public class WeaponSwitch : MonoBehaviour
{

    public int weaponID;
    public string weaponName; // 在 unity 中顯示武器名

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        // 切換武器
        if (Input.GetKeyDown(KeyCode.Alpha1)) // 按下數字鍵 1 切換成到狀態 1
        {
            weaponID = 0;
        }
        else if (Input.GetKeyDown(KeyCode.Alpha2))
        {
            weaponID = 1;
        }
        else if (Input.GetKeyDown(KeyCode.Alpha3))
        {
            weaponID = 2;
        }
        else if (Input.GetKeyDown(KeyCode.Alpha4))
        {
            weaponID = 3;
        }

        // 切換武器顯示
        switch (weaponID)
        {
            case 0:
                weaponName = "sword";
                break;
            case 1:
                weaponName = "axe";
                break;
            case 2:
                weaponName = "stick";

            case 3:
                weaponName = "spear";
                break;
