Unity collider touch 不作用于玩家

Question

我有 player 和 ground 与 2D 对撞机，玩家应该停在 ground 顶部，但它停在地面底部。

代码

PlayerController

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float moveSpeed;
    private float moveSpeedStore;
    public float speedMultiplier;
    public float speedIncreateMilestone;
    private float speedIncreateMilestoneStore;
    private float speedMilestoneCount;
    private float speedMilestoneCountStore;
    public float jumpForce;
    public float jumpTime;
    private float jumpTimeCounter;
    private bool stoppedJumping;
    private bool canDoubleJump;
    private Rigidbody2D myRigidbody;
    public bool grounded;
    public LayerMask whatIsGround;

    public float groundCheckRadius;
    // private Collider2D myCollider;
    private Animator myAnimator;
    public GameManager theGameManager;
    public AudioSource jumpSound;
    public AudioSource deathSound;

    // Start is called before the first frame update
    void Start()
    {
        myRigidbody = GetComponent<Rigidbody2D>();
        myAnimator = GetComponent<Animator>();

        jumpTimeCounter = jumpTime;
        speedMilestoneCount = speedIncreateMilestone;
        moveSpeedStore = moveSpeed;
        speedMilestoneCountStore = speedMilestoneCount;
        speedIncreateMilestoneStore = speedIncreateMilestone;
        stoppedJumping = true;
    }

    // Update is called once per frame
    void Update()
    {
        grounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround);

        if(transform.position.x > speedMilestoneCount)
        {
            speedMilestoneCount += speedIncreateMilestone;
            speedIncreateMilestone = speedIncreateMilestone * speedMultiplier;
            moveSpeed = moveSpeed * speedMultiplier;
        }

        myRigidbody.velocity = new Vector2(moveSpeed, myRigidbody.velocity.y);

        if(Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0) )
        {
            if(grounded)
            {

            }

            if(!grounded && canDoubleJump)
            {
                myRigidbody.velocity = new Vector2(myRigidbody.velocity.x, jumpForce);
                jumpTimeCounter = jumpTime;

                canDoubleJump = false;
                jumpSound.Play();
            }
        }

        if((Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0)) && !stoppedJumping)
        {
            if(jumpTimeCounter > 0)

                myRigidbody.velocity = new Vector2(myRigidbody.velocity.x, jumpForce);
                jumpTimeCounter -= Time.deltaTime;
            }
        }

        if(Input.GetKeyUp(KeyCode.Space) || Input.GetMouseButtonUp(0))
        {
            jumpTimeCounter = 0;
            stoppedJumping = true;
        }

        if(grounded)
        {
            jumpTimeCounter = jumpTime;
            canDoubleJump = true;
        }

        myAnimator.SetFloat("Speed", myRigidbody.velocity.x);
        myAnimator.SetBool("Grounded", grounded);
    }

    void OnCollisionEnter2D(Collision2D other) {
        if(other.gameObject.tag == "killbox")
        {
            theGameManager.RestartGame();
            moveSpeed = moveSpeedStore;
            speedMilestoneCount = speedMilestoneCountStore;
            speedIncreateMilestone = speedIncreateMilestoneStore;
            deathSound.Play();
        }
    }
}

问题

我应该怎么做才能让我的播放器保持在地面上？

注意：这是我在unity 上的第一个问题，所以如果您需要任何类型的代码或数据，请尽管询问，我会尽力为您提供所需的。

谢谢。

看起来你的对撞机太高了。您会注意到指示对撞机大小和位置的绿色框正在与地面上的正确位置发生碰撞。它的底部只是接触地面的顶部。您只需将碰撞器向下移动到播放器上，使绿色框的底部位于播放器精灵的底部。
