How do I reference a subtype of an item (I think that's what it's called)?

When doing crafting recipes I do this:

new ItemStack(ModItems.fertilizer, 1, 1)

However in this case I want to do

if (tileEntity.getStackInSlot(0).getItem() == subitem)

You would think that you could do 

if (tileEntity.getStackInSlot(0).getItem() == new ItemStack(ModItems.fertilizer, 1, 1).getItem())

but instead it just gets you the default item (fertilizer with a meta of 0). how would i reference a subtype of an item that I could compare that specific type in an if statement?

If your game has references to metadata you're using an unsupported version and you should update.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/: 100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]

What DemonUmbra said, but thought I'd point out this:

"Yes, create a stack that knows about metadata, then discard the metadata, I'm sure it'll be fine!"

ItemStack#areStacksEqual

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I'm super super sorry for posting a non-supported version of forge on here but I've been researching this for 5 days to no avail! I'm really really desperate and any help is needed. It also took my 7 hours to set up this Forge thing on my computer, and I really don't want to deal with another 7 hours of errors which is why I I'm trying to avoid updating. When I finally got it to work with 1.8.9 I was really happy but I don't want to repeat that hell again. Thanks for the help! ALSO! IT WORKED!!! THANK YOU SO MUCH!!!!! I'VE BEEN TRYING TO DO THIS FOR DAYS NOW. And if you think I'm exaggerating about the 7 hours, I'm not lol... my parents came into my room and said "are you alive"? I was up until 1 AM... I was getting gradle errors, java errors, java vm errors, -Xmx256 errors, environment errors, eclipse errors, and I hadn't even started making the mod yet! It just wasn't setting up correctly.... things just kept going wrong. Anyways, it worked!!! thank you so much for helping me! Also acknowledging your description to your forge profile (I think that's a description or a bio? something like that), the fact that you helped me proves that you aren't a jerk. And people who do call you a jerk are just being ungrateful. Trust me, I know. I am an official "Helper" and an "Expert" on the Java discord server, and some people are just complete asses. I will try to walk them through a problem and then they yell at me and say I'm treating them as morons. and I ESPECIALLY agree with you on the statement "If you do not understand Java, I WILL NOT HELP YOU". There are lots of people who just ping me and ask me to do their assignment for them.
