Carpet Mod with HopperOptimizations

Forked from Carpet Mod for 1.12.2

Features

Use /carpet to enable:

optimizedInventories

Optimized Inventory accesses - bloomfilters, cached BlockEntities and improved item transfers. All mechanics should work the same as in vanilla, just with less lag.

optimizedItemStackEmptyCheck

Speeds up checking whether an itemStack is empty by using cached information from vanilla. Mechanics like vanilla.

optimizedEntityHopperInteraction

Reworked interaction between hoppers and entities. Entities look for hoppers instead of hoppers searching for entities. This change should be barely detectable - the order in which items are picked up might be slightly different from vanilla. (For stationary items the order is mostly "oldest first", which is very similar to vanilla)

failedTransferNoComparatorUpdates

Removes comparator updates when item transfers fail. This change is detectable with redstone and therefore clearly non-vanilla behavior.

debugOptimizedInventories

Checks the consistency of internal datastructures used in optimizedInventories on every access. Lots of computational overhead. Will spam console with debug outputs when a bug is detected.

Install

git clone https://github.com/2No2Name/carpetmod112.git cd carpetmod112 ./gradlew setupCarpetmod ./gradlew genPatches ./gradlew createRelease Drop all files from build/distributions/Carpetmod_dev.zip into the 1.12.2 server jar to install carpet. Do not unpack the jar archive to do that. Use that jar as your server jar.

Getting Started

Setting up your sources

Clone this repository.
Run gradlew setupCarpetmod in the root project directory.

Using an IDE

To use Eclipse, run gradlew eclipse, then import the project in Eclipse.
To use Intellij, run gradlew idea, then import the project in Intellij.

Using the build system

Edit the files in the src folder, like you would for a normal project. The only special things you have to do are as follows:

To generate patch files so they show up in version control

Use gradlew genPatches

To apply patches after pulling

Use gradlew setupCarpetmod. It WILL overwrite your local changes to src, so be careful.

To create a release / patch files

In case you made changes to the local copy of the code in src, run genPatches to update the project according to your src. Use gradlew createRelease. The release will be a ZIP file containing all modified classes, obfuscated, in the build/distributions folder.

To run the server locally (Windows)

Use mktest.cmd to run the modified server with generated patches as a localhost server. It requires gradlew createRelease to finish successfully as well as using default paths for your minecraft installation folder.

In case you use different paths, you might need to modify the build script. This will leave a ready server jar file in your saves folder.

It requires to have 7za installed in your paths
