Using the glory of regex, we can scrape any Lua script files that a map includes and locate calls to the UserInterface.Translate method. We can then treat them in the same way as C# fields marked with a TranslationReferenceAttribute. This allows the lint check to validate the translation invoked in the .lua script has a matching entry in the translation .ftl files, with all the required arguments (if any).
We can also locate any calls to AddPrimaryObjective or AddSecondaryObjective defined by the utils.lua script, which also accept translation keys.
The are a couple of restrictions:
- When linting the map, we don't check for keys in the ftl file that are unused. This is because the linter doesn't load all the keys when checking maps.
- In order to validate translation arguments with the regex, we require the Lua script to pass the table of arguments inline at the callsite. If it does not, we raise a warning so the user can adjust the code.
Reduces size used for png files from 19,034,446 bytes to 13,305,798 bytes in total. The smaller files also improve loading times as the zlib decoder has less bytes to schlep through.
The PNG decoder shipped with OpenRA only supports a bit depth of 8 for images with a palette, so must must ensure that other depths (1,2 or 4) are not used.
zopfilpng is used for compression with the following command line:
'zopflipng.exe --keepcolortype -y -m image.png image.png'
The keepcolortype flag ensures the bit depth is not changed.
PlayerReference colors in D2k missions only affect chat text and minimap colors because actors use specific palette colors.
So using the colors from the original game's minimap.
