Unity: Can we not change Animator State inside Update?

Question

void Update () {

        if (goright == true) {
            rig.velocity = new Vector2 (m.movespeed, rig.velocity.y);
            m.anim.SetInteger ("State", 1); 
        }

        if (goleft == true) {
            rig.velocity = new Vector2 (-m.movespeed, rig.velocity.y);
            m.anim.SetInteger ("State", 1);
        }
    }

    public void ondownMoveLeft(){

        goleft = true;
    }

    public void ondownMoveRight(){

        goright = true;
    }

    public void onupMoveLeft(){

        m.anim.SetInteger ("State", 0);
        goleft = false;
    }

    public void onupMoveRight(){

        m.anim.SetInteger ("State", 0);
        goright = false;
    }

i am using this code to move my character using UI buttons with the help of Event Triggers. i set it to change the animation from idle to running or from State 0 to 1 when the player moves and it does works that way but the problem is once it goes into State 1 it never comes back to State 0 but it should since i am setting the State back to 0 when the OnPointerUp trigger gets activated. am i missing something?

OnPointerDown is calling its respective ondown method and OnPointerUp is calling its respective onup method. for eg, when you press the left button it calls OnPointerDown which is set to call the method ondownMoveLeft.

i also checked with Debug.Log and everything is being executed but still the animation State is not changing.

Since you use Mecanim you need to have two transitions, one from state 0 to state 1 and another from state 1 to state 0.
