如何让效应者在我的角色统一2d上工作

Question

我试图在我的平台游戏中使用浮力效应器，但由于某些原因，由于我的控制器脚本附加到我的播放器，因此效应器不起作用。下面是我的控制器脚本。

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;


    }

}

当我禁用此脚本时，它可以正常工作。只是想知道如何让效应器与我当前的控制器脚本一起工作。

Answer 1

就是这一行：

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

通过设置速度，您将覆盖物理引擎添加的任何速度 - 包括浮力效应器。如果你想保持物理不受浮力效应器的影响，可以选择一些总和。有很多方法可以实现这一点，具体取决于您想要的行为。

我还建议您将Rigidbody2D存储为变量，以节省您和计算机的时间：

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;
    }
}
