Musical Interlude

The complete title of the novel I’m working with is The Life and Opinions of the Tomcat Murr together with a Fragmentary Biography of Kapellmeister Johannes Kreisler on Random Sheets of Waste Paper. Really long titles were a thing back in the day. As the full version of the title indicates, there are actually two plot lines developed in the text, one about Tomcat Murr and the other about Johannes Kreisler, who is a musician (Kapellmeister = ‘musical director’). Because this is his profession and because music plays a central role in the novel, it seems fitting that virtual-Kreisler should have an instrument. In the novel, he has a “guitar” made in 1532, which is interesting, since the history of the development of the guitar suggests that it may be a bit of an anachronism. There most certainly were hollow, stringed instruments around at that time, but the most popular one was called a vihuela. I have taken the artistic license to model my virtual instrument after the ‘baroque guitar,’ which was developed in the following century; this comes close to the age of the fictional guitar and preserves the detail that it significantly predates the period in which the novel takes place. In addition, the aesthetics of the baroque guitar – its long, sleek shape and sophisticated design – seemed to fit Kreisler’s serious commitment to his art as well as the Romantic atmosphere of the novel.

I modeled the guitar in Blender using the image that would later be mapped onto it as a guide.

Then, I made a UV map and fitted it to the texture images, which I had assembled in GIMP. Here is the completed mesh after being imported into Unity:

Humongous guitar sticking out of a building … it must be downtown Nashville

Interesting things happen when you first drag in a new mesh.

Please do not strum actual guitars with a wrench.

The image of the guitar body is from a photo of a reproduction made by Sebastian Nunez & Veronica Estevez in 2004. I found this lovely image on www.luteduo.com and they kindly allowed me to use it. The site has several mp3 samples that give an idea of what a baroque guitar sounds like.

Emergent Houses / Emergent Gameplay

The landscape in Sieghartsweiler is still undergoing some modifications, and will probably continue to do so, but the basics are mostly taken care of. Over the past couple of weeks, the houses have been my first priority. Due to the limited availability of suitable pre-made object meshes in the Asset Store, I realized that I would need to be able to make my own. Thus I needed to learn how to do 3D modeling in Blender. (There are other options, but Blender has the decisive advantage of being free.) After a series of YouTube tutorials, a good deal of experimentation, and transient bouts of frustration, I managed to build and import several meshes that will become the houses.

Here are my house meshes in Blender, before importing to Unity. I built them all in the same file so that the scale would match exactly, but then saved each piece in a separate file in order to simplify the importing and texturing processes.

The house meshes are modular so that I can vary them in Unity by adding different textures and different numbers of storeys. So far, I have only placed a couple in the landscape as an initial test. One extremely helpful thing that I did find in the Asset Store was an “18th century doors and windows” pack. I stuck one of each onto one of my houses, again just as a test – these required a fair amount of scale adjustment in order to be human-sized.

Because of their modularity, it's easy to vary the color of the stucco. The guy in the yellow hard hat is for scale testing purposes, not a stray member of the Village People.

I’m a little concerned that my birch trees aren’t rendering in very much detail in the background – have my models got too many polygons already? Are my specular textures too complex? I guess we’ll find out as I continue to build.

As I inch closer to the point at which I will be making more decisions about gameplay mechanics and fewer about appearances, I have been pondering the issue of emergent gameplay, particularly as formulated by the ludologist Jesper Juul:

[…] most computer games are the combination of two different ways of presenting the player with a challenge, one which I will term emergence (simple rules combining, leading to variation) and one of progression (serially introduced challenges).(1)

As I develop quests for this game adaptation, I will have to consider how to balance these forms of interaction. The implementation of these gameplay dynamics will have a significant impact on what the players can potentially learn through the game. It would seem that progressive play gives the game designer much more control over the narrative arc of the game. As theorists have widely noted, emergent gameplay is often distinctly separate from the narrative elements of video games. Narrative is often presented through cut screens or other devices which offer little or no player interactivity and occur “in between” episodes of gameplay, such as at the beginning or end of levels or other markers of progress. On the other hand, one of the most appealing aspects of games is their very interactivity, such that too-severe limits on emergence could compromise the effectiveness of a game. I have been wondering about possibilities for integrating both emergent and progressive elements: Would it be better? In what situations? Is it even possible?

This is something I’ll have to keep thinking about, but for now, it’s time to start building some humanoid meshes!
