Question

我试图通过附加此脚本来模拟对象附近物体的重力影响;要做到这一点，我尝试向对象添加一个力量。但是我遇到other.attachedRigidbody.AddForce()的问题我收到以下错误：

无法转换方法组＆＃39; forceCalculation＆＃39;非委托类型＆＃39; UnityEngine.Vector3＆＃39;。考虑使用括号来调用该方法。

public class planetaryForce : MonoBehaviour {
    public float gravityPower;
    public GameObject planetaryCore;
    public float range;

    void OnTriggerEnter(Collider other){
        if (distance (other.gameObject) < range) {
            other.attachedRigidbody.AddForce (forceCalculation(other.gameObject), ForceMode.Acceleration);
        }
    }

    public float distance(GameObject other){
        float distance = Vector3.Distance (other.transform.position, transform.position);
        return distance;
    }

    public Vector3 direction(GameObject other){
        Vector3 direction = transform.position - other.gameObject.transform.position;
        return direction;
    }

    public float multiplier(GameObject other){
        float multiplier = range - distance(other);
        return multiplier;
    }

    public Vector3 forceCalculation(GameObject other){
        forceCalculation = direction(other) * multiplier(other);
        return forceCalculation;
    }
}

Answer 1

在forceCalculation()中，您要返回forceCalculation()方法，而应该做什么：

...
public Vector3 forceCalculation(GameObject other){
    Vector3 calculation = direction(other) * multiplier(other);
    return calculation;
}

Answer 2

public Vector3 forceCalculation(GameObject other) {
    forceCalculation = direction(other) * multiplier(other);
    return forceCalculation;
}

第一行声明一个名为forceCalculation的方法。

然后第二行尝试将Vector3分配给先前注册的名称forceCalculation（这是一种方法）。

通过声明变量来解决此问题：

public Vector3 forceCalculation(GameObject other) {
    Vector3 forceCalculation = direction(other) * multiplier(other);
    return forceCalculation;
}

无法转换方法组＆＃39; ###＆＃39;到非委托类型UnityEngine.Vector3
