what body your character use? the body have signals when you attach script to them.

C# signals

CharacterBody
// Using MoveAndCollide.
var collision = MoveAndCollide(Velocity * (float)delta);
if (collision != null)
{
    GD.Print("I collided with ", ((Node)collision.GetCollider()).Name);
}

// Using MoveAndSlide.
MoveAndSlide();
for (int i = 0; i < GetSlideCollisionCount(); i++)
{
    var collision = GetSlideCollision(i);
    GD.Print("I collided with ", ((Node)collision.GetCollider()).Name);
}

Using CharacterBody2D/3D

My player uses a character body 2D

Did you run code from above?
if you don’t like names you can check if object is class of Player
if(collision.GetCollider() is Player){ … }

Im not sure if this is important but i have a area 2d on the object i want to check collision with and collision shape 2d as a child of it, the code didnt seem to work, but i am also able to walk through the object so that might be a problem on my end

Area2D use signals for Collisions
you can connect your method via editor

in advanced you can pick method to connect

remember your method needed have same arguments to signal (in area is Node2D).
or with Code

public partial class DialogArea : Area2D
{


        public override void _Ready()
        {
                BodyEntered += MyMethod;
        }

        private void MyMethod(Node body)
        {
                if (body is Player player)
                {
                        player.MyStuff();
                }
         }
}

Instead of using an area2D i switched it to static body2D and that has seemed to fix my problems for now
