Splash Factorial Math

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Resource pack only.

⬇ Download for 1.20.5–1.21.3 ⬇ Download for 1.20.2–1.20.4 ⬇ Download for 1.20–1.20.1 ⬇ Download for 1.19.4 ⬇ Download for 1.19.3 ⬇ Download for 1.19–1.19.2 ⬇ Download for 1.18–1.18.2

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

16 + 1 + 4 is not 21!

One of the splash texts says "Java 16 + 1 + 4 = 21!" and this is incorrect. Clearly, there is not a single person at Mojang who can understand math, if Mojang thinks that 21 factorial is only 5 more than 16. This resource pack fixes this gamebreaking bug to make Minecraft playable again by changing the splash text to "Java 16 + 51,090,942,171,709,439,980 + 4 = 21!"

16 + 1 is not 17!, either!

From 1.18 to 1.20.4, Minecraft was running on Java 17. As such, the incorrect splash text previously read "Java 16 + 1 = 17!", which is also wrong. Never fear, this resource pack has support for all affected versions, and as such, versions below 1.20.5 change the splash to "Java 16 + 355,687,428,095,984 = 17!"

Why is this fix necessary?

It should be obvious.
