How I can identify if the player is going up or down?

Well… I making a metroidvania game, and I need to check if the player is going up or down to change the animations.
My idea is (vspeed = vertical speed):
If the vspeed > 0.01 (change to animation “going up”)
else if the vspeed = 0 (change to “in the air”)
else if the vspeed < -0.01 (change to “falling”)
I hope you understanding…
Well, please, help me @-@

(And sorry my english…)

//initial values
private float lastVertPosition = 0;
private bool inTheAir = false;

void update()
{
//compares vert position based on last frame
//If the player's vertical position has changed or they're in the air, then go to the sub if statements.
    if(lastVertPosition != this.transform.position.y || inTheAir)
    {
        if(lastVertPosition > this.transform.position.y)
        {
            inTheAir = false;
            //animation falling
        }
        else if(lastVertPosition < this.transform.position.y)
        {
           inTheAir = true;
           //animation jumping
        }
        else
        {
            //animation in the air(no change in vert position, but in the air.
        }
    }
    lastVertPosition = this.transform.position; //setting up for next frame
}

Hope this helps, just came up with it so it might have an error or two.
