我的角色不会攀登，只会跌落在统一2D中

Question

Im very new to Unity and C# I have been trying to make my character climb on ladders for hours and tried 20+ diffrent scripts but nothing is working.I am putting the script on the collider around the ladder(the ladder is part of the tiles)i even added a spirit behind the tiles where the ladders and put the collider around them but nothing the character just falls(i have put the collider as a trigger)again i am new this was a code i found that a lot of people liked but it seemed not to work for me here is the ladder code:

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

public class Ladder : MonoBehaviour
{

    GameObject playerOBJ;
    bool canClimb = false;
    float speed = 1;

    void OnCollisionEnter(Collision coll)
    {
        if (coll.gameObject.tag == "Player")
        {
            canClimb = true;
            playerOBJ = coll.gameObject;
        }
    }

    void OnCollisionExit(Collision coll2)
    {
        if (coll2.gameObject.tag == "Player")
        {
            canClimb = false;
            playerOBJ = null;
        }
    }
    void Update()
    {
        if (canClimb)
        {
            if (Input.GetKey(KeyCode.W))
            {
                playerOBJ.transform.Translate(new Vector3(0, 1, 0) * Time.deltaTime * speed);
            }
            if (Input.GetKey(KeyCode.S))
            {
                playerOBJ.transform.Translate(new Vector3(0, -1, 0) * Time.deltaTime * speed);
            }
        }
    }
}'

You need to disable the gravity on your character rigidbody while climbing otherwise the gravity will always take your character down.

You can access your character rigidbody like this:

playerRB = playerOBJ.GetComponent<Rigidbody2D>();

you can change the gravity to 0:

playerRB.gravityScale = 0; and back to 1 when you need to.

For instance disable the gravity anytime your character hit the ladder collider and enable the gravity when you press "A" or "D" to make your character fall from the ladder.
