Programming Fundamentals
•
What is computer programming?
–
The process of writing, testing and maintaining a computer program
for accomplishing a specific task.
•
•
What is a computer program?
–
A sequence of instructions that automate the process of performing a
task for solving a specific problem.
How to write a computer program?
–
A computer program is written using a programming language.
Programming Fundamentals
•
•
What is a programming language?
–
A programming language is a vocabulary and set of grammatical rules
for instructing a computer to perform specific tasks.
–
Examples of programming languages: C, C++, C#, Java, JavaScript,
HTML, PHP, Python, Lua, Processing, Ruby, Objective-C, Prolog, Go, …
What is the best programming language?
–
There is no "best programming language". It depends on the goals of
the application, platform, programmer’s skills, etc.

Evaluation
•
Project deliveries:
–
–
1st delivery: game specification
•
No evaluation for Programming Fundamentals
2nd delivery: working prototype
•
General code organization and indentation, appropriate use of variables,
well-structured loops, appropriate use of arrays, functions and correct
physics simulation
–
3rd delivery: final version
•
Same as the 2nd delivery + overall code complexity and game experience
+ individual discussion + programming report
Lua Programming Language
•
Lua is a powerful, fast, lightweight, embeddable,
free and open-source scripting language designed
for general purposes.
•
•
In video game development, Lua is one of the most
popular scripting language for game programming.
Lua was developed by a team of researchers at
PUC-Rio (Pontifical Catholic University of Rio de
Janeiro) in Brazil.
–
Currently, PUC-Rio has an entire laboratory (LabLua)
dedicated for the development and maintenance of the
Lua language.
Lua Programming Language
•
Games that use Lua as scripting language:
–
–
–
–
–
–
–
Angry Birds
Civilization V
Far Cry
Grim Fandango
Ragnarok
Dota 2
World of Warcraft
Löve 2D Framework
•
LÖVE is a framework to create 2D games in Lua.
–
It comprises a library of functions to draw visual objects, control user
interaction, simulate physics, play audio, and everything else a game
needs.
–
It's free, open-source and multiplatform (Windows, Linux, Mac OS,
Android, iOS, Web Browsers).
Software

Example of Game (Lua + Löve2D)
...
function love.draw()
for i = 1, numStars do
love.graphics.setColor(255 - stars[i].speed,
2
1
55 - stars[i].speed/2,
50, stars[i].speed*0.9)
love.graphics.draw(star_image, stars[i].x,
stars[i].y, 0, stars[i].speed/255 + 0.55)
end
love.graphics.setColor(255, 255, 255)
if spaceship_isBoosted == false then
love.graphics.draw(spaceship_image_normal,
spaceship_x, spaceship_y)
else
love.graphics.draw(spaceship_image_boosted,
spaceship_x, spaceship_y)
end
local totalLaserBeams = table.getn(lasers)
for i = 1, totalLaserBeams do
love.graphics.draw(laser_image, lasers[i].x,
lasers[i].y)
end
end
