Pickup and carry rigidbody

Questions & Answers
1

I am trying to pickup and carry a rigidbody weapon, where it will move to a point in front of the player, and move with the player like a child object would, but still react to physics. Right now, I am simply setting the velocity to move towards the position, and adding the player’s rigidbody velocity to the weapon movement velocity. When I do this, the weapon moves to the correct spot, but when I move around, the weapon jerks around. I want it to stay at the spot once it gets to that point. Here’s a 1 showing the problem. This is the code I have…

void FixedUpdate() 
	{
		if (beingHeld) 
		{
			rb.velocity = ((holdPosition - rb.position + (playerObj.GetComponent <Rigidbody>().velocity / Time.deltaTime / 1500)) * Time.deltaTime * 1500);		
		}
	}

Take a look at this open source project I worked on. We made a physics gun similar to that found in garrys mod. github
What I did was create a vector at a point where the gun grabs the object and then calculate the direction and force to get the object to that point.
