Input.GetButtonDown("Jump") 通过名称Jump可获取点击事件

void Update()
{
    if ( Input.GetButtonDown("Jump")) {
         Debug.Log("Jump");   
    }
}

在Unity中Edit\Project settings下可以找到输入设置

Rigidbody2D需要和Player(小球)建立关联关系

点击space空格实现小球跳跃

C# 端代码示例

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

public class Player : MonoBehaviour
{

    public Rigidbody2D rb;

    public float moveSpeed;
    public float jumpForce;
    private float xInput;

    // Start is called before the first frame update
    void Start()
    {
        Debug.Log("Jump");
    }

    // Update is called once per frame
    void Update()
    {
        // 获取水平输入
        xInput = Input.GetAxisRaw("Horizontal"); 

        rb.velocity = new Vector2(xInput * moveSpeed, rb.velocity.y);

        if ( Input.GetKeyDown(KeyCode.Space)) {
             rb.velocity = new Vector2(rb.velocity.x, jumpForce);
            Debug.Log(DateTime.Now+"点击跳跃");
        }
    }
}

C# 端代码示例

私有化相关变量

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

public class Player : MonoBehaviour
{

    private Rigidbody2D rb;

    // SerializeField 修饰符可以使私有变量在Unity编辑器中显示
    [SerializeField] private float moveSpeed;
    [SerializeField] private float jumpForce;
    private float xInput;

    // Start is called before the first frame update
    void Start()
    {
        // 获取刚体组件
        rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update()
    {
        // 获取水平输入
        xInput = Input.GetAxisRaw("Horizontal"); 

        rb.velocity = new Vector2(xInput * moveSpeed, rb.velocity.y);

        if ( Input.GetKeyDown(KeyCode.Space)) {
             rb.velocity = new Vector2(rb.velocity.x, jumpForce);
            Debug.Log(DateTime.Now+"点击跳跃");
        }
    }
}
