(clipName))
        {
            ambientSource.clip = audioLibrary[clipName];
            ambientSource.volume = ambientVolume;
            ambientSource.loop = true;
            ambientSource.Play();
        }
    }
}

Visual Effects System

using UnityEngine;
using System.Collections;

public class VisualEffectsManager : MonoBehaviour
{
    [Header("Particle Effects")]
    public ParticleSystem[] particleEffects;

    [Header("Post-Processing")]
    public GameObject postProcessingVolume;

    [Header("Lighting Effects")]
    public Light[] dynamicLights;

    public void PlayEffect(string effectName)
    {
        foreach (ParticleSystem effect in particleEffects)
        {
            if (effect.name == effectName)
            {
                effect.Play();
                break;
            }
        }
    }

    public void SetLightingMood(string mood)
    {
        switch (mood.ToLower())
        {
            case "dark":
                SetLightingIntensity(0.3f);
                SetLightingColor(Color.blue);
                break;
            case "bright":
                SetLightingIntensity(1f);
                SetLightingColor(Color.white);
                break;
            case "mysterious":
                SetLightingIntensity(0.6f);
                SetLightingColor(Color.purple);
                break;
        }
    }

    void SetLightingIntensity(float intensity)
    {
        foreach (Light light in dynamicLights)
        {
            light.intensity = intensity;
        }
    }

    void SetLightingColor(Color color)
    {
        foreach (Light light in dynamicLights)
        {
            light.color = color;
        }
    }
}

Step 3: Save/Load System

Game Data Management

using UnityEngine;
using System.Collections.Generic;
using System.IO;

[System.Serializable]
public class GameSaveData
{
    public string playerName;
    public int playerLevel;
    public Vector3 playerPosition;
    public List<string> completedQuests;
    public Dictionary<string, int> npcRelationships;
    public string currentScene;
    public System.DateTime saveTime;
}

public class SaveLoadManager : MonoBehaviour
{
    [Header("Save Settings")]
    public string saveFileName = "gameSave.json";
    public int maxSaveSlots = 5;

    private string savePath;
    private GameSaveData currentSaveData;

    void Start()
    {
        savePath = Path.Combine(Application.persistentDataPath, saveFileName);
        LoadGame();
    }

    public void SaveGame()
    {
        currentSaveData = new GameSaveData();

        // Collect player data
        GameObject player = GameObject.FindGameObjectWithTag("Player");
        if (player != null)
        {
            currentSaveData.playerPosition = player.transform.position;
        }

        // Collect NPC relationship data
        AINPC[] npcs = FindObjectsOfType<AINPC>();
        currentSaveData.npcRelationships = new Dictionary<string, int>();

        foreach (AINPC npc in npcs)
        {
            currentSaveData.npcRelationships[npc.npcData.name] = 
                npc.npcData.relationshipScores.GetValueOrDefault("Player", 50);
        }

        // Set save metadata
        currentSaveData.saveTime = System.DateTime.Now;
        currentSaveData.currentScene = UnityEngine.SceneManagement.SceneManager.GetActiveScene().name;

        // Save to file
        string jsonData = JsonUtility.ToJson(currentSaveData, true);
        File.WriteAllText(savePath, jsonData);

        Debug.Log("Game saved successfully!");
    }

    public void LoadGame()
    {
        if (File.Exists(savePath))
        {
            string jsonData = File.ReadAllText(savePath);
            currentSaveData = JsonUtility.FromJson<GameSaveData>(jsonData);

            // Restore player position
            GameObject player = GameObject.FindGameObjectWithTag("Player");
            if (player != null && currentSaveData != null)
            {
                player.transform.position = currentSaveData.playerPosition;
            }

            // Restore NPC relationships
            if (currentSaveData.npcRelationships != null)
            {
                AINPC[] npcs = FindObjectsOfType<AINPC>();
                foreach (AINPC npc in npcs)
                {
                    if (currentSaveData.npcRelationships.ContainsKey(npc.npcData.name))
                    {
                        npc.npcData.relationshipScores["Player"] = 
                            currentSaveData.npcRelationships[npc.npcData.name];
                    }
                }
            }

            Debug.Log("Game loaded successfully!");
        }
    }
}

Step 4: UI Polish and Menus

Main Menu System

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class MainMenuManager : MonoBehaviour
{
    [Header("UI Elements")]
    public Button newGameButton;
    public Button loadGameButton;
    public Button settingsButton;
    public Button quitButton;

    [Header("Settings Panel")]
    public GameObject settingsPanel;
    public Slider musicVolumeSlider;
    public Slider sfxVolumeSlider;
    public Toggle fullscreenToggle;

    void Start()
    {
        // Set up button listeners
        newGameButton.onClick.AddListener(StartNewGame);
        loadGameButton.onClick.AddListener(LoadGame);
        settingsButton.onClick.AddListener(OpenSettings);
        quitButton.onClick.AddListener(QuitGame);

        // Set up settings
        musicVolumeSlider.onValueChanged.AddListener(SetMusicVolume);
        sfxVolumeSlider.onValueChanged.AddListener(SetSFXVolume);
        fullscreenToggle.onValueChanged.AddListener(SetFullscreen);
    }

    public void StartNewGame()
    {
        SceneManager.LoadScene("GameScene");
    }

    public void LoadGame()
    {
        SaveLoadManager saveManager = FindObjectOfType<SaveLoadManager>();
        if (saveManager != null)
        {
            saveManager.LoadGame();
            SceneManager.LoadScene("GameScene");
        }
    }

    public void OpenSettings()
    {
        settingsPanel.SetActive(true);
    }

    public void QuitGame()
    {
        Application.Quit();
    }

    public void SetMusicVolume(float volume)
    {
        AudioManager audioManager = FindObjectOfType<AudioManager>();
        if (audioManager != null)
        {
            audioManager.musicVolume = volume;
        }
    }

    public void SetSFXVolume(float volume)
    {
        AudioManager audioManager = FindObjectOfType<AudioManager>();
        if (audioManager != null)
        {
            audioManager.sfxVolume = volume;
        }
    }

    public void SetFullscreen(bool isFullscreen)
    {
        Screen.fullScreen = isFullscreen;
    }
}

Step 5: Build Settings and Deployment

Build Configuration

using UnityEngine;
using UnityEditor;
using System.IO;

public class BuildManager : MonoBehaviour
{
    [Header("Build Settings")]
    public string buildPath = "Builds/";
    public string buildName = "AIDungeonExplorer";

    [Header("Platform Settings")]
    public BuildTarget targetPlatform = BuildTarget.StandaloneWindows64;
    public BuildOptions buildOptions = BuildOptions.None;

    public void BuildGame()
    {
        // Set build settings
        EditorUserBuildSettings.SwitchActiveBuildTarget(
            BuildTargetGroup.Standalone, targetPlatform);

        // Create build directory
        if (!Directory.Exists(buildPath))
        {
            Directory.CreateDirectory(buildPath);
        }

        string buildLocation = Path.Combine(buildPath, buildName);

        // Build the game
        BuildPipeline.BuildPlayer(
            GetScenePaths(),
            buildLocation,
            targetPlatform,
            buildOptions
        );

        Debug.Log("Build completed: " + buildLocation);
    }

    string[] GetScenePaths()
    {
        string[] scenes = new string[EditorBuildSettings.scenes.Length];
        for (int i = 0; i < scenes.Length; i++)
        {
            scenes[i] = EditorBuildSettings.scenes[i].path;
        }
        return scenes;
    }
}

Step 6: Final Testing and Debugging

Comprehensive Testing Suite

using UnityEngine;
using System.Collections.Generic;

public class PrototypeTester : MonoBehaviour
{
    [Header("Test Settings")]
    public bool runAllTests = true;
    public bool runPerformanceTests = true;
    public bool runFunctionalityTests = true;

    [Header("Test Results")]
    public List<string> testResults = new List<string>();

    void Start()
    {
        if (runAllTests)
        {
            RunAllTests();
        }
    }

    void RunAllTests()
    {
        testResults.Clear();

        if (runPerformanceTests)
        {
            RunPerformanceTests();
        }

        if (runFunctionalityTests)
        {
            RunFunctionalityTests();
        }

        GenerateTestReport();
    }

    void RunPerformanceTests()
    {
        // Test frame rate
        float fps = 1f / Time.deltaTime;
        if (fps >= 60f)
        {
            testResults.Add("✓ Frame rate test passed: " + fps.ToString("F1") + " FPS");
        }
        else
        {
            testResults.Add("✗ Frame rate test failed: " + fps.ToString("F1") + " FPS");
        }

        // Test memory usage
        long memoryUsage = System.GC.GetTotalMemory(false);
        if (memoryUsage < 100 * 1024 * 1024) // 100MB
        {
            testResults.Add("✓ Memory usage test passed: " + (memoryUsage / 1024 / 1024) + " MB");
        }
        else
        {
            testResults.Add("✗ Memory usage test failed: " + (memoryUsage / 1024 / 1024) + " MB");
        }
    }

    void RunFunctionalityTests()
    {
        // Test player movement
        GameObject player = GameObject.FindGameObjectWithTag("Player");
        if (player != null)
        {
            testResults.Add("✓ Player object found");
        }
        else
        {
            testResults.Add("✗ Player object not found");
        }

        // Test NPC functionality
        AINPC[] npcs = FindObjectsOfType<AINPC>();
        if (npcs.Length > 0)
        {
            testResults.Add("✓ NPCs found: " + npcs.Length);
        }
        else
        {
            testResults.Add("✗ No NPCs found");
        }

        // Test dungeon generation
        AIDungeonGenerator generator = FindObjectOfType<AIDungeonGenerator>();
        if (generator != null && generator.generatedRooms.Count > 0)
        {
            testResults.Add("✓ Dungeon generation working: " + generator.generatedRooms.Count + " rooms");
        }
        else
        {
            testResults.Add("✗ Dungeon generation not working");
        }

        // Test save/load system
        SaveLoadManager saveManager = FindObjectOfType<SaveLoadManager>();
        if (saveManager != null)
        {
            testResults.Add("✓ Save/Load system found");
        }
        else
        {
            testResults.Add("✗ Save/Load system not found");
        }
    }

    void GenerateTestReport()
    {
        Debug.Log("=== PROTOTYPE TEST REPORT ===");
        foreach (string result in testResults)
        {
            Debug.Log(result);
        }
        Debug.Log("=== END TEST REPORT ===");
    }
}
