# LD39 - Soaring

This is a Ludum Dare 39 game jam entry.

## Game summary

  * rules

    * 1HP, must pick fuel periodically (in tough spots) and may pick coins

    * constant player movement in XX

    * vertical impulses to keep ship above ground

  * items

    * gas (required to keep gas level above 0 else game over)

    * coins (best effort. catching all in a level unlocks full level completion)

    * power ups

  * score

    * survived game time and picked coins

  * obstacles

    * static platforms

    * moving platforms (recurring movement/rotation)

      * gates opening/closing

      * rotating elements

  * item placement

    * items can be static, but also tied to platforms and or with assigned paths (if so, one must grasp them fast otherwise too hard)

  * enemies (not sure these are necessary given the game constraints, only relevant if we can affect them in some way)

    * classic patrolling movement around point

    * sine wave movement à là r-type

  * power ups

    * invincible

    * speed up/down XX speed

    * power up centers camera ahead of player, allowing to see more of the level

    * rotate the camera (harder to reason about)

    * kill visible enemies

    * kill destructible obstacles (are these any of these?)

    * invert YY gravity

  * game appearance / vibe

    * average/poor art, best effort (most likely)

    * crude solids with vibrant colors (geometry dash)

    * dramatic with normal lights

  * nice to haves

    * decent sprites (may drop compo to jam and use artwork from elsewhere such as [kenney](https://kenney.nl/assets))

    * music (either: none, use free licensed, from a friend - therefore jam)

    * sfx (might do with simple generators since the theme is simple enough)

    * lighting as an obstacle (would require sprites to have )

## Supported browsers

* tested / targetted

  * android chrome

  * mobile safari (iphone/ipad)

* best effort

  * chrome, safari

## Tech stack

* browser and javascript

* 2D gfx with [pixi](http://www.pixijs.com/)

* collision detection with [bump](https://github.com/kittykatattack/bump)

* audio with [howler](https://howlerjs.com/) [docs](https://github.com/goldfire/howler.js#documentation)

## Artwork stack

* graphics

  * used [blender3D](https://www.blender.org/), [inkscape](https://inkscape.org/),  [gimp](https://www.gimp.org/) and generated some procedural textures with [tg](http://blackpawn.com/dev/tg.html)

  * the background sky and a couple of pill sprites came up from kenney.nl, didn't manage to replace those in time :P

* sfx and music

## some references

## TODO list

* ~~brainstorm~~

* ~~set up basic engine~~

  * ~~renders sprites~~

  * ~~touch support~~

  * ~~music and sfx playback~~

  * ~~level loading~~

  * ~~keep aspect ratio and viewport independent of screen~~

* implement game rules

  * ~~xx constant movement~~

  * ~~impulse~~

  * ~~texture loading~~

  * ~~basic box collision support~~

  * ~~pick up coin~~

  * ~~gas tank logic~~

* ~~tiling bg~~

* ~~animated items (coins etc)~~

* ~~start screen > play > game over | pause states~~

* ~~compress audio to howler compatible formats~~

* ~~request fs and avoid double events~~

* ~~reset time on game over~~

* ~~level transition~~

* ~~highscores (displayed on game over)~~

* ~~pitch ship according to y speed (requires improved collision det)~~

* ~~graphics made with blender, tg (procedural) and gimp~~

* ~~prepare publish~~

MAYBE

* animate title screen

* toggle sfx and audio (persist to LS) -> done. still no way of toggling

* google analytics, if time permits

DOUBT IT

* review cleanup (ex: sprite.destroy())

* implement and add power-ups

* particle effects

* additional backgrounds with different parallax?
