Another sneak preview of GB Studio 4 now with more bug fixes! Everything still subject to change, so make sure you keep plenty of backups of your projects.

If you have any issues with your music not sounding the same, there is a migrator tool available at https://chrismaltby.github.io/gbs-uge-migrator/ (backup before using this too!)

[4.0.0-beta1]

Added

• Add support for << and >> operators in math expressions @pau-tomas
• Add script debugger pane to World view, when game is run while this is open allows inspecting currently running scripts, setting breakpoints and updating live variable values
• Add 'Color Only' mode. Roughly doubles the amount of tiles available for backgrounds and sprites though game will no longer run on original GB (DMG) hardware
• Add event "Replace Tile At Position" and "Replace Tile From Sequence" to update background tiles, calling "Replace Tile From Sequence" repeatedly will cycle through animation frames
• Add new asset folder "Tilesets" for use in "Replace Tile" events
• Add ability for plugins to define additional scene types by including defined types (e.g. "sceneTypes": [{"key": "RACING", "label": "Racing 2D"}]) in engine.json @pau-tomas
• Add ability for Actor Move Relative, Actor Set Position Relative and If Actor At Position to use variables as coordinate inputs
• Add ability for almost every script event input that supports variables to use advanced values, click the button to the left of the value input to select value types, and combine them with math operators

• Add stack preview mode to debugger
• Add ability to set common tilesets between scenes, the common tiles will always be loaded in a consistent order between scenes sharing the same common tileset

• Add ability to override tile data for auto colored backgrounds by providing a matching *.mono.png in your assets/backgrounds folder containing a monochrome version of the background. When provided this file will be used for tiles data and the regular image will be used to extract the color palettes (useful for mixed color mode games when auto palettes isn't creating tile data as you'd like automatically)
