Minecraft | Source for programming Minecraft Pi Edition

The problem is that the shadersmod.client.Shaders class was compiled with Java 9 or newer but you're trying to run it under Java 8. Minecraft 1.12 doesn't support running under Java 9 or newer, so your only solution is to recompile it with Java 8.

You're pushing the same list to both current and queued. Java has reference semantics meaning that if you push arrayList to current, current holds a reference to arrayList so if you alter it, current will point to the altered list.

Since you push the very same list to queued, YAML will add an anchor &id001 when the list first occurs, and an alias *id001 to refer to the same list afterwards.

Since you don't want a list in current at all, it seems you want to do

One option is to consolidate your tests in an object, using a shorthand identifier

Never directly compare float values using ==. Due to floating point precision something like 5 * 0.2f / 10f might be 0.99999999 or 1.0000000001 so a check for == 1f would fail!

Therefore you would always rather check if it lies within a certain range like e.g.

The brief answer is: you can't do what you want to do.

Problem is, while I know that the "put" method will never be called at runtime, I don't know if the compiler does.

The put method has to be called at runtime for your mod to be useful. By the time your code is being loaded in a form that it can be executed -- that's runtime. It may be the setup phase for your mod, but it's running in a JVM.

If the source code doesn't contain the registry itself, then the compiler can't translate it to executable code; it can't optimize something it doesn't know exists. You (the developer) can't know what mods will be loading, hence the compiler can't know, hence it can't optimize or pre-calculate it. That's the price you pay for dynamic loading of code.

As for the code you put up: it won't work.

The static block is executed when the class is loaded. Think of it as a constructor for your class instead of the objects. By the time a mod can call any of its methods, the class has to be loaded, and its static blocks will already have been executed. Your map will be set and empty before any method is called from the outside. All tasks added will forever linger in the builder, unused, unseen, unloved.

Keep the builder. Let mods add their entries to it. Then, when all mod-loading is done and the game starts, call build() and use the result as a registry. (Use whichever 'game is starting' hook your modding framework provides.)

The error is due to the scope that you've defined args in. args is defined in your first if statement when it should be defined a line above.

It seems you just placed your embed in your error logger and not in the .then( ... ) statement. But with the minecraft-server-until package, I don't know much about it, so if that wasn't the issue, here is the documentation on the package: https://www.npmjs.com/package/minecraft-server-util

Hope this helps you and have fun developing your Discord API!
