如何讓效應器在我的角色統一2D中工作

Question

我試圖在平台器中使用浮力效應器，但是由於某些原因，由於連接到播放器的控制器腳本使效應器無法工作。 以下是我的控制器腳本。

controller.cs

using UnityEngine;
using System.Collections;

public class controller : MonoBehaviour
{

    public float topSpeed = 15f;
    bool facingRight = true;

    bool grounded = false;

    public Transform groundCheck;

    float groundRadius = 0.2f;

    GameObject Player, Player2;
    int characterselect;

    public float jumpForce = 700f;


    public LayerMask whatIsGround;

    void Start()
    {
        characterselect = 1;
        Player = GameObject.Find("Player");
        Player2 = GameObject.Find("Player2");


    }

    void FixedUpdate()
    {

        grounded = Physics2D.OverlapCircle(groundCheck.position, groundRadius, whatIsGround);

        float move = Input.GetAxis("Horizontal");

        GetComponent<Rigidbody2D>().velocity = new Vector2(move * topSpeed, GetComponent<Rigidbody2D>().velocity.y);
        if (move > 0 && !facingRight) //if facing not right then use the flip function
            flip();
        else if (move < 0 && facingRight)
            flip();


    }

    void Update()
    {

        if(grounded&& Input.GetKeyDown(KeyCode.Space))
        {

            GetComponent<Rigidbody2D>().AddForce(new Vector2(0, jumpForce));
        }
        {


        }
        if (Input.GetKeyDown(KeyCode.LeftShift))
        {
            topSpeed = topSpeed * 2;
        }
        else if (Input.GetKeyUp(KeyCode.LeftShift))
        {
            topSpeed = 15;
        }

    }

    void flip()
    {

        facingRight = ! facingRight;

        Vector3 theScale = transform.localScale;

        theScale.x *= -1;

        transform.localScale = theScale;


    }

}

當我禁用此腳本時，它可以正常工作。 只是想知道如何使效果器與當前的控制器腳本一起工作。

Answer 1

是這行：

GetComponent<Rigidbody2D>().velocity = new Vector2(
    move * topSpeed,
    GetComponent<Rigidbody2D>().velocity.y);

通過設置速度，您將覆蓋物理引擎添加的任何速度，包括浮力效應器產生的速度。 如果要使物理不受浮力效應器的影響，請執行某種總和。 有多種方法可以實現此目的，具體取決於您想要的行為。

我還建議您將Rigidbody2D存儲為變量，以節省您和計算機的時間：

using UnityEngine;
using System.Collections;

public class Controller : MonoBehaviour
{
    // ...
    Rigidbody2D rbody2D;

    void Start() {
        // ...
        rbody2D = GetComponent<Rigidbody2D>();
    }

    void FixedUpdate() {
        // One simple example of adding to the velocity.
        // Adds velocity in the x-axis such that the new x velocity
        //   is about equal to topSpeed in the direction we are trying to move.
        // Note that "Vector2.right * deltaVelX" = "new Vector2(deltaVelX, 0)".
        float move = Input.GetAxis("Horizontal");
        float deltaVelX = (move * topSpeed) - rbody2D.velocity.x;
        rbody2D.velocity += Vector2.right * deltaVelX;
    }
}
