Mod i remade from yyzsbackpack by yyz729.
Functionality:
Adds 54 locked slots for each player, and each slot is unlocking by completing 5 (default) achivements (if you play vanilla mc with no mods that adding achievements, you can change this value to 2, for example [you can calculate needed value by yourself - divide total number of achievements (vanilla java 1.21.1 has 126) by 54 and floor that value to integer]).
Configuration (config/progressive-inventory.toml):
#What happens to your items in progressive inventory after death. Default means using keepInventory gamerule behaviour.
#Allowed Values: DEFAULT, DROP, SAVE
keepItemsAfterDeath = "DEFAULT"
#How many advancements player should complete to unlock 1 slot (out of 54 total slots)
\# Default: 5
\# Range: 1 ~ 100
advancementsPerSlot = 5
If you set keepItemsAfterDeath to SAVE, items will not drop from player after death, even if keepInventory gamerule is disabled.
You can press TAB (default) key to sort slots. To prevent certain slots from changing their positions, you can pin them by pressing Alt+LMB.
