C# 在Unity C中从另一个脚本调用非静态变量

我试图在我的第一个脚本中调用overlapping，当我在它自己的脚本中使用debug.log时，它工作得很好，并提供了所需的结果，但当我尝试调用它时，它总是返回false

第一个脚本：

public class AscendingSquareScript : MonoBehaviour {
    public GameObject ascendingBlock;
    SquareBlockScript squareBlockScript;
    float playerWidth;
    float playerHeight;
    float xPlacement;
    GameObject ascendingSquareHolder;
    public KeyCode moveDown;
    GameObject block;
    public SquareBlockScript value;
    void Start() {
        squareBlockScript = ascendingBlock.GetComponent<SquareBlockScript> () as SquareBlockScript;
        ascendingSquareHolder = GameObject.FindGameObjectWithTag ("AscendingSquareHolder");

        playerHeight = ascendingBlock.gameObject.renderer.bounds.size.y;
        playerWidth = ascendingBlock.gameObject.renderer.bounds.size.x;

        for (int i = 0; i < 6; i++) {
            RandomNumberGenerator ();
            block = Instantiate (ascendingBlock) as GameObject;
            block.transform.position = new Vector3(Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).x + (playerWidth/2) + (playerWidth * xPlacement),  Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).y + playerHeight/2 + (playerHeight*i),0f);
            block.transform.parent = ascendingSquareHolder.transform;
        }
    }

    void Update () {
        if (ascendingBlock.GetComponent<SquareBlockScript> ().getOverLap ())
            Debug.Log ("It is currently working");

        if (Input.GetKeyUp (moveDown)) {
            ascendingSquareHolder.transform.position = ascendingSquareHolder.transform.position + new Vector3(0f, -playerHeight, 0f);
            GeneratingSquares();
        }
    }
}

您需要调用实例上的方法，而不是模板预置

public class AscendingSquareScript : MonoBehaviour {
public GameObject ascendingBlock;
SquareBlockScript squareBlockScript;
float playerWidth;
float playerHeight;
float xPlacement;
GameObject ascendingSquareHolder;
public KeyCode moveDown;
GameObject block;
public SquareBlockScript value;
void Start() {
    squareBlockScript = ascendingBlock.GetComponent<SquareBlockScript> () as SquareBlockScript;
    ascendingSquareHolder = GameObject.FindGameObjectWithTag ("AscendingSquareHolder");

    playerHeight = ascendingBlock.gameObject.renderer.bounds.size.y;
    playerWidth = ascendingBlock.gameObject.renderer.bounds.size.x;

    for (int i = 0; i < 6; i++) {
        RandomNumberGenerator ();
        block = Instantiate (ascendingBlock) as GameObject;
        block.transform.position = new Vector3(Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).x + (playerWidth/2) + (playerWidth * xPlacement),  Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).y + playerHeight/2 + (playerHeight*i),0f);
        block.transform.parent = ascendingSquareHolder.transform;
    }
}

void Update () {
    if (block.GetComponent<SquareBlockScript> ().getOverLap ())
        Debug.Log ("It is currently working");

    if (Input.GetKeyUp (moveDown)) {
        ascendingSquareHolder.transform.position = ascendingSquareHolder.transform.position + new Vector3(0f, -playerHeight, 0f);
        GeneratingSquares();
    }
}
}

所以在块上调用.getOverLap而不是ascendingBlock。但这仅适用于分配给块的最后一个实例。您不能在ascendingBlock上使用该方法，因为它只是用于创建实例的模板预制件。

因此您确实看到了来自SquareBlockScript.OnTriggerEnter2D的“it is”消息，但您没有得到“it is current working”消息？是否有办法将同一变量应用于它的多个实例，而不仅仅是最后一个？在实例化它们时，您必须将它们放入数组或列表中。

public class AscendingSquareScript : MonoBehaviour {
public GameObject ascendingBlock;
SquareBlockScript squareBlockScript;
float playerWidth;
float playerHeight;
float xPlacement;
GameObject ascendingSquareHolder;
public KeyCode moveDown;
GameObject block;
public SquareBlockScript value;
void Start() {
    squareBlockScript = ascendingBlock.GetComponent<SquareBlockScript> () as SquareBlockScript;
    ascendingSquareHolder = GameObject.FindGameObjectWithTag ("AscendingSquareHolder");

    playerHeight = ascendingBlock.gameObject.renderer.bounds.size.y;
    playerWidth = ascendingBlock.gameObject.renderer.bounds.size.x;

    for (int i = 0; i < 6; i++) {
        RandomNumberGenerator ();
        block = Instantiate (ascendingBlock) as GameObject;
        block.transform.position = new Vector3(Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).x + (playerWidth/2) + (playerWidth * xPlacement),  Camera.main.ScreenToWorldPoint(new Vector3(0f,0f,0f)).y + playerHeight/2 + (playerHeight*i),0f);
        block.transform.parent = ascendingSquareHolder.transform;
    }
}

void Update () {
    if (block.GetComponent<SquareBlockScript> ().getOverLap ())
        Debug.Log ("It is currently working");

    if (Input.GetKeyUp (moveDown)) {
        ascendingSquareHolder.transform.position = ascendingSquareHolder.transform.position + new Vector3(0f, -playerHeight, 0f);
        GeneratingSquares();
    }
}
}
