n Unity, 2D collision detection can be implemented without using Rigidbody components. One way to do this is to use the Collider2D component and the OnCollisionEnter2D or OnTriggerEnter2D methods of the MonoBehaviour class.

You can attach a Collider2D component to a GameObject, and then write a script that has a method such as OnCollisionEnter2D or OnTriggerEnter2D. The OnCollisionEnter2D method will be called when the GameObject with the Collider2D component collides with another GameObject that also has a Collider2D component, while OnTriggerEnter2D will be called when a GameObject with a Collider2D component and is marked as a trigger collides with another GameObject.

For example, you can create a script called "PlayerCollision" and attach it to the player GameObject. In the script, you could have a method such as the following:

void OnCollisionEnter2D(Collision2D collision)
{
    // Code to handle the collision
}
This method will be called whenever the player GameObject collides with another GameObject that has a Collider2D component. You can access information about the collision, such as the colliding GameObject and contact points, through the Collision2D parameter.

You could also do this by using the built-in 2D physics engine by raycasting in specific direction. By doing so you can check if there is a collision object on the certain direction and do certain action based on that.
