Those are the different roles existing in the video games industry, more or less detailed. There can be more roles depending on the kind of industry and the size of the enterprise, more or less specialized. About deadlines, when there are certain processes times with a great length it is important to establish different deadlines to test and see how the video game is evolving since the beginning. The general deadlines are the following ones: first playable is a basic demo where the basic playability and arts are shown; alpha version is where the mechanics and scenarios are almost finished and it is often delivered 10 months before the definitive version. Then there is the code freeze, which is the definitive programmed game code, it is almost finished and the errors are corrected based on this code, possible errors that might happen are identified, and the process lasts over four months. This becomes the beta version, which is the game with definitive arts and mechanics but with some possible errors, and this beta is given to the testers so that they can play it and identify the possible errors in it. This beta version is usually delivered three months before the definitive video game version. The code release is the complete version, which is given to an external quality control and it is finished over one month before the definitive version. And finally, the gold master, which is the definitive version which will be commercialized either by downloading it or in DVD format. An important aspect in the video game development is what we call the 3Cs, which are very important and it is necessary to have those three Cs controlled in any moment of the game. The 3Cs stand for character, control and camera. We must know the characters' state in every moment of the game. Remember that this state allows us to define the character's behavior, its position, its cinematic, its attitude, and so we must have clear any moment the game is being played, which is each character's state and control this state in aim to control the characters. The second important thing is the control at a programming level, that means the program must be controlled every moment so that it won't suddenly crash or freeze, so that it won't collapse. It is not hard for this to happen, as we must take into account that a video game program is very complex, it has a lot of code lines, many modules, many interactions between them, and it is possible that it collapses or has certain programming problems. It is very important to avoid this control loss in any moment of the game. And finally the camera, we mustn't forget that the player, through this camera which is the screen he feels in the scene, as he sees the character's position and environment in 3D. It is very important to control where the camera is during every moment of the game, as the camera is the reference system which allows the player to see the scene in 3D. So the camera is an important point which must always be under control so that the player is able to know and see where its character is any moment and in aim to be able to interact with all its environment. In this example we will see a short recording of the game The Other Side, created by the Master students: it is a third person shooter and we will see an example of those camera, character control and game setting ideas. We will also see the background music effects, the sound effects which give the game a mystery situation, and so provide curiosity to the player playing the game. We can see the game is in third person, so it is important that the camera travels with the character, to control both the character and the scene view every moment. Now the character is reading some data... We can hear the character's steps and the tense background music Now the lights have changed, we have a different setting inside the same 3D scene but now it has a darker, more intriguing, more tense background. We control where our camera is in every moment, we know where our character is to avoid losing control of the interaction with the player. The character is under control all the time, how it behaves so that the player can control the character's movements and it responds to them. Either with reflections or with mirrors, it is important to have the character and enemies' positions under control. It is also important to see the interface to get to a maximum immersion level, give the less possible information about the health and the weapons' energy, so that the biggest part of the screen is dedicated to the scenario where we are playing. To sum up: a video game is composed by a great number of components. We've seen gameplay, we've seen engine, we've seen the AI part, the camera, the lighting, etc. In the gameplay part, the user's interface is very important, as well as the state of the video game, the internet connection if we want it to be online, so we have to put all those components together in aim to create this video game. It is a complex program with many code lines and so all those components must work correctly every moment. The video games development, as we have tried to show up through the roles, is a transversal activity as we have people working for art, conceptual art, sketchers, computational arts, 2D and 3D artists, etc. and on the other side we have a more technical profile: computing engineers, programmers, etc. So they have different languages, different ways to understanding. It is important that they have a common tongue to allow them understand each other, work in common, and sometimes we even find some egos between ones and the others when making an artistic and technological creation like a video game. There are many successful experiences in video games development but there can be problems during the production phase. And finally, the idea of developing a video game requires a huge coordination of all those profiles and the accomplishment of strict deadlines, as usually the release of a video game is determined by an important marketing campaign, in which the release date is very important. Not being able to launch the game in the established date can give economical problems to all the parts, so it is very important to accomplish the different hits and documents delivery deadlines, respect them so that the product is ready at its moment and do the right campaign. As the video games are becoming a cultural industry with a very important impact, especially when they are video games which already have an impact such as known sages, the public waits for this product's release. With this we finish this fourth module where we have talked on the many components of a video game and the existing roles in the industry. We hope you liked it. In this last slide we have some Youtube links with the different games we have seen during this module and an important document in which we have based our definition of the different roles in the video game industry. We really hope you liked this module.
