## Coding Golf - Broken Links



![Coding Golf - Broken Links](big_screenshot.png?raw=true "Coding Golf - Broken Links")



With planet Figadore ravaged by the Regolith virus, all sporting events have been cancelled. Determined to play a round of golf, Fred sneaks on to the "Coding Golf" island golfcourse where he works, to play a game.



Your mission is to help Fred get the lowest score possible on each hole so that he can win the "Broken Links" championship trophy.



Use the left/right cursor keys to rotate the direction the ball will be struck in, then select a golf club using the up/down arrows to adjust the range. Once you're happy, press SPACE/ENTER to start the swing meter. Then pressing SPACE/ENTER a second time will select a strike power (as a percentage), the meter will now move back towards 0. You then need to press SPACE/ENTER a final time as close to 0 as you can to prevent a hooked or sliced shot.



Alternatively you can use a mouse to play, use the scroll wheel will rotate the ball direction, then click for each step of the swing meter operation. You still need to use up/down cursors to change clubs.



A scoreboard is shown after each hole is completed. There are 18 holes in total. With added OS13k trophies.



# Stuff I managed to add

* 2D top down golf game

* Full screen, but landscape with target 720p (16:9 aspect ratio)

* Multi-layered canvas

* Reasonably realistic physics affecting ball movement (Wind / Gravity / Friction)

* Gamepad support

* Musical songs are ["The Chrysanthemum" by Scott Joplin](https://en.wikipedia.org/wiki/List_of_compositions_by_Scott_Joplin) (used in [BBC Micro](https://en.wikipedia.org/wiki/BBC_Micro) game Repton 2) and ["Black & White Rag" by George Botsford](https://en.wikipedia.org/wiki/Black_and_White_Rag) (used in BBC Micro game [Repton](https://en.wikipedia.org/wiki/Repton_(computer_game)))

* 8-bit tiny font (Repton inspired)

* Simple timelines

* [Wichmann-Hill pseudorandom number generator](https://en.wikipedia.org/wiki/Wichmann%E2%80%93Hill) inspired by [Sploosh Kaboom](https://www.youtube.com/watch?v=1hs451PfFzQ) minigame in [The Legend of Zelda: Wind Waker](https://en.wikipedia.org/wiki/The_Legend_of_Zelda:_The_Wind_Waker) on Nintendo GameCube

* Trophies via [OS13k](https://github.com/KilledByAPixel/OS13k)

* 3D trophy model creation using "[Solids of Revolution](https://en.wikipedia.org/wiki/Solid_of_revolution)" method (seen in Beebug magazine Vol.8 No.7 December 1989)



# Tools used

* [Ubuntu OS](https://www.ubuntu.com/)

* [vim](https://github.com/vim) text editor (also [gedit](https://github.com/GNOME/gedit) a bit)

* [meld](https://github.com/GNOME/meld) visual diff/merge

* [MeshLab](https://github.com/cnr-isti-vclab/meshlab) 3D model viewer

* [YUI Compressor](https://github.com/yui/yuicompressor) JS/CSS compressor

* [Google closure compiler](https://closure-compiler.appspot.com/home)

* [advzip](https://github.com/amadvance/advancecomp) (uses [7-Zip](https://sourceforge.net/projects/sevenzip/files/7-Zip/) deflate to compress further)



# Stuff I'd have done with more time

- [ ] Fix gamepad support

- [ ] Play the course in 3D rather than top-down

- [ ] Investigate using WebGL for rendering

- [ ] Choose player avatar before starting
