Unity controls whether variables in the script are displayed in the Inspector view

Default

By default, $private$ not displayed,$public$ displays:

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

public class Test : MonoBehaviour
{
    
    
    private Rigidbody2D rigidbody2D;
    private Animator animator;

    public float speed = 5f;
    public float jumpForce = 5f;
}

SerializeField

Through $private$ add[S erialize F ield] [SerializeField]before or above$\left[SerializeField\right]$ allows us to observe the value of private variables:

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

public class Test : MonoBehaviour
{
    
    
    [SerializeField]
    private Rigidbody2D rigidbody2D;
    private Animator animator;

    public float speed = 5f;
    public float jumpForce = 5f;
}

Space

$\left[Space\right]$ can be found inI nspector InspectorAdd interlacing to the$I$$n$$s$$p$$e$$c$$t$$o$$r$ view:

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

public class Test : MonoBehaviour
{
    
    
    [SerializeField]
    private Rigidbody2D rigidbody2D;
    private Animator animator;
    [Space]
    public float speed = 5f;
    public float jumpForce = 5f;
}

Header

$[Header(\dots \dots \left)\right]$ Equivalent toInspector InspectorNotes (categories) under the$I$$n$$s$$p$$e$$c$$t$$o$$r$ view:

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

public class Test : MonoBehaviour
{
    
    
    [SerializeField]
    private Rigidbody2D rigidbody2D;
    private Animator animator;
    [Header("速度设定")]
    public float speed = 5f;
    public float jumpForce = 5f;
}

Range

$\left[Range\right(min,max\left)\right]$ can give an$int,float$ variables limit the value range:

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

public class Test : MonoBehaviour
{
    
    
    [SerializeField]
    private Rigidbody2D rigidbody2D;
    private Animator animator;
    [Header("速度设定")]
    [Range(3f,7f)]
    public float speed = 5f;
    public float jumpForce = 5f;
}

HideInInspector

$\left[HideInInspector\right]$ can make this variable not be displayed in the$In\; the\; Inspector$ panel, when you adjust a variable and do not want to modify it, you can hide it:

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

public class Test : MonoBehaviour
{
    
    
    [SerializeField]
    private Rigidbody2D rigidbody2D;
    private Animator animator;
    [Header("速度设定")]
    [Range(3f,7f)]
    public float speed = 5f;
    [HideInInspector]
    public float jumpForce = 5f;
}
