A downloadable asset pack

Created to accompany a tutorial for issue 36 of Wireframe magazine, this downloadable demo includes a Twine game file that you can load up to look at, play with and copy bits out of to your heart's content.

Note that this is not a complete game. It's a learning aid consisting of just a handful of screens.

What works:

  • video playback
  • video and question div positioning
  • a flag to activate a hidden question

Because this tutorial replicates a sequence from Sierra's 1995 FMV game The Beast Within: A Gabriel Knight Mystery, the video files are placeholders for teaching purposes. You can buy Gabriel Knight 2 from GOG and Steam.

If you want the authentic Gabriel Knight experience, you'll need to copy, convert, upscale and rename the following videos from your Gabriel Knight 2/GK2/MOVIES directory:

490.VMD becomes Klingmann.mp4
500.VMD becomes mammal_division.mp4
510.VMD becomes interested_in_wolves.mp4
520.VM becomes, what_kind_of_wolf_research.mp4
540.VMD becomes missing_wolves.mp4

I did the VMD to MP4 conversion in a terminal window using a simple bash script to invoke ffmpeg, thus:

for i in *.VMD; do ffmpeg -y -i "$i" -vf scale=616:334 "${i%.*}.mp4"; done

This should work on any machine running Linux or macOS and also scales them up to double their original size.

You can then manually rename the files as indicated above.

Created with Twine 2.3.5, Harlowe 3.1.0
