Frequently Asked Questions

Major Questions

Q: Why is the pack is not appearing on my Modrinth installation? A: Modrinth does not properly install datapacks into worlds directly. You will need to manually insert the datapack and resourcepack into your world's datapack folder and your resourcepack folder respectively.

Q: Why is this visual thing not looking right? A: Install the resourcepack. If you are having trouble finding the resourcepack on Modrinth, click the version you are downloading, not the download button. Scroll down and download the resourcepack.

Q: Is Fathoms compatible with <x>? A: Fathoms is not designed to be compatible with any fishing mods or datapacks. It may be compatible with some datapacks that make minor changes to fishing loot tables (like Myriad), which can be done by Welding packs.

Content Questions

Q: Is this a datapack? A: Yes. We all make datapacks exclusively, not mods. They all use modern technology (and Smithed conventions!) to ensure the experience is integrated just as a mod.

Q: When are you updating this pack to this Minecraft version? A: We don't know, don't bother us about it.

Q: Will there be a Bedrock port for Fathoms? A: We do not make content for Bedrock.

Q: Can you/I port to this Minecraft version/can you/I port to Bedrock? A: No.

Ingame questions

Q: How do I spawn in items/mobs? A: For items, run /loot give @s loot <datapack>:item/<item>. For mobs, run /function <datapack>:commands/summon/<mob>.

Q: I am having an issue that has not been fixed by installing the resourcepack! A: Datapacks are not compatible with lots of server software such as PaperMC made by lazy devs who do not take them into account. If you are running a non-vanilla server software, this may be the reason. Fabric, Quilt, Forge, and Neoforge are probably compatible.

Q: Why am I not catching any of the custom fish? A: Fathoms is not compatible with other mods and datapacks that modify fishing loot tables. We can not fix this.
