1.图集的切割 

• 刚体最好挂在移动的物体上
• 长时间不运动，刚体会休眠
• 关闭刚体得重力（不需要下落）
• 锁死刚体得Z轴旋转（不需要他旋转）
• 将移动操作移动到FixedUpdate可以修复抖动情况
• 刚体，力的交互最好都放在物理帧里面
• time改为fixeddeltatime 物理帧

碰撞器的条件：要有刚体，一方是运动的（有时会休眠）

抖要放入fixupdat里

public class player : MonoBehaviour {
    public float movespeed=3;
    private SpriteRenderer sr;
    public Sprite[] tankSprite;
    private void Awake()
    {

        sr = GetComponent<SpriteRenderer>();
    }

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        float h = Input.GetAxisRaw("Horizontal");
        transform.Translate(Vector3.right*h*movespeed*Time.deltaTime,Space.World );
        if (h < 0){
            sr.sprite = tankSprite[3];
        }else if (h > 0)
        {
            sr.sprite = tankSprite[1];
        }

        float v = Input.GetAxisRaw("Vertical");
        transform.Translate(Vector3.up*v*movespeed*Time.deltaTime ,Space.World);
        if(v<0){
            sr.sprite = tankSprite[2];
        }else if (v > 0)
        {
            sr.sprite = tankSprite[0];
        }
    }
}
 

public float movespeed=3;

    // Use this for initialization
    void Start () {
        
    }
    
    // Update is called once per frame
    void Update () {
        float h = Input.GetAxisRaw("Horizontal");

按住shift拖拽可以多选，可以制作动画
