This is the new 2 version of my flexible inventory system for Game Maker. You can create many inventories with simple functions! Drag and drop windows and items. You can change inventory colors or set backgrounds and slot sprites. Unlike version 1, this one has simplified functions and works on structs rather than regular objects, the exception being the controller object. It also has more flexible customization, works faster, has the ability to save and load items, and easy sorting of items!
You can check out the 1st version for free! In my account here or on itch.io First version
