Sorry for my poor English guys :smiley:

I have some problem with this method.
I tried to make the object jump. But “isGrounded” randomly sets to “true” when groundCheck is not in position of “Ground”-layer objects.

How can I fix this problem?

There is a code from Update:

    var ballPos: Vector2 = new Vector2 (ballContainer.transform.position.x, ballContainer.transform.position.y);

	var grCheckPos: Vector2 = new Vector2 (groundCheck.position.x, groundCheck.position.y);

	isGrounded = Physics2D.Linecast(ballPos, grCheckPos, 1 << LayerMask.NameToLayer("Ground"));
	
	if (isGrounded)
	{
		Debug.Log("Grounded");
		jumpCheck = true;
	}
	
	if (!isGrounded)
	{
		jumpCheck = false;
		
	}

Wow, we so often see questions about collisions not occurring, it’s almost refreshing to see a question about mystery collisions instead. It’s also much easier to find out what’s happening.

You could try something like:

RaycastHit2D GroundCheck = Physics2D.Linecast(ballPos, grCheckPos, 1 << LayerMask.NameToLayer("Ground"));
if (GroundCheck) Debug.Log("Ground hit " + GroundCheck.collider.name + " at " + 
    GroundCheck.point.ToString() + "(" + ballPos.ToString() + " - " +
    grCheckPos.ToString() + ")");

Then you’ll be able to see exactly what and where the Linecast is “randomly” intercepting something.
