Map Editor for Lines Of Battle!

Quick video showcase https://youtu.be/Fo3VIW98ktY

How to install

1. Head towards releases section here.
2. Find your installer depending on your operating system(.exe and .msi for windows, dmg for macos, etc). Or use .jar(you need java 21 in order to run) file of the editor.
3. Install and enjoy the application.

Features

It has almost all features from the original map editor. Also we added a lot of new ones.

Better editing experience

Create your high-quality maps in no time.

Better perfomance

The application uses OpenGL and a lot of heavy tile blending calculations are shifted to GPU. You can even create the biggest available map(200x152 tiles) and it will only have a slight perfomance drop at the beginning.

Almost identical render

The editor was created with this idea in mind, so what you see in the editor will be the same in the game.

Improved grid visibility

In the map editor the grid(even thin one) will render correctly whereas official map editor has some grid glitches.

Open-source

Make your forks or contribute to the project directly heling the community and the project.

Keybindings

• Ctrl + g - toggle grid
• Ctrl + r - toggle show reference
• Ctrl + q - terrain pick
• Ctrl + z and ctrl + shift + z - undo/redo.
• Delete - delets selected units or objective.
• Ctrl + d - duplicates selected units or objective.
• Shift + LMB on a unit - add the clicked unit to selected ones.
• Ctrl + LMB on a selected unit - exclude the clicked unit from the selection.
• LMB drag - selects units within the selection box.
• LMB drag on selected units or objective - Moves selected objects.
• LMB drag on blue arrow - changes the selected units rotation.
• MMB drag - move camera.
• RMB - use current tool.

A lot of tools

There are 8 tools, in order to use one of them - just click on it.

Export/Import

Import your map from json. Or export the game compatible json type.

Techstack

• OpenGL - API for low-level rendering, gives insane boost in perfomance.
• JOGL - binding for OpenGL for java.
• JOML - Linear algebra library designed for OpenGL.
• Kotlin compose - Modern UI framework for android and desktop applications.
• Jewel UI toolkit - jetbrain-like UI toolkit.
• Kodein - DI library that allow us to wire everything easily.

Contribution/Building from the source

In order to initialize the project run:

./gradlew :composeApp:generateResourceAccessorsForCommonMain

./gradlew :composeApp:generateResourceAccessorsForJvmMain

Also, you might want to run some init tasks like ./gradlew init.

In order to run execute:

./gradlew run

P.s. If you are using windows then you should use gradlew.bat instead of gradlew
