This is a guide to help people get help with their Minecraft errors. A lot of users get errors from minecraft and need help finding a fix, but there are a few steps you should take to ensure that your using the proper etiquette when posting a "Help minecraft crashes because..." post.
Step 1: Post you error log or the crash never happened. Also Please post the entire error log as sometimes what may seem as unimportant to you might be exactly what the person helping you needs to help you. (If your error log closes before you can copy it please skip down to were i explain how to get your error report)
Step 2: USE SPOILERS. this is one of the most important things you can do to help you on your problem solving journey. It is very important to post your entire crash report inside of a spoiler.(example shown below) If you don't use spoilers people may get irritated with you and then less likely to help you with your problem.
This is were your crash report goes
If you do not know how to use spoiler tags here's how:
[spoiler] CRASH REPORT HERE[/spoiler]
Yep not to difficult and it helps out with keeping the forums neat and clean.
Step 3: Be polite. People are much more apt to help if you use words like please and thank you. People are less apt to help if you use things like FIX IT!! or HELP ME!! or things like This mod is stupid it doesn't work for shiz, FIX IT!! Note that the people making these mods are making them because they want to not because they have to. Also the person helping you is helping you because they want to not because they have to.
Step 4: Try to use the best spelling and grammar you can. If you write something out like so:
"plz halp me minecraft crashes and help i need cauz i dont no what wrong." This kind of post wont get much help for a few reasons: 1 you look like a 3yr old so its more trouble then its worth to help you. 2 If you can't even take the time to use spell check then how will we know if you will take the time to try our suggested fixes?
But on the other hand if you use good grammar, good spelling and sound like you are an intelligent person you will probably get help. Now i do understand that for some english isn't there native language and it is difficult please just try your best .
Step 5: Give a good detailed description of what happened before the crash. Note: you do not have to write a wall of text, just give a short and concise answer that is easy to understand.
Now if you get a crash and no error log appears, or it goes away before you can copy it I'll post a link to wiki that explains how to get the error report to come up. Here's the link: http://www.minecraft..._a_Crash_Report
Now if your really to lazy to go look at that i'll post a short overview of what the article says*
Browse to the location of your minecraft.exe launcher.
Shift+Right Click anywhere in the window and choose "Open command window here".
Copy the following code: java -Xincgc -Xmx2048M -cp Minecraft.exe net.minecraft.LauncherFrame
Right click in the command window, select Paste and then press enter.
Login, start Single or Multiplayer and reproduce the crash.
Right click the command windows, choose Select All and Copy
Paste the output to proper mod thread.
*please note: More information will be available on the page linked then i will post here, including instructions for other operating systems then just Windows.
Common errors and how to fix them.
the First and most common error would be this one: java.lang.IllegalArgumentException: Slot 249 is already occupied by
If your error says anything about slot XXX is already occupied by
Then you have a simple ID conflict error and if you don't know how to spot this or how to fix it chances are that you shouldn't be using any mods in the first place. But just to explain, this error is saying that a block ID from your mod is conflicting with a "vanilla" block ID of minecraft yourself. To fix this the mod you are installing should have a config file some were inside your .minecraft folder. Go find that and change whatever block ID is in conflict to one that isn't.
Now some people just have questions that don't always have to do with crash's. So what i suggest you do with that type of question is:
1. Post clearly what your problem is.
2.Post any relevant details.
3.Try and narrow down were the problem is coming from. One thing that could help you narrow things down is have a "control" such as vanilla minecraft itself. Then slowly add mods 1 by 1 until you run into that problem again. This way you can then say something on the forums such as " I get crash "X" when adding mod "Z" to my list of mods "ABCD" The crash happens when I do "verb"
This type of post will be much more helpful and will help you get an answer to your question much faster.
Personally when I have a problem that I need to fix I do a few things.
First off I try to be scientific about it, I try to come up with a theory of what's causing the problem and why its happening then I try to test my hypothesis.Then I move on testing until I have narrowed down the problem. I find that this helps a lot when dealing with multiple mods that could be causing dozens of problems.
Well that's about all I could think of right now. This is just supposed to be a quick start guide for people who are very new to posting errors. If anyone has a suggestion of things I should add or parts I should change, please leave a comment. If not I hope this was of some help and happy mining!
