Year 1 - Unit 20 – Computer Game Platforms & Technology – Software Technology

Unit 20 – Computer Game Platforms & Technology – Software Technology

Task 1 - Operating System (OS):

What is an operating system?
Software that supports a computers basic functions, these include managing peripherals and plan tasks. They perform basic tasks including acknowledging keyboard and mouse input, sending outputted information to the monitor, taking note of files on the disk and controlling peripherals like printers. 

Platform dependency and independency:


Platform Dependency
Platform Independency
Software needs a certain type of hardware and/or operating system to work.
Software that can run on most hardware and/or operating system to work.

Nothing is perfectly plat form independent as everything still need some sort of hardware.

Functions:
                 Microphone - Sends an input of sound which can be recognised and written as text or used                                         as a voice command etc. It can also be recorded and fed back later on.
                 Motion Control/Detect - Allows the user to interact with the system through body                                                                        movement. Its usually through real world gestures. A good                                                                      example is the Nintendo Wii and Playstation Move, they both                                                                require a device a handheld controller for motion control, they do                                                          however work very differently. The Playstation Camera and                                                                    Kinect work by using a camera to sense movement.
              VR support - Use of Computer Technology to create a simulated environment, you are                                               immersed into a different world and can interact with it.
              Controller - Used to input information (usually to control object or characters in a game.                                         They can be classed as keyboards, mouses, gamepads and joysticks etc.
              Touchscreen/pad - An area that allows the user to interact with a device by touching areas on                                             a screen.
              Remote play - Allows the PS3 and PS4 to transmit audio and visuals to a PSP or PSV.

Task 2

What is a device driver?

A program that controls a particular device attached to the computer, they are for displays, printers and CD-ROM readers etc. When you buy an OS many device drivers are built in however, if later on you decide to buy a new device that the OS did not see coming then you would have to install a new driver. They convert general input/output instructions of the OS to a message that the device can actually understand. 

Application software:

Interpreted Languages -
Does not need to be compiled first so its not needed to be turned into machine code runs and it runs on the fly. Runs more slowly than compiled as it has to actively perform the step of  changing the code into the device can handle on the fly. You can change the program when you open it and its ready to go.
Examples:
                Java - Was designed to look and feel like C++ but is much simpler to use. It can be used to                              create complete applications that can run on a single computer or be assigned among                            servers and clients in a network. It is a popular choice for applications on Android                                smartphones. Games created in Java: Roboforge by Liquid Edge Games, Runescape                            by Jagex and Tom Clancy's Politika by Red Storm Entertainment.
                Python - It has a design philosophy which emphasizes the readability of code and a syntax                                 which allows any programmers to show concepts in much less code than what is                                   possible in C++ or Java. Games created in Python: EVE Online by CCP Games,                                   Frets on Fire by Unreal Voodoo and the original Galcon by Imitation Pickles.
               C# - A programming language from Microsoft that aims to merge the computing power of                          C++ with the ease of programming in Visual Basic. It's features are similar to those in                          Java. Games created in C#: ?

Compiled Languages -
It must be compiled before it is run so it is worked out on the fly. However it runs faster than Interpreted code. While it is being compiled it is checked for errors, these are then reported and can be fixed before re-compiling. The compiling converts the code into machine code/binary. A C program that was compiled on a Windows computer cannot then be run on a Linux computer. You would have to compile the program using a C compiler on a Linux computer.

               C - It is ideal for developing filmware or portable applications. It was first intended for                             writing system software and was developed for the Unix Operating System in the early                         1970's at Bell Labs by Dennie Ritchie. Games created in C: ?
               C++ - Developed by Bjarne Stroustrup, it is an OOP (Object Orientated Programming)                                  language and in an expanded C language. It is therefore possible to code C++ in a C                            style. It is an effective example of a hybrid language as it can be coded in either.                                  Games created in C++: Doom III by id Software, Counter Strike by Valve L.L.C. and                          World of Warcraft by Blizzard Entertainment.
Game Engines -
A Game Engine is a type software that creates source code and makes elements that begin another process, letting real-time maintenance of software requirements. Its made for the creation and development of video games, this includes consoles, smartphones and PCs.

              GameMaker - It has a built in language called GML (Game Maker Language). Games                                                created in Game Maker: ORBIT by 4Bit Games, Hyper Light Drifter by Heart                                      Machine and Defenders of Ekron by Vitro Games.
              Unreal - It uses the programming language of C++. Games created in Game Maker: Gears of                             War 4 by The Coalition, Tekken 7 by Bandai Namco Studios and We Happy Few by                             Compulsion Games.
              Unity - It is programmed in C# and the development is done with your choice of C#, Boo or                           a dialect of JavaScript. Games created in Unity: Kerbal Space Program by Squad,                                 Firewatch by Campo Santo and SUPERHOT by Superhot Team.

Graphical API:

DirectX - 

It is designed by Microsoft (only available on Microsoft products e.g Windows and Xbox) to allow straight access to hardware and it contains a range of APIs (Application Programming Interfaces) for multimedia and video applications along with video games. It allows access to the advanced features of high-performance hardware like 3-D graphics acceleration chips and sound cards. This also includes 2-D graphics acceleration, support for input devices and control of sound mixing and input.

Open GL -

Open Graphics Library is a cross-language, cross-platform API and is used to render 2D and 3D vector graphics. It interacts with the GPU to get hardware-accelerated rendering. Very similar to DirectX but allowed on Microsoft platforms like Playstation, Apple Mac and Linux. There are modified versions on Android and IOS machines.
