ZZT and Super ZZT world editor
This is a Weave 3 hack of the MIT-licensed release of zedit2 - past versions can be obtained from https://zedit2.skyend.net/ - hacked versions for Weave 3 can be found at https://meangirls.itch.io/weave-3

This is an IntelliJ IDEA project and requires a JDK version of at least 11 (the project is configured to use Amazon Corretto 11 but any JDK 11 should do.)
The code quality is not great - it was originally designed as a fairly simple editor, but then the complexity grew as I added more features and I never got around to giving it a good refactoring. The worst offender is probably the handling of keybinds, where new keyboard shortcuts need to be added in 3 places (to the keymappings array in Settings.java:keystrokeConfig(), to GlobalEditor.java:initProperties() and to WorldEditor.java:addKeybinds()).
Unfortunately I do not have time to maintain this software any more.
