Updating Existing Chunks in a Custom World
If you're using a custom world generator or importing a single-player world and need existing chunks to be updated automatically, this scanner is a great solution.
Important: Run Chunky first to pre-generate your world. This greatly reduces lag and ensures the scanner only needs to visit already-generated chunks.
Set the scanner boundaries to match the radius you used in Chunky:
In this example, Chunky was used to generate a world with a 12,000 block radius (24,000 blocks wide).
The scanner will:
Think of it like reading a page of text—left to right, then moving down to the next line.
This method is useful for:
While it is slower than running the scanner directly on a server, it provides a simple way to automate chunk loading and upgrading in a standard Minecraft installation.

Set the scanner boundaries to match the radius you used in Chunky:
In this example, Chunky was used to generate a world with a 12,000 block radius (24,000 blocks wide).
The scanner will:
- Start at X -12000, Z -12000 (top-left corner).
- Move across the map from left to right.
- Once it reaches the end of a row, move down and begin the next row.
- Continue until the entire area has been scanned.
Think of it like reading a page of text—left to right, then moving down to the next line.
This method is useful for:
- Updating chunks after changing world generation settings.
- Converting imported single-player worlds.
- Triggering chunk upgrades after Minecraft version changes.
- Ensuring all chunks are loaded and processed by the server.
Single-Player Worlds
If you're importing a world from single-player Minecraft, I've also included a PowerShell version that works with vanilla Minecraft and requires no mods or plugins.While it is slower than running the scanner directly on a server, it provides a simple way to automate chunk loading and upgrading in a standard Minecraft installation.

# AUTO TELEPORT SCANNER
#
# This script teleports a player in a grid pattern across
# the world. It is commonly used for:
#
# - Chunk generation
# - Map pre-loading
# - Searching large areas
# - World border scans
#
# Commands:
# /tpstart = Start scan from beginning
# /tpstop = Pause scan
# /tpcont = Continue scan from current position
# /tpreset = Reset position back to start
# /tpstatus = Show current coordinates
#
###########################################################

Minecraft TP Paste Grid
- Click into Minecraft chat/window when prompted.
- Script pastes /tp commands using clipboard paste, then presses Enter.
- Starts at X=12000, Z=12000.
- Z decreases by 100 each teleport.
- When Z reaches below -12000, X decreases by 100 and Z resets to 12000.
- Stops if X or Z would go below -12000.
