Free Minecraft Tools

Quick answers

Each tool here comes with the reference material behind it, because a number without an explanation is only useful until the game changes. These are the questions the four tools get asked most.

How do I convert Overworld coordinates to the Nether?

Divide X and Z by eight and round down; leave Y alone. The Nether is compressed horizontally by a factor of eight, and that compression has never applied to the vertical axis. Rounding down rather than truncating matters on the negative side of the world: −100 ÷ 8 is −12.5, and the block containing that position is −13, not −12. Convert coordinates and read the portal linking rules.

Why did my two portals end up linked to the same place?

Portals do not remember each other. Every trip converts your position and searches the destination for a portal nearby — a 16-block radius when arriving in the Nether, 128 blocks when arriving in the Overworld. Two Overworld portals within about 128 blocks of each other convert to Nether coordinates within 16 blocks, so both searches land on the same portal. Build the destination portals yourself if you want them to stay separate.

Should my circle have an odd or even diameter?

Odd if you want a single block at the centre, which is what you need for a tower, a pillar or anything built around an existing block. Even if you are centring on the corner where four blocks meet. Getting this wrong is why a build ends up one block off inside its own footprint, and it cannot be fixed later without rebuilding. Generate a circle and see the block counts by diameter.

Why doesn't my banner /give command work any more?

Java Edition 1.20.5 replaced item NBT with item components, and the old BlockEntityTag banner syntax no longer parses. Commands written before that release fail outright rather than degrading. Bedrock Edition never used that syntax at all — its /give cannot apply banner patterns, only hand you a blank base banner. Design a banner and get the command for your version.

Why does my server MOTD look wrong on Bedrock?

Probably §m or §n. In Java Edition those are strikethrough and underline. In Bedrock Edition they are colours — redstone and copper — and Bedrock has no strikethrough or underline at all. The two editions also disagree about whether a colour code clears formatting: Java clears it, Bedrock does not. See every code and how the editions differ.

Which colour is "green"?

There are two answers, and they are the reason a banner never matches the text above it. The chat colour behind §a is a bright #55FF55. The dye that tints banners, wool and leather is a muted #5E7C16. Two separate sixteen-colour palettes share most of their names, and the dye palette has colours — brown, magenta, cyan — that the chat palette cannot express at all.

Which versions does this cover?

Everything here is checked against the Minecraft Wiki and states which edition and release it applies to whenever the two differ, which is more often than most references admit. Where a mechanic changed — the Nether portal search radius in 1.16.2, the item component rewrite in 1.20.5, the loom pattern items in 1.21.2 — both the old and the current behaviour are described, because plenty of servers are still running the old one.
