List of changes

• skybox replaced with a part of the Cat’s Paw Nebula
• added the following planets – distances not to scale, diameters inspired by Create a Solar System Scale Model With Spreadsheets
  • Mercury
  • Venus
  • Mars
  • Jupiter
  • Saturn
  • Uranus
  • Neptune
  • Pluto (technically a dwarf planet (- ‿ ◦) )
• changed sounds for some of the planets, taken from NASA site and SoundCloud
  • Earth
  • Mars
  • Jupiter
  • Saturn
  • Pluto
• Sun sound turned off, so it’s easier to keep track of the sound of the planets
• every planet leaves a colored trail to make it easier to follow, mimicking the effect used on Eyes on the Solar System
  • changed background color of the minimap to make trails easy to see
• WebGL build is compatible with version 1 and 2 to ease peer reviewing – to achieve this changed color space to Gamma and Enconding Quality to Normal

Properly zipping macOS builds under Windows

For the final bundle to run properly on macOS, the executable under Contents/MacOS needs to have the executable permission set – otherwise you will get a generic error stating that “The application macOS cannot be opened”. Executable permissions are not typically set if the application is packaged as a zip file under Windows, because 1) the file systems supported by this OS (FAT, NTFS) do not have this concept and 2) as a result archiving programs will not infer that when creating the zip.

These approaches will ensure the final bundle will run properly:

Copy to an USB key

Transfer the final .app to an usb key with FAT32/exFAT filesystem, and copy that to the target system – this way all the files in the bundle will be treated with as having rwxrwxrwx permissions

Package the application under WSL

Example command

cd /mnt/c/<path to Builds folder> zip -r SolarSystem.app.zip SolarSystem.app

Similarly to the previous solution, WSL will infer rwxrwxrwx permissions for files on native volumes

Resort to a custom script to create the final zip manually setting executable permissions for the executable

This is a bit overkill in the context of this project, but it makes more sense in a build pipeline.

Sample approaches to solve this can be found in this support program for Galaxy Forces and in this Github Gist – the latter requires to also set info.create_system = 3 for the executable bit to set correctly for the owner.
