WHAT ARE WE WORKING WITH
--Dimension, DimensionType, ServerWorld
	-- There exists a 1:1:1 relationship between each of these, e.g. there will be one DimensionType instance
		and one Dimension instance for a given ServerWorld, and those DimensionType and Dimension instances will only be
		used on that worldserver
--ServerWorld
	-- The server-specific version of the World, which holds all the block and chunk data, entities, tile entities, etc.\
		for a given dimension. You won't be making these yourself or extending the class, but you'll need to find and use the
		ServerWorld for	your Dimension to teleport the player there.

I'm going to attempt to give a fair comparison of how well CarpetMod would work as a Jar Mod vs a Fabric Mod in the future, then give my opinion at the end.

Jar Mods

Jar Mods are what the 1.12 and 1.13 versions of CarpetMod currently are. They basically work by us directly modifying vanilla classes directly. Quick rundown of the process that isn't too in-depth: in order for us to do this, we must first translate the bytecode which Java executes into readable source code that we can understand and edit. This process is called "decompilation". Then, after we have edited the classes, we translate the code back into back into bytecode which Java can execute ("recompilation"). We then distribute parts of the code we have made changes to. Recompilation is very trivial and is unlikely to contain any errors at all. Although we use the best decompiler that exists (ForgeFlower), decompilation is still not 100% accurate.

Fabric Mods

QuickCarpet for 1.14 is a Fabric Mod. Fabric Mods are loaded by a mod loader cal

If a command breaks, use --no-daemon as the ForgeGradle currently doesn't uses it

Setup MDK (For Modders who want to create a mod)

• Download the MDK from forge (Forge Test Version for 1.13)
• ./gradlew eclipse
• ./gradlew genEclipseRuns to generate the launch configuration
• (./gradlew genIntellijRuns for IntelliJ users)
• run this two times so the libs get properly linked
• Importing into IDE has not changed

Decompiling

1. Clone MCPConfig from the GitHub repository.
2. In the root project directory, run gradlew :1.13:projectClientApplyPatches if you want to make a client side mod, or gradlew :1.13:projectServerApplyPatches if you want to make a server side mod.
3. Naviage into versions/1.13/projects/server (or client). There are a couple of fixes necessary to get the code to compile:
   1. There is a missing class mcp.MethodsReturnNonnullByDefault which you will have to manually add. A copy can be found here.
   2. If you're making a server-only mod, the anonymous classes in net.minecraft.item.ItemClock and net.minecraft.item.ItemCompass need to be modified to override the method in net.minecraft.item.IItemPropertyGetter. This is never actually called on the server so you can make a dummy implementation.
4. Copy versions/1.13/projects/server (or client) into a separate

OpenGL calls, OpenGL state, and state leaks

Making OpenGL calls has a performance cost. It is therefore desirable to reduce the amount of calls.

OpenGL has global state. The state is modified by enabling/disabling blending/culling/alpha testing/etc, specifying the blend function, changing the cull face, etc.

A state leak happens when a method leaves OpenGL in a different state after being called. This is generally undesirable as it often breaks expectations about the OpenGL state in other methods.

Modifying the OpenGL state requires OpenGL calls. Minecraft is not particularly optimized for reducing the amount of OpenGL calls, but makes an attempt using GlStateManager.

BUT do note that this can be updated, so leave a link here so readers can see the updated information themselves.

1.13 and 1.14 are lumped together in this doc, you're on your own if you just want to go to 1.13 and not 1.14, for some reason.

1.15 stuff: https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e

Things in Advance

• ResourceLocation now throw on non-snake-case names instead of silently lowercasing for you, so you probably should go and change all those string constants now. More precisely, domains must only contain alphanumeric lowercase, underscore (_), dash (-), or dot (.). Paths have the same restrictions, but can also contain forward slashes (/).

// This is a janky JSON generator, for porting from below 1.12 to 1.12.
// Simply replace calls to GameRegistry.addShapeless/ShapedRecipe with these methods, which will dump it to a json in RECIPE_DIR
// Also works with OD, replace GameRegistry.addRecipe(new ShapedOreRecipe/ShapelessOreRecipe with the same calls
// After you are done, call generateConstants()
// Note that in many cases, you can combine multiple old recipes into one, since you can now specify multiple possibilities for an ingredient without using the OD. See vanilla for examples.
