rotation problem

as you can see i want my character to face the direction hes moving:

Code:

---

        if (Key.isDown(Key.UP)) {
                        h._rotation = 90;
                        h._y -= speed;
                }
                if (Key.isDown(Key.DOWN)) {
                        h._rotation = 270;
                        h._y += speed;
                }
                if (Key.isDown(Key.LEFT)) {
                        h._rotation = 0;
                        h._x -= speed;
                }
                if (Key.isDown(Key.RIGHT)) {
                        h._rotation = 180;
                        h._x += speed;
                }

---

but what would be the best method for ajusting the rotation to say 45 degrees when my character moves up and left at the same time?

Code:

---

if ((Key.isDown(Key.UP)) and (Key.isDown(Key.RIGHT))) ) {

    h._rotation = 45;
    h._y -= speed;
}

hmm it didnt work for me. maybe cuz im using flash 6?

here is the code:
rot_rad = _root.h._rotation * 3.141593 / 180;
if (Key.isDown(Key.UP)) {
_root.h._y += _global.speed*Math.cos(rot_rad);
_root.h._x -= _global.speed*Math.sin(rot_rad);
}
if (Key.isDown(Key.DOWN)) {
_root.h._y -= _global.speed*Math.cos(rot_rad);
_root.h._x += _global.speed*Math.sin(rot_rad);
}
if (Key.isDown(Key.LEFT)) {
_root.h._rotation -= _global.rot_speed
}
if (Key.isDown(Key.RIGHT)) {
_root.h._rotation += _global.rot_speed
}

thanks
