BlockZ
by yitian77
BlockZ is a Forge survival mod for 1.20.1 that reworks the player inventory into a grid where items are placed and rotated like Tetris pieces.
What it does
BlockZ pays homage to the DayZ survival games, bringing a hardcore survival experience to Minecraft with DayM-style gameplay. Players begin with very little pocket space and must scavenge for backpacks, vests and clothing with pockets to carry more. Backpack management becomes part of the survival challenge, since the inventory logic is rebuilt around a realistic Tetris-style grid.
Injuries are handled by an optional nursing system covering bleeding, fractures and analgesics, shown with HUD status icons, progress bars and actionbar feedback. Each part of the mod can be switched off in the configuration file, including the DayZ HUD overlay, the hints and the nursing system, and the UI can be returned to the original style by a button or command while the capacity limit still applies. Geckolib is required. Curios API and Thirst Was Taken are optional.
BlockZ is open source under the GNU General Public License v3.0 only and runs on client and server, so both the server and every player need it. Files target 1.20.1 alone, with the 1.1.6-Beta-fix file on the beta channel as the latest release.
Key features
Grid item rotation
Pressing Space rotates an item while it is dragged, so items fit into the gaps of a backpack.
Dynamic pocket expansion
Storage grows as players equip backpacks, vests and clothing with pockets found in the world.
3D item preview
Dragging an item through the inventory shows a model preview of how it will look on the grid.
Equipment variety
Lightweight patrol bags and large-capacity Coyote Backpacks offer different slot layouts.
Custom grid colors
Each item's grid color can be set in the items.json file to customize the background panel.
Curios slot support
With Curios API installed, backpacks, vests and masks equip and sync through the back, body and head slots.
Injury status icons
Bleeding, fracture and analgesic states appear on the HUD with progress bars while they last.
