Mapmaker Toolkit

Mapmaker Toolkit is a client-side utility mod for Minecraft mapmakers and command creators. It helps you create, visualize, edit, and manage command-style areas directly in the world without placing blocks or constantly checking coordinates.

Have you ever had problems setting up coordinates for detecting players inside an area? Or lost previously saved areas and had to recreate them again? With Mapmaker Toolkit this workflow becomes fast, visual, and easy to manage.

The mod renders selector-style areas based on the coordinates:

x, y, z, dx, dy, dz

These areas are displayed as 3D preview boxes in the world with outlines, optional fill, origin markers, and floating labels that always face the player.

All visualization is client-side only, meaning your world remains completely vanilla-compatible. Players without the mod will not see any overlays.

Core Features

Area Preview

Live 3D preview of areas directly in the world
Optional fill rendering
Corner markers and origin marker
Border color blinks when an entity enters the area
Floating name label for each area

Area Library

Save multiple areas locally
Stored per player in a config file
Rename, copy, delete, and teleport to areas
Easily manage large collections of detection zones

Wand Selection

The mod includes a special wand for selecting areas.

Left click a block → sets the first corner Right click a block → sets the second corner

Once two points are selected, the mod automatically generates a preview area box.

You can then save it directly into the library.

Fast Editing

Look at an area and press K to instantly open the editor.

From there you can:

rename the area
change origin and offsets
toggle outline or fill
teleport to the area
copy the selector format

HUD Toggle

Press J to toggle area previews on or off.

A small HUD indicator shows the current preview state.

Commands

/tk wand

Gives you the Toolkit Area Select wand.

Use it to select two corners in the world to generate a preview area.

/tk wsave

Saves the current wand preview directly into the area library.

This is useful for quickly capturing areas without opening the UI.

Quick Save Shortcut:

If you are holding the wand you can also hold Shift and Right Click on the preview area to instantly:

save the current preview area
automatically start creating a new area

This allows very fast area creation when defining multiple zones.

/tk import

Imports an area from text.

Supported formats:

x y z
x y z dx dy dz
[x=...,y=...,z=...,dx=...,dy=...,dz=...]

This makes it very easy to import existing command areas from datapacks or command blocks.

/tk export

Copies the currently selected area to your clipboard in selector format.

Example output:

[x=100,y=64,z=-30,dx=10,dy=5,dz=10]

You can paste this directly into commands such as:

execute as @a[x=100,y=64,z=-30,dx=10,dy=5,dz=10] run say Player detected

/tk tp

Teleports you to the center of a saved area.

Helpful when debugging datapacks or testing detection zones.

/tk list

Shows the number of saved areas and the first entries from your library.

Quick Tutorial

1. Create Area

Run /tk wand
Left click a block (first corner)
Right click another block (second corner)
Preview box appears

You now have two ways to save it:

Option A (command):

Run /tk wsave

Option B (fast method):

Hold Shift + Right Click on the preview area with the wand

This instantly saves the area and automatically lets you start creating a new one.

The area is now stored in your library.

2. Use the area in commands

Open the editor or use /tk export to copy the selector.

Example command:

execute as @a[x=100,y=64,z=-30,dx=10,dy=5,dz=10] run say Player inside area

3. Import an existing command area

If you already have an area used in commands, you can import it.

Example selector:

[x=200,y=70,z=-40,dx=20,dy=6,dz=15]

Open the mod UI → Add new area to library → paste the selector.

The mod will automatically create a visual preview box for that area.

This means you can easily integrate Mapmaker Toolkit into existing datapacks or maps without rebuilding your areas.

Performance

The mod is designed to remain lightweight even with many saved areas.

Only the nearest 100 areas are rendered
Distance culling is applied
Maximum render range is limited

This keeps performance stable even in large maps.

Compatibility

Client-side mod
Does not modify world data
Does not require server installation for visualization
Areas are stored locally in the mod configuration

Mapmaker Toolkit focuses on making area creation, debugging, and command-based detection zones significantly easier for mapmakers and datapack developers.
