如何使用C＃使玩家團結一致

Question

我正在嘗試使播放器跳轉，但是我在rb.AddForce的fixedUpdate中收到錯誤消息“由於它是一個方法組，因此無法分配給AddForce”，但是在添加跳轉速度和跳轉功能之前它起作用了，我該如何使其工作？

碼：

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class PlayerController : MonoBehaviour {

public float speed; //Creates Speed Variable
public Text countText; //Creates Count Text Variable
public Text winText; //Creates Win Text Variable
public float JumpSpeed;

private Rigidbody rb; //Creates Rigidbody Variable
private int count; //Creates Count Variable

void Start ()
{
    rb = GetComponent<Rigidbody>(); //sets variable for Rigidbody
    count = 0;
    SetCountText ();
    winText.text = "";
}

void FixedUpdate () //Controls
{
    float moveHorizontal = Input.GetAxis ("Horizontal");
    float moveVertical = Input.GetAxis ("Vertical");
    float moveForward = Input.GetAxis ("Forward");

    Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

    rb.AddForce = (movement * speed);

    if (Input.GetKeyUp (KeyCode.Space)) 
    {
        JumpSpeed = 5.0f;
        Vector3 jump = new Vector3 (0.0f, moveForward, 0.0f);
    }

}

void OnTriggerEnter(Collider other) //Collect Items
{
    if (other.gameObject.CompareTag ("Pickup")) {
        other.gameObject.SetActive (false);
        count = count + 1;
        SetCountText ();
    }
}

void SetCountText() //Updates Count Text
{
    countText.text = "Count: " + count.ToString ();
    if (count >= 8) 
    {
        winText.text = "You Win!"; //Displays Win Text
    }
}

}

AddForce是一種方法，而不是屬性。 方法必須被調用，您無需為其分配值。 嘗試

rb.AddForce(movement * speed);

除此之外，也許您應該更深入地了解編程基礎知識。 您可以將方法與屬性區分開來，因為方法名稱通常以動詞（“ AddForce”，“ CreateObject”等）開頭，而屬性名稱很好地描述了屬性（“ Color”，“ VerticalSpeed”，“ Name”，“。”）。 ..）
