The main purpose of this thesis was to create the proof of concept of a dialogue system of a videogame. The system would consist of a dialogue graph, a word search to allow the player to interact with a non-player character and some fuzzy logic variables to control the state of the character.
The system was created using the game engine Unity with an Ink-unity integration plugin, the Inky editor and some external C# libraries. It assesses the feasibility of using word embeddings, obtained with a pretrained unsupervised learning algorithm; and semantic similarity, obtained through cosine similarity, to match words in a word search.
The results showed a low suitability of the word embeddings model and semantic similarity used due to having a low precision for the required task. In contrast, the dialogue graph and the fuzzy logic state variables have been shown to achieve the desired outcome.
