難易度: 初級

In this live training session we will look at creating a multiple choice quiz game. We will create the core game loop - timer, score, win and lose states. We will also show code architecture best practices - keeping data and logic separate, and how to structure a game in a way that makes it easy to maintain and extend. We will look at some of the ways we can extend this in session two.

AnswerData

Code snippet

using UnityEngine;
using System.Collections;

[System.Serializable]
public class AnswerData 
{
    public string answerText;
    public bool isCorrect;
    
}

QuestionData

Code snippet

using UnityEngine;
using System.Collections;

[System.Serializable]
public class QuestionData 
{
    public string questionText;
    public AnswerData[] answers;
}

RoundData

Code snippet

using UnityEngine;
using System.Collections;

[System.Serializable]
public class RoundData 
{
    public string name;
    public int timeLimitInSeconds;
    public int pointsAddedForCorrectAnswer;
    public QuestionData[] questions;

}

DataController

Code snippet

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class DataController : MonoBehaviour 
{
    public RoundData[] allRoundData;


    // Use this for initialization
    void Start ()  
    {
        DontDestroyOnLoad (gameObject);

        SceneManager.LoadScene ("MenuScreen");
    }

    public RoundData GetCurrentRoundData()
    {
        return allRoundData [0];
    }

    // Update is called once per frame
    void Update () {
    
    }
}

MenuScreenController

Code snippet

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class MenuScreenController : MonoBehaviour {

    public void StartGame()
    {
        SceneManager.LoadScene("Game");
    }
}

SimpleObjectPool

Code snippet

using UnityEngine;
using System.Collections.Generic;

// A very simple object pooling class
public class SimpleObjectPool : MonoBehaviour
{
    // the prefab that this object pool returns instances of
    public GameObject prefab;
    // collection of currently inactive instances of the prefab

    // Returns an instance of the prefab
    public GameObject GetObject() 
    {
        GameObject spawnedGameObject;

        // if there is an inactive instance of the prefab ready to return, return that
        if (inactiveInstances.Count > 0) 
        {
            // remove the instance from teh collection of inactive instances
            spawnedGameObject = inactiveInstances.Pop();
        }
        // otherwise, create a new instance
        else 
        {
            spawnedGameObject = (GameObject)GameObject.Instantiate(prefab);

            // add the PooledObject component to the prefab so we know it came from this pool
            PooledObject pooledObject = spawnedGameObject.AddComponent<PooledObject>();
            pooledObject.pool = this;
        }

        // enable the instance
        spawnedGameObject.SetActive(true);

        // return a reference to the instance
        return spawnedGameObject;
    }

    // Return an instance of the prefab to the pool
    public void ReturnObject(GameObject toReturn) 
    {
        PooledObject pooledObject = toReturn.GetComponent<PooledObject>();

        // if the instance came from this pool, return it to the pool
        if(pooledObject != null && pooledObject.pool == this)
        {
            // disable the instance
            toReturn.SetActive(false);

            // add the instance to the collection of inactive instances
            inactiveInstances.Push(toReturn);
        }
        // otherwise, just destroy it
        else
        {
            Debug.LogWarning(toReturn.name + " was returned to a pool it wasn't spawned from! Destroying.");
            Destroy(toReturn);
        }
    }
}

// a component that simply identifies the pool that a GameObject came from
public class PooledObject : MonoBehaviour
{
    public SimpleObjectPool pool;
}
