Is the Forge API backwards compatible?

Posted July 1, 20241 yr

Hello, I'm new to the forum so please guide me instead of attacking.

I'm a frequent Hypixel player, a server exclusively played on 1.8.9 - and I want to create a mod for it.

Not asking help for that forge version, but I do want to know whether I can just develop my mod against the latest 1.21 API and it would work on 1.8.9? am I forced to use the 1.8.9 API?

Merged your questions, you didn't really need to make 2 posts, considering they are the exact same question with 2 different subject lines.

You need to use the forge version for the MC version you wish to mod. There are so many differences between versions in the Minecraft codebase, especially at certain points, that Forge had to make compatibility breaking changes to keep up.

For some odd reason it created a second post after I just edited the title...

Anyway, thank you for the info!

(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
