I want to modify a class from another mod using my mod.

Is there a way to swap the functionality of an existing item from another mod? How could I do that?

 

 

Thanks.

Short answer is don't do that.

Speak to the original mod author about getting the behaviour you want.

Or if they don't want to do that, create your own item and let end users or modpack developers choose to use your item by modifying the crafting recipes.

My idea in making these modifications is because I want to create a mod for a custom modpack, and some mechanics from certain mods could interfere, since the modpack would modify many things.

Then just create your own item and override the recipes to produce your item as the output.

To make it work properly, you will need to specify "AFTER" as the ordering in the mod dependencies in your mods.toml

Or you can use a mod like Kubejs or crafttweaker to modify the recipes using a script.
