🔥 下界传送门坐标计算器（Minecraft）Nether Portal Calculator (Minecraft)

使用说明与常见问题How-to & FAQ

「下界传送门坐标计算器（Minecraft）」是什么？What is the Nether Portal Calculator (Minecraft) tool?

把 Minecraft 主世界坐标换成下界坐标（X、Z 除以 8），或反过来乘以 8；给出游戏实际使用的方块坐标（向下取整），Y 保持不变并提示下界高度范围，帮助两边的传送门正确连接。本地处理。Convert Minecraft Overworld coordinates to the Nether (X and Z divided by 8) or back (multiplied by 8), with the block coordinates the game actually uses (rounded down). Y stays the same, with a reminder of the Nether height range, so your portals link up. Processed locally.

如何使用「下界传送门坐标计算器（Minecraft）」？How do I use the Nether Portal Calculator (Minecraft) tool?

在「下界传送门坐标计算器（Minecraft）」中，填写「方向」、「X」、「Y（可选）」、「Z」等参数，结果会随输入实时计算并显示在下方。In the Nether Portal Calculator (Minecraft): Fill in "Direction", "X", "Y (optional)", "Z"; results are recalculated instantly as you type.

为什么要除以 8？Why divide by 8?

在 Minecraft 里，下界每走 1 格相当于主世界的 8 格（只算 X 和 Z），所以主世界坐标 ÷ 8 就是下界里对应的位置，下界坐标 × 8 回到主世界。In Minecraft one block in the Nether equals eight in the Overworld (in X and Z only), so Overworld coordinates ÷ 8 give the matching Nether spot, and Nether coordinates × 8 take you back.

Y 坐标要换算吗？Do I convert Y as well?

不用，Y 不按比例换算。但下界顶部是基岩（Y 128），传送门要放在下面，游戏会在附近找合适的高度。No, Y is not scaled. The Nether has a bedrock roof at Y 128, so the portal has to sit below it and the game picks a suitable height nearby.

传送门连错了怎么办？What if my portal links to the wrong one?

进入传送门时，游戏会在对应坐标附近找已有的传送门（Java 版主世界约 128 格、下界约 16 格内），找到最近的就连过去。把下界那一侧的传送门建在换算出的方块坐标上，就能连到正确的一个。When you enter a portal, the game looks for an existing one near the matching coordinates (about 128 blocks in the Overworld and 16 in the Nether in Java Edition) and links to the closest. Building the Nether-side portal at the converted block coordinates links it to the right one.

能举个计算实例吗？Can you show a worked example?

例如在「下界传送门坐标计算器（Minecraft）」中填 方向 = 主世界 → 下界，X = 800，Y（可选） = 64，Z = -1600，结果区显示：下界坐标 X, Z：100, -200；方块坐标（向下取整）：100, -200；Y：64（不按比例换算）；ℹ 下界 1 格 = 主世界 8 格（X、Z）。Java 版找已有传送门的范围：主世界约 128 格，下界约 16 格，所以两边坐标要尽量对准For example, entering Direction = Overworld → Nether, X = 800, Y (optional) = 64, Z = -1600 in the Nether Portal Calculator (Minecraft) gives: Nether X, Z: 100, -200; Block coordinates (rounded down): 100, -200; Y: 64 (not scaled); ℹ 1 Nether block = 8 Overworld blocks in X and Z. In Java Edition the game looks for an existing portal within about 128 blocks in the Overworld and 16 in the Nether, so…

哪些输入会被检查？Which inputs are validated?

「下界传送门坐标计算器（Minecraft）」会检查这些输入——「X」：所选方式用到时必须填写；「Y（可选）」、「Z」：可留空；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Nether Portal Calculator (Minecraft) checks its inputs — "X": required when the chosen option uses it; "Y (optional)", "Z": optional; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

The result always uses the current settings.
