Player grounder cheacker

Questions & Answers
1

I want to know if my player is on the ground or not. I made a little box collider 2d on the bottom of his feet with the tag “groundchecker”.
How do I know if that collider is currently touching somthing?
The box collider is a child of the player.
I am writing in C#.

Thank you for the answers :D.

GameObject player; // initialize this in Start - player = this.gameobject;
public LayerMask IgnorePlayer;

		private void CheckForGroundCollision()
		{
			Vector3 GroundCheckStartPoint = new Vector3(player.transform.position.x, player.transform.position.y + 1f, player.transform.position.z);
			RaycastHit hit;
			if (Physics.SphereCast(GroundCheckStartPoint, .5f, Vector3.down, out hit, 1.1f))
			{
				if (hit.collider.tag == "ground")
				{
					isGrounded = true;
				}
				else
				{
					isGrounded = false;
				}
			}
			else
			{
				isGrounded = false;
			}
