Question (new dev) 2d rigidbody2d not working with collision [solved]

hi so i tried to use rigidbody2d and a box collider and a collision layer to block my player from moving into certain objects in the environment but i cant seem to make it work i would really appreciate the help as I'm really new to unity and don't really know what to do,
my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public class playerController : MonoBehaviour
{
// Start is called before the first frame update
public float moveSpeed=1f;
public float collisionOffsett=0.05f;
public ContactFilter2D movementFilter;
Vector2 movmentInput;
Rigidbody2D rb;
List<RaycastHit2D> castCollisions = new List<RaycastHit2D>();
void Start()
{
rb = GetComponent<Rigidbody2D>();
}

// Update is called once per frame
void Update()
{

}
private void FixedUpdate(){
if(movmentInput!=Vector2.zero){
int count= rb.Cast(
movmentInput,
movementFilter,
castCollisions,
moveSpeed*Time.fixedDeltaTime+collisionOffsett
);
if(count==0){
rb.MovePosition(rb.position+movmentInput*moveSpeed*Time.fixedDeltaTime);
}
}
}
void OnMove(InputValue movmentValue){
movmentInput= movmentValue.Get<Vector2>();
}
}
screengrab of my scene with the collider

please help it is really appreciated

 

I don't see any green collider on the player. Is that just because he's not selected?

Why not press play, pause, then drop a sprite into the scene with a collider and rigidbody2d and see if it bounces on your level chunks?

 

it was because he wasn't selected also after using your trick i realized "is trigger" wasn't active, at least i solved it now, ty
