Unity角色移动和帧动画播放

Learning Tips

角色移动模板

    public float moveSpeed;
    //输入信号值
    public float Dup;
    public float Dright;
    //玩家移动意图
    private float targetDup;//竖直方向
    private float targetDright;//水平方向
    //Mathf.SmoothDamp的ref参数
    private float velocityDup;
    private float velocityDright;
    //自定义按键
    public string keyUp = "w";
    public string keyDown = "s";
    public string keyLeft = "a";
    public string keyRight = "d";
    void Update(){
        //玩家移动意图 得到0 1的移动信号
        targetDup = (Input.GetKey(keyUp) ? 1.0f : 0) - (Input.GetKey(keyDown) ? 1.0f : 0);
        targetDright = (Input.GetKey(keyRight) ? 1.0f : 0) - (Input.GetKey(keyLeft) ? 1.0f : 0);
        //对移动意图值进行平滑插值计算 得到平滑渐变的位移值
        //微分位移值
        Dup = Mathf.SmoothDamp(Dup, targetDup, ref velocityDup, 0.1f);
        Dright = Mathf.SmoothDamp(Dright, targetDright, ref velocityDright, 0.1f);//y WS
        //移动
        transform.Translate(new Vector3(Dright,Dup,transform.position.z)*moveSpeed*Time.deltaTime);
    }

播放帧动画的帧控制器

    public int fps = 10;//fps
    public float timer=0;

    public Sprite[] sprites;//存储图片帧数组
    public SpriteRenderer sr;
    
    void Start() {
        sr = GetComponent<SpriteRenderer>();//获取组件
        moveSpeed = 5;
    }
    void Update(){
        timer += Time.deltaTime;
        //1/fps=一帧所需时间 (timer/一帧所需时间)再取整得到当前帧索引
        int frameIndex = (int)(timer / (1.0f / fps)) %2;
            //frameIndex %= 2;
        sr.sprite = sprites[frameIndex];
    }

防止忘记,记录下来,随时温习
