添加炸弹数量，当玩家碰撞时不起作用

Question

我在发布此内容之前尝试使用搜索栏，但没有发现任何东西能真正解决我的问题。

当玩家走过“物品”时，它会按预期消失，但是我也希望它在拾取该物品时也向当前编号为 0 的玩家添加一颗炸弹，但它似乎不是在职的？非常感谢任何帮助。

using UnityEditor;

public class shooter : MonoBehaviour
{
public GameObject powercell; //link to the powerCell prefab
public int no_cell = 1; //number of powerCell owned
public AudioClip throwSound; //throw sound
public float throwSpeed = 20;//throw speed
                             // Update is called once per frame
public void Update()
{
    //if left control (fire1) pressed, and we still have at least 1 cell
    if (Input.GetButtonDown("Fire1") && no_cell > 0)
    {
        no_cell--; //reduce the cell
                   //play throw sound
        AudioSource.PlayClipAtPoint(throwSound, transform.position);
        //instantaite the power cel as game object
        GameObject cell = Instantiate(powercell, transform.position,
        transform.rotation) as GameObject;
        //ask physics engine to ignore collison between
        //power cell and our FPSControler
        Physics.IgnoreCollision(transform.root.GetComponent<Collider>(),
        cell.GetComponent<Collider>(), true);
        //give the powerCell a velocity so that it moves forward
        cell.GetComponent<Rigidbody>().velocity = transform.forward * throwSpeed;
    }
}

//
void OnTriggerEnter(Collider other)
{
    if (other.gameObject.tag == "Item")
    {
        no_cell = 1;
        Destroy(gameObject);
    }
}

// Use this for initialization
void Start()
{

}
}

首先将您的脚本更改为以下内容。 如果您仍然没有在控制台中看到 no_cell 增加，请给我们一些屏幕截图，来自您的编辑器，显示附加到游戏对象的脚本，以及您希望看到差异的位置。

public class shooter : MonoBehaviour {
    public GameObject powercell;    //link to the powerCell prefab
    public int no_cell ;            //number of powerCell owned
    public AudioClip throwSound;    //throw sound
    public float throwSpeed = 20;   //throw speed

    // Use this for initialization
    void Start(){
        no_cell = 1;
    }

    // Update is called once per frame
    public void Update()
    {
        //if left control (fire1) pressed, and we still have at least 1 cell
        if (Input.GetButtonDown("Fire1") && no_cell > 0)
        {
            no_cell--; //reduce the cell
                       //play throw sound
            AudioSource.PlayClipAtPoint(throwSound, transform.position);
            //instantaite the power cel as game object
            GameObject cell = Instantiate(powercell, transform.position,
            transform.rotation) as GameObject;
            //ask physics engine to ignore collison between
            //power cell and our FPSControler
            Physics.IgnoreCollision(transform.root.GetComponent<Collider>(),
            cell.GetComponent<Collider>(), true);
            //give the powerCell a velocity so that it moves forward
            cell.GetComponent<Rigidbody>().velocity = transform.forward * throwSpeed;
        }
    }


    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Item")
        {
            no_cell++;              
            Debug.Log("Number of cells:"+no_cell.ToString());
            Destroy(other);
        }
    }


}

如果我做对了，每次你与“项目”发生碰撞时，你想添加 1 个额外的单元格吗？ 那么你应该去 no_cell++ （或者保持原样，如果你的 max no_cell 应该是 1）。

另外，检查其他条件是否会降低您的 no_cell，这可能是您没有看到它增加的原因。

最后，一个建议是使用 Start() 进行初始化（例如 no_cell = 1），如果 no_cell 是指单元格的数量，则使用更接近自然语言的方便命名，例如 cellsNumber。
