About this project
What does StarTweaker add?
The main goal was to add features that galaxyspace had on one planet that I really liked and it was the fog system so I knew that I had to create a mod that lets you override any dimension.
The mod is gui based and the changes can be seen live so no need to restart the game.
To open the gui run /startweaker in the chat
Current features :
-Custom fog system
-Custom cloud system
-Custom heat distortion (mirage) system
-Custom atmospheric pressure system
-Custom weather system (acid rains and changing the way the rain looks like)
- Custom penalties for not having an oxygen supply (for galacticraft)
Future features
- Weather systems from other mods like galaxyspace
- Fixing solar panels having weird boosts if on planets made by starmaker
- Fog appearing at one time and dissapearing at another
- Solar storms that jam your machines for a few seconds
- Custom Audio distortion (for galacticraft)
- Custom world gen (maybe)
