📋 About This Mod
# Stackable shulkers fix A simple addon to the (https://www.curseforge.com/minecraft/mc-mods/carpet) that fixes the 1.20.5+ behaviour of stacked shulker boxes to be the same as in older versions, as well as some optional features. ## Features > **NOTE** Features marked as `intrusive` are modifying the standard behaviour in their default state. This is done to maintain compatibility with older versions of the mod. ### Fixed hopper transfers Prevents hoppers from stacking shulker boxes, even if the max count is >1. *Setting this rule to `false` enables the functionality of this mod by preventing shulkers from being stacked by hoppers.* - Name: `hopperShulkerStacking` - Type: `boolean` - Default: `false` - Categories: `shulkerfix`, `bugfix`, `intrusive` - Since: `1.5` ### Fixed comparator output Changes how stacked shulker boxes affect comparator output: 1. `true`: Shulkers have signal strength of unstackable items, allowing output up to 897 (AKA OSS/HSS); 2. `false`: Shulkers have signal strength of stackable items, reaching 15 when all slots are full (hoppers won't be able to fill over SS1); 3. `capped`: Shulkers have signal strength of unstackable items, but the resulting output is capped at 15. This implementation preserves overstacked item filters. 4. `normalized`: Any amount of shulkers in a slot is counted as a single unstackable item. This limits the output to signal strength 15 and patches overstacked item filters. - Name: `overstackedShulkerSignalStrength` - Type: `string` - Default: `true` - Options: `true`, `false`, `capped`, `normalized` - Categories: `shulkerfix`, `bugfix`, `intrusive` - Since: `1.7.1` ### Legacy shulker item merging Reintroduces the logic for merging shulker box items before 1.20.5. The implementation allows partial item merging *(normally the game doesn't merge item stacks if the total amount is more than the max size)* and resets the entity age, allowing faster merging. *(Both were bugs in Carpet, but no one complained, so now we're reintroducing the bugs huh)* - Name: `legacyShulkerItemMerging` - Type: `boolean` - Default: `false` - Categories: `shulkerfix`, `experimental` - Since: `1.6` ### Hopper collection Makes hoppers pick up one shulker at a time from an entity stack. Note that this has a risk of breaking contraptions. - Name: `hopperCollectSingleShulkers` - Type: `boolean` - Default: `false` - Categories: `shulkerfix`, `feature`, `experimental` - Since: `1.5` ### Hopper minecart collection Makes minecarts pick up one shulker at a time from an entity stack. Note that this has a risk of breaking contraptions. - Name: `minecartCollectSingleShulkers` - Type: `boolean` - Default: `false` - Categories: `shulkerfix`, `feature`, `experimental` - Since: `1.5` ### Minecart slowdown Disables the additional slowdown caused by overstacked minecarts. The implementation makes shulker boxes count as 64-stackable when calculating the minecart slowdown. However if `overstackedShulkerSignalStrength` is enabled, reading the fill level will still output the overstacked value. *Setting this rule to `false` enables the functionality of this mod by removing the additional slowdown.* - Name: `overstackedMinecartSlowdown` - Type: `boolean` - Default: `true` - Categories: `shulkerfix`, `feature`, `experimental` - Since: `1.5` ### Client count fix Fixes (https://github.com/gnembon/fabric-carpet/issues/1899), where vanilla clients see stacked shulker boxes as single items inside containers. - Name: `clientShulkerSync` - Type: `boolean` - Default: `false` - Categories: `shulkerfix`, `bugfix`, `experimental` - Since: `1.4`
