dragging on a gameObject messes with collisions

Questions & Answers
1

I have a player with movement that works with collisions as long as I don’t click directly on the player before dragging. If I click anywhere else, everything works fine.

I’m not sure what I’m missing and days of research hasn’t resulted in anything. Am I missing something super basic? Each collider has a rigidbody, appropriate settings, and (obviously) colliders. It’s something to do with clicking directly on the gameObject before dragging.

Here’s my code:

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

public class playercontroller : MonoBehaviour
{
    Rigidbody2D rb2d;
    private Vector3 mouseposition;
    private Vector2 direction;
    private float movespeed = 100f;

    // Start is called before the first frame update
    void Start()
    {
        rb2d = GetComponent<Rigidbody2D>();

    }

    void FixedUpdate()
    {
        
        if (Input.GetMouseButton(0))
        {
            followmouse();
        }
    }

    void followmouse()
    {
        mouseposition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        direction = (mouseposition - new Vector3(transform.position.x, transform.position.y-1, transform.position.z)).normalized;
        rb2d.velocity = new Vector2(direction.x * movespeed, direction.y * movespeed);
        
    }

    }

It had nothing to do with the code. I realized that I left a RigidBody2D on a child GameObject and it was creating wacky action.
