Edelweiss

Open source webGL game made with three.js

Play online here : http://edelweiss.32x.io

How it works

Custom physics engine
The game works with a simplistic physics engine based on axis-aligned bounding box collision detection. All the physic objects in this game are either boxes or axis-aligned square tiles. Find the code here.

Custom map editor
The information about the physical map is contained in an JSON called sceneGraph that the game loads on statup. I created this file using a custom map editor, that I coding for the sole purpose of making this game. Find the code here in a separate repository.

Manual camera positioning
Moving the camera to support a 3D platformer game is a challenge, that I had to face on my own since I used a custom physics engine. Find the code here.

Automatic optimization
The game is playable from mid-range mobile to high-range desktop. To support this adaptability, the game adapt itself to the device capability at runtime. Find the code here

Runtime assets loading
This game is light, but I still wanted to optimize loading time by loading map tiles at runtime. Find the code here

Contributing

If you fancy extending the game, I'm up to merge your work, as I already did with Makc multiplayer and debug mods.

If you feel more like correcting a few bugs here and there, here is a wishlist :

fix hero climb-down-right animation
if the player dies, got the first edelweiss, but didn't save their progress yet, respawn them in front of the first cave instead of the starting point of the game
add movement sounds (climbing, footstep...)
add powerup sounds
add tweening for the reduction of the stamina bar
add dust animation when player fall because of a fall-tile
fix issue of joystick position with Galaxy S9+ (chrome for android)

Big thanks to Makc for contributing !

The multiplayer feature
The debug and live-map-editing features, that you can access by typing these commands into your browser's console while playing the game :

atlas.debug() // show the physical assets used for collision while you play, and UI for editing the map
atlas.player.showHelpers() // show a helper for the player's direction
controler.permissions.airborne // cheat code for flying freely with the glider
