- ** $VER: VerticalScroll.fred 1.2.0 (23.10.93)
- **
- ** This program can be run from an InvokeADPro list to rotate the current
- ** frame by the previously defined amount.
- **
- ** Clips Imported:
- ** FREDNumberOfFrames - Total frames selected
- ** FREDYPosition - Current Y Position of the frame
- ** FREDYIncrement - Y Increment per frame
- ** FREDYDirection - ~0 if movement is to the right
- ** 0 if to the left
- ** FREDRollWrap - ~0 if image should wrap around
- ** 0 if not
- **
- ** Clips Exported:
- ** FREDYPosition - Current Y Position of the frame
- **
- ** NOTE: Clip names are case sensitive.
- **
- ** This script requires FRED v1.4.0 (or higher) to run. Also required is
- ** ADPro v2.5.0 (or higher).
