Hello everyone!

I am new to Forge, up to now, I used MCreator to write small mods for myself, but now, I wanted to try it with Forge.

So, I have downloaded Xray mod, and saw, that it supports several versions.

So, I wanted to know, how can I make a mod supporting several versions?

I read the tutorial for updating from 1.7.10 to 1.8 (currently on 1.8, but updating as soon as possible).

I thought that a mod can only support a single version? Because, after compiling, the mod gets compiled for version X.X.X, and can only support it.

 

Best regards,

It's only possible to make a mod that supports several Minecraft versions at once if you don't interact with any part of the Minecraft/Forge code that's changed between versions. In practice, any mod that does something substantial is unlikely to work in multiple versions.

 

The only practical way to support multiple versions is to maintain a separate copy of the code for each one. Git branches are a good way to do this.

 

The exception to this rule is 1.10.2, which is 99% backwards compatible with 1.9.4. This means that most mods built for 1.9.4 will work in 1.10.2.

 

Forge no longer supports 1.7.10 at all (threads about it are locked) and I believe support for 1.8.9 is dwindling. I would recommend updating directly to 1.10.2, the only version that's currently receiving bug fixes and enhancements.
