On November 29, 2022 I added in the ability to have stackable items. Any equipment like weapons or armor, which have unique stats, cannot be stacked but most other things can. Stackable items will stack up to a certain limit and can be split or combined. Numbers were added to the bottom left of stackable items to show their count.

Other features added during this time include:

• A trash slot that deletes items when dragged to that slot
• Item catalog that allows you to view all the different types of items, and add them to the inventory
• Scene control window for manipulating lights and fog for debugging

This is also when I solved the issues with the terrain vanishing. It turns out the vertices were the wrong way round, but that wasn’t an issue until the rendering stage for the UI turned on the flag for back-face culling. I set it up properly so we always leave GL_CULL_FACE enabled except when rendering the GUI, and manually reordered the vertices in the terrain.
