First be sure you doc the way you anticipate individuals to mod your sport and the related file codecs. And in your group hub (you will want one) have a mods part for individuals to debate that sort of factor.
The best method is to arrange your sport to permit it to load information and asset recordsdata from the a folder within the regular save listing you may name “mods”. That alone can allow easy issues like texture swaps and customized maps and fashions.
A way more concerned method is to make scripting entry so modders can have their very own code run in response to sure occasions within the sport. It is a endeavor to say the least, and it runs the chance {that a} sure function that modders may wish to change wasn’t made out there to vary, limiting the sort of mods that may be made.
A deeper mod entry might be had by dynamically loading mod libraries and giving them direct entry to the related engine internals based mostly on the headers/api you publish as if that library was one you wrote and compiled individually. Loads of unity video games are modded this manner as a result of C# binaries are simply inspected and reflection permits a “mod loader” to hook into the related issues to inject code as wanted. And it is how java minecraft is modded.
If you need a sport to be unmoddable then compile completely to native code, run it via an obfuscator and do issues like checksum completely different elements of the code and the stack return addresses at runtime to make sure no one modified issues behind your again. That does not make it completely unmoddable but it surely does ship a message.
