本文介绍了一个简单的2D游戏中的玩家角色控制脚本，通过Unity引擎实现。该脚本包括了角色的移动、跳跃功能，并加入了地面检测逻辑来判断角色是否处于地面上，从而决定是否能够跳跃。

Player控制脚本

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

public class PlayerController : MonoBehaviour
{
    private Rigidbody2D rb;
    

    public float speed;
    public float jumpForce;

    [Header("Ground Check")]
    public Transform checkTrans;
    public LayerMask checkLayer;//存储可以跳跃的layer
    public float radius;

    [Header("States Check")]
    public bool isGround;
    public bool canJump = false;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        InputCheck();
    }

    void FixedUpdate()//每0.02秒调用，时间固定
    {
        Movement();
        Jump();
        PhysicsCheck();
    }

    private void Movement()//人物移动方法
    {
        float horizontalInput = Input.GetAxis("Horizontal");
        rb.velocity = new Vector2(horizontalInput * speed, rb.velocity.y);
        //翻转人物
        if (horizontalInput != 0){
            //int dir = horizontalInput > 0 ? 1 : -1;
            //transform.localScale = new Vector3(dir, 1, 1);//使用scale实现翻转
            int dir = horizontalInput > 0 ? 0 : -1;
            transform.rotation = Quaternion.Euler(0, dir * 180, 0);
        }
    }

    private void InputCheck()//输入检测
    {
        if (Input.GetKeyDown(KeyCode.W)&&isGround){
            canJump = true;
        }
    }

    private void Jump()
    {
        if (canJump){
            rb.velocity = new Vector2(rb.velocity.x, jumpForce);
            //rb.gravityScale = 4;//跳跃后修改重力大小
            canJump = false;
        }
    }

    private void PhysicsCheck()
    {
        isGround = Physics2D.OverlapCircle(checkTrans.position, radius, checkLayer);
        if (isGround)//回到地面后改回重力的大小
            rb.gravityScale = 1;
        else
            rb.gravityScale = 4;
    }

    private void OnDrawGizmos()
    {
        Gizmos.DrawWireSphere(checkTrans.position, radius);
    }

}
