  • Method Details

    • getIdentifier

      Component.Identifier getIdentifier()
      Returns the identifier of the axis.

    • isRelative

      boolean isRelative()
      Returns true if data returned from poll is relative to the last call, or false if data is absolute.

    • isAnalog

      boolean isAnalog()
      Returns whether or not the axis is analog, or false if it is digital.

    • getDeadZone

      float getDeadZone()
      Returns the suggested dead zone for this axis. Dead zone is the amount polled data can vary before considered a significant change in value. An application can safely ignore changes less than this value in the positive or negative direction.

    • getPollData

      float getPollData()
      Returns the data from the last time the control has been polled. If this axis is a button, the value returned will be either 0.0f or 1.0f. If this axis is normalized, the value returned will be between -1.0f and 1.0f.
