Input.GetAxisRaw

Descripción

Devuelve un valor del eje virtual identificado por axisName sin un filtro de suavizado aplicado.

The value will be in the range -1...1 for keyboard and joystick input. Since input is not smoothed, keyboard input will always be either -1, 0 or 1. This is useful if you want to do all smoothing of keyboard input processing yourself.
