Generation of content for games is one of the major bottlenecks in terms of the effort required and the resources to be committed. A typical AAA game contains tens of thousands of sound files as audio assets which include spoken dialogue as well as sound effects. Procedural content generation (PCG) provides a cost effective alternative to recording these sounds in the studio or in the field. While some sound effects can be recorded fairly easily given the necessary time, effort, and resources, some others such as gunshot sounds are not easy to record. Since many games and simulations incorporate firearms, parametric sound synthesis which is essentially a PCG technique can be used to alleviate the need to record gunshot sounds. This chapter describes a physically-motivated parametric gunshot sound synthesis model. The model is based on a deconstruction of the gunshot sound event into its constituent parts and uses parameters such as the barrel length, bullet type, and muzzle velocity to synthesise the sounds of different firearms. A subjective evaluation which investigates the perceptual relevance of the proposed model is also presented.

Developing a Space Syntax-Based Evaluation Method for Procedurally Generated Game Levels Bıyık, Emin Alp; Sürer, Elif (2020-12-01) Procedural content generation (PCG) has been an essential catalyzer in the last decade with its efficiency in creating game elements such as textures, game levels, and maps. Despite being successfully applied in various studies, new reliable evaluation tools are still needed to assess the quality of the generated game content. One example limitation of procedurally generated game worlds is the lacking spatial configuration. To address this issue, in this study, an assessment method was developed to evaluate...
Multimedia Information Retrieval Using Fuzzy Cluster-Based Model Learning Sattari, Saeid; Yazıcı, Adnan (2017-07-12) Multimedia data, particularly digital videos, which contain various modalities (visual, audio, and text) are complex and time consuming to model, process, and retrieve. Therefore, efficient methods are required for retrieval of such complex data. In this paper, we propose a multimodal query level fusion approach using a fuzzy cluster-based learning method to improve the retrieval performance of multimedia data. Experimental results on a real dataset demonstrate that employing fuzzy clustering achieves notab...
Level generation using genetic algorithms and difficulty testing using reinforcement learning in match-3 game Dukkancı, Samet Alp; Alpaslan, Ferda Nur; Department of Computer Engineering (2021-9) The gaming industry is an enormous one that includes game development, art, and marketing. It has grown faster in recent years, especially in the mobile gaming area. Competition in mobile gaming increased in such a way that it brings us some challenges like quick prototyping, automation, minimum viable products, and so on. Level generation is the most important issue in the development period because unique and well-adjusted difficulty for a level is generally tested by humans many times for one level to as...
Context based dynamic content generation, introducing a new approach and a framework Özdemir, Burkay; İşler, Veysi; Department of Modeling and Simulation (2015) Game Industry is growing every day with thousands of games are being released each month. Although game development tools are constantly become more easy to use, accessible and carry most of the workload of developers, serving fresh content is still a big issue for developers. Procedural Content Generation (PCG) is used as an alternative method to providing content manually. Despite its main purposes like reducing the memory usage are fading away with the recent developments, it has a huge potential to crea...
Agent learning in fully observable, continuous and real-time game environments Baykal, Ömer; Alpaslan, Ferda Nur; Department of Computer Engineering (2016) Game industry has become one of the sectors that commonly use artificial intelli- gence. Today, most of the game environments need and include artificial intelligence agents to offer more challenging and entertaining experience. Development processes and the quality of artificial intelligence agents are the most important concerns in this area. Since it becomes harder to develop good agents as games become more com- plex, machine learning methods have started to be used in some notable games to shorten this...
