Once, during my work on the sadly never published game Reptoads – a round-based deterministic multiplayer cooperative card game, I got asked by different members of the art and design team: why can’t we have a visual scripting language such as Blueprints or Shader Graph for either the gameplay code or the visuals? My answer was always the same: we don’t have enough time to implement such a tool. This question, however, got stuck in my mind and I started searching for a “Lua” of the visual scripting languages just to find… nothing.
This paper investigates potential criteria to identify visual scripting languages as embeddable within the domain of game development. We explore the criteria of embeddability for scripting languages and use them as the base line for the study.
