C# scripting problem CS0131

Questions & Answers
1

Hi, I’m new to unity and have been trying to create a simple 2D platformer. I am trying to create a block that falls after a delay triggered by touching the player. I attempted to create a script based on things I found online and my own knowledge. I think my code works with exception to the CS0131 error.
Please assist in solving the CS0131 error or give suggestions to improve my code.
Thanks

Code:

using UnityEngine;
using System.Collections;
public class DelayGrav : MonoBehaviour
{
public float delay = 1f;
private float timer = 0f;

void Start ()
{
}
void Update ()
{
}
void OnColliderHit (Collider other)
	{
	timer += Time.deltaTime;

	if (timer > delay) 
		RigidbodyConstraints2D.FreezePositionY = false;
	}

}

You are trying to assign a value to a static, predefined variable.

Rigidbody2D.constraints = RigidbodyConstraints2D.None;
