TINS 2021

Content

Introduction

Welcome to Qbitter!

Qbitter is a game loosly based on a work "LW305 Kringloop" of M.C. Escher where a gnome runs down a stairs and morphs into its 2D abstract shape. The game also lends ideas from Q*Bert, a game from the eighties that was itself based on the works of M.C. Escher. In the game you (represented as a gnome) have to collect stars while trying to avoid enemies (hexagons). Every level has increasing difficulty.

Controls:

W: move up (left) cube A: move down (left) cube S: move down (right) cube D: move up (right) cube

Additional Rules

Implementation

genre rule #143

This rule has been omitted (too subjective) by applying the bonus rule. There is two elements that could be considered funny though:

  • The gnome (player) is an character that is absurdly placed in this world, both style (hand drawn vs geometric) and color (gray vs colorful) are opposites of each other.
  • In the credits my own libraries are blatantly mentioned first (yes I know, it could be considered arrogance or is it humorous as well?).

artistical rule #147 The game is based on a work of M.C. Escher "LW305 Kringloop" and it shows in different ways:

  • The isometric cubes of the game try to mimic the style.
  • The gnome featured as player is a loose interpretation of the gnome drawn by M.C. Escher.
  • Geometric figures are used as game elements (stars, hearts, enemies).
    • They are all based on a formula applied on a polar coordinate system (also the heart but this one isn't repeated).

artistical rule #94

In the credits some of the libraries I wrote (and used) are promoted (Developed using geom, zntg and allg5). To be sure that people notice this I put them on top of the list of credits.

technical rule #113

The main grid is made of cubes (faux 3D) that are regular hexagons in 2D. Additionaly the enemies of the player are made of wobbly hexagons.

bonus rule #13

Some functionality of the root package (tins2021) is unit tested (coverage is at time of writing 17% of the statements). You can find the tests in the files ending on _test.go (e.g. level_test.go).

Definition

Genre requirement

**** There will be 1 genre rule

genre rule #143

Humoristic/Funny. Make the player laugh out loud at least once by funny situations, dialogue, or anything else in your game.

Comments: If you need inspiriation take a look at this list of 27 funniest video games of all time (Which includes some of my personal favorites, like monkey island or THHGTTG text adventure).

Artistic requirements

**** There will be 2 artistical rules

artistical rule #147

Inspired by MC Escher

Comments: M.C. Escher created math-inspired graphical art. He created well known artworks that use impossible objects, symmetry and tesselations. One might say he was the very first creative coder. All his works can be browsed on this online gallery.

artistical rule #94

The game should contain a plug for another program or thing you made.

Comments: It's not uncommon for a game to contain ads for other games by the same publisher. But you can get creative with it. Take for example Kings quest II. In that game you can find a complete trailer for Space Quest hidden as an easter egg.

Technical requirement

**** There will be 1 technical rule

technical rule #113

Hexagonal - something in the game must be hexagonal

Comments: Hexagons are the bestagons.

Bonus rule

**** There will be 1 bonus rule

bonus rule #13

Test of Might - you may skip another rule if your code contains automated test coverage (integration or unit tests).

Comments: You may use this as an escape clause to remove one of the other rules. Your automated test code should be included with your submission. For clarity, explain whether you applied this rule, and which rule you skipped, in the README of your game.

Building

Prerequisites:

  • SDL 2.0 (SDL2, SDL2_image, SDL2_ttf and SDL2_gfx development libraries are required; for more information).
  • Go 1.12 or later.
  • GCC or a compatible compiler.
  • Git.

Note: the SDL 2.0 dependency can be replaced with Allegro 5 as well.

With all prequisites installed you can run:

go get -u opslag.de/schobers/tins2021/cmd/tins2021

This will create the binary $HOME/go/bin/tins2021. Additionally you can embed the resources and build a static release with the following commands (this assumes $HOME/go/bin is available in the PATH):

go generate opslag.de/schobers/tins2021/cmd/tins2021
go install -tags static -ldflags "-s -w" opslag.de/schobers/tins2021/cmd/tins2021

Using Allegro

If you want to use the Allegro backend you can add the build tag allegro to the go install command. E.g.:

go get -u opslag.de/schobers/allg5
go install -tags static,allegro -ldflags "-s -w" opslag.de/schobers/tins2021/cmd/tins2021

In this case the SDL 2.0 prerequisite is replaced by Allegro 5.2 (development libraries must be available for your C compiler).

Command line interface

You can extract all resources embedded in the executable by running it from the command line with the --extract flag. The resources will be extract in the current working directory. Note that the game will use the resources on disk first if they are available.
