The answer is "No" to all questions. Only things like unit descriptions, unit stats, unit logic can be modded. Some other stuff.


Inside Majesty folder there is SDK folder that contains guide and examples about modding. There is guide in the "guides" section about modding.

SDK folder contains documentation, examples and original quests to look info from. Main thing is to understand the relationship between mod/quest files.

- .mmxml file contains quest info and references for new xml data and bytecode file .bcd
- .gplproj file contains references to your gpl code files for majesty compiler (Gplbcc) to compile
- makegpl needs .gplproj to get references from it to turn your gpl to bytecode .bcd
- Basically quest/mod needs only mmxml and bcd to function. Also .xml if you add new content. All other files are optional.

some tips:
- don't create *.txt file and rename it to *.gpl. Instead copy existing .gpl and replace its insides
- avoid modifying original game functions. If possible use custom functions for compatibility with other people's mods
- don't multiply integers by decimals.
- run MakeGPL in your system's CLI to check for errors

If you just change values in .xml files make sure to include that .xml file into .mmxml. You can see examples of that in documentation or download some recent workshop quests/modes

This is common way/scheme about what to do to create mod https://imgur.com/a/2Lo4cla

Modding majesty is about scripting mostly. Good examples are Vikesrule's workshop quests/mods like this. Adds new buildings and heroes by repurposing existing things. All quests/mods have the same rules so you can download any to see how the files are arranged.
