    What I can show is a block or item or armor etc. but That's far from a rail.

    A rail is a block, so it's not far at all. Make a custom block that extends the rail class (or its base class).


    What's far away is the minecart entity, which I told you to study. What did you learn?

    Sorry but are you read what I write? I completed thew simple tutorials, AND looked into the source code.

    Yes, and I just read it again to be sure. You found a tutorial but gave no indication that you had completed a simple mod. Perhaps your writing is not as clear as you imagine.


    Others have played with rail mods. Try to find an example at github.

    useful resources for learning

    Many mods have been put up at github. If you Google this forum for github references, you can follow the links to see examples of what other modders have done (some are better to emulate than others).

    The problem is that every single step in world generation takes too long

    If one of those long steps includes a call to another method, then step INTO it instead of over. Drill down until you find yourself somewhere you shouldn't have gone (like loading and unloading huge piles of the same data again and again).


    Do whatever it takes to get over your debugger-phobia. Stop making excuses; just get inside the bloody program to see what it's doing while it's doing it. Learn the features of the debugger so you can use it effectively instead of giving up with a vague "every step takes too long". What was it doing? Why didn't you step into the call(s) to see why? Get in there again and drill down until you find the problem.

  4. As usual, mysterious runtime behavior demands an investigation in the debugger. Set breakpoints that will stop execution when you reach the problem stage of the game. When you get there, then set more breakpoints in methods that you want to why they're even being called. When they hit, look at the call stack. Home in on your problem from there and do some stepping. If chunk gen is really running away, then the "why" should become obvious after an iteration or three.

    I a beginner modder

    I highly recommend that you complete a simple mod as an exercise before venturing into more creative territory. There are plenty of mistakes you can make in the simplest of mods, so you should make and learn from them so your later work will be less frustrating.


    Then when you investigate rail, look into both rail blocks and minecart entities. You may discover that the behavior you need to modify is programmed into the cart, not the rail.

    jeffryfisher doesn't just mean using the actual debugger.

    Actually I do. I want to see more people post what they see when they STEP line-by-line through their code (and affected vanilla code) surrounding mysterious run-time behavior. It's often quite illuminating. Inexplicable runtime behavior should send you to the debugger before it sends you here.


    And yes, there are other debugging techniques to instrument your mod so you can learn what is happening inside of it.

  7. Some of the vanilla sound methods run on the server and send packets to all listeners (players). Other methods act like renderers, only existing or running on the client, often downstream from the packet handlers. Unfortunately, much of the naming is similar, so Minecraft's sound system is confusing. IIRC, PositionedSound is client-side only.


    You need to analyze these classes and then organize your code so that you make decisions on the server that cause sounds to be rendered on the client. In many cases, you do not need to design your own packets and handlers; vanilla will handle that for you.


    I recommend setting some breakpoints and then stepping through the process for some vanilla sound in debug mode. That'll show you in a hurry what calls what where.


    You should also read about sound in the Forge docs.

    Does anyone have a simple full example of doing something more?

    You can Google for "github" at site:http://www.minecraftforge.net/forum/topic

    You can go to github and then search for Forge projects.


    Stick to mods using the same version of Minecraft (1.12.2). After looking at a few, you'll quickly distinguish between matters of style versus matters of necessity. You'll also quickly get a sense for who knows what he's doing (and who knows even less than you do).


    Once you've settled on one or two worthy examples, emulate them (don't cut and paste). You learn by assimilating and doing.


    Finally, when you are getting ready to run something, run it in debug mode (with some break points set within your own code). Step through and into the various methods, examining some of the changing fields as you go. More than any static examination of vanilla code can ever teach you, a ride-through will illuminate how the program functions. Try to scan each operation at least once so you have some idea how it hangs together. No need to sit through 500 cycles of a loop, but try a few at least once.


    And have fun.

  9. IIRC, LWJGL =  LightWeight Java Game Library


    Are you missing LWJGL or a DLL it needs? But it should have emitted an error if that were so...


    Maybe there's a version mismatch. Did you install on top of an earlier (or worse, a later) version of Forge?


    I think you showed us console output. Have you dug up the actual log files? They contain more gruesome detail, so there might be a further clue.

    I can't figure out how to do this.

    Start by learning Java (elsewhere, there are many online tutorials), which you should be able to do in a couple weeks. Then install Forge's development system, described in detail elsewhere on this site.

    please tell me where to put whatever code you might send

    Don't worry, you shouldn't be asking for code to be spoon fed to you, so you won't need to be told where to put any. However, what you can do (after learning Java and installing Forge) is to Google for Forge mods at GitHub. You can see code and how it's organized by successful modders.
