How do I get parabolic movement in Unity using Rigidbody2d?

Question

EDIT: It was the Animator after all. Apply Root Motion basically nullifies any physics based work.

I "know" this answer but I can't figure out what can possibly be wrong. My code is in FixedUpdate(). My Rigidbody2D has a Gravity Scale of 4 and a Mass of 1. For whatever reason a Gravity Scale of 1 just isn't strong enough to keep it from floating away. In the pictures below the little cubes should be marking each frame.

Using the below code I get a jagged leap movement. The object shoots upwards and falls like a feather.

if(Game.inputManager.GetKey("Jump").KeyPressed())
{
    yForce = 1000f;
    this.rigidbody2D.AddForce(Vector2.up*yForce);
}

And using another suggestion I distribute the force over a second of time.

if(Game.inputManager.GetKey("Jump").KeyPressed())
    {
        addForceTimer = 1;
        yForce = 1000f;
    }
    addForceTimer -= Time.deltaTime;
    if(addForceTimer > 0)
    {
        this.rigidbody2D.AddForce(Vector2.up*yForce* Time.deltaTime*4);

    }

And I get a more desirable but still just as wrong movement where there is no hang at the top of the jump.

From what I thought I knew neither of these should be happening at all. The object shouldn't be falling at a constant speed like it is. Does anybody have any suggestions?

The character is animated if that can possibly have some sort of effect but I don't imagine it would.

Answer 1

Make sure that if the GameObject is animated that you turn off "Apply Root Motion". It is a setting on the "Animator" component. It will mess with the Physics of the object. I do not know the particulars. But I turned it off and voila, everything works fine now.
