基于unity的2d動(dòng)畫制造----基于c#說話開辟，類似于《DNF》的2d界面，今朝只有一個(gè)游戲場(chǎng)景。結(jié)不雅圖UI如下圖所示

游戲結(jié)不雅視頻已經(jīng)上傳B站：

2dAnimation游戲

游戲開辟重要步調(diào)：

1.素材收集（來自Unity的Asset Store）

2.UI設(shè)計(jì)（隨心所欲）

3.剛體碰撞規(guī)矩等（csharp代碼）

Hierarchy的┞符體構(gòu)造如下：每個(gè)物體的名稱和它的英文名大年夜概一致。

腳本構(gòu)造如下：

部分PlayerController的代碼如下：

    //是否垂直
    public bool isVertical;

    public float changeDirectionTime = 2;

    private float changeTimer;//急鷂鲼

    private Vector2 moveDirection;//移動(dòng)偏向

    private Animator anim;

    private bool isFixed;//是否被修復(fù)


    // Start is called before the first frame update
    void Start()
    {
        rbody = GetComponent<Rigidbody2D>();//獲取剛體

        moveDirection = isVertical ? Vector2.up : Vector2.right;//斷定是否垂直

        changeTimer = changeDirectionTime;

        anim = GetComponent<Animator>();//獲取anim

        isFixed = false;
    }

    // Update is called>void Update()
    {
        //被修復(fù)，不履行以下所有代碼
        if (isFixed) return;
        changeTimer -= Time.deltaTime;
        if (changeTimer < 0)
        {
            moveDirection *= -1;
            changeTimer = changeDirectionTime;
        }

        Vector2 position = rbody.position;

        Destroy(this.gameObject, 2f);
    }

    // Update is called>void Update()
    {
        
    }
    public void Move(Vector2 moveDirection,float moveForce)

public class CollectAble : MonoBehaviour
{
    //草莓被玩家碰撞時(shí)檢測(cè)的相干類
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called>void Update()
    {

    private void OnTriggerEnter2D(Collider2D collision)
    {
        //檢測(cè)到有PlayerController
        PlayerController pc = collision.GetComponent<PlayerController>();
        if (pc != null)
        {
            if (pc.MyCurrentHealth < pc.MyMaxHealth) {
                pc.ChangeHealth(1);
                Destroy(this.gameObject);
