Until there is a release you can download the repository, and paste the contents of the _MOD\ folder into your Skynations-Server root directory. After enabling the Mod in your Server Settings.xml (example provided) you can start your server up and use the new Blocks. Until further notice, this Mod is NOT production ready!

At the moment the goal is to provide more decorative Blocks, preferably ones that can be crafted from existing materials within the game. Blocks which require scripting to properly work because they have a mechanic, or Blocks and Items which would likely be found in a new Biome are, for now, out of the scope of this Mod, but will be listed here regardles, for future reference.

• simple Blocks with a shape that already exists in the game (cube, wedges, railings, ...)
• no mechanics (scripts) needed to use them

= simple craft and place blocks, nice to look at and used for decoration

• all others

This are mostly blocks that either need to have a new shape/mesh made for them and/or which need a script to work properly within the game world and/or need new Biomes.

Set 1 takes priority for now as its easy to implement and almost anyone can help with that. Its as easy as filling out a form (Tiles.xml and Blocks.xml) and drawing a picture (creating the texture).

Pick any block you want to see in the game and provide files for it in a pull request. You don't have to provide everything needed to implement a new block, its fine if you only submit a texture, the .xml files or a script, this is an open project and maybe someone else helps providing the other parts needed. Do not submit a pull request that changes anything within the _MOD\ folder, it will not be accepted. Create a new folder for your changes within Contributions\ and put your files in there. The folder structure therein should ideally mirror the one over in _MOD\. Your contribution will be reviewed, open for discussion and, if needed, subject to change (e.g. weight and cost of blocks have to be balanced in the grand scheme of the game etc.). Later it will be copied over into the _MOD\ folder by a maintainer and released.

For further information about modding in Sky Nations, go to Sky Nations Wiki.
Do not forget to check out the Tiles.xml in the GameData folder, there you can find the full list of Blocks already in the game and their properties, so you get an idea about the attributes you can use for your custom Blocks. Additionally you can download the Sky Nations Default Block Textures here: Sky Nations Forum
