Before posting, make sure you look if your issue isn't already on the forum.
If you have a question about the book itself, be sure to write down the chapter and page.
If you want support related to the code you have, you are suggested to follow this outline:
I have got a problem with my mod.
This is the log from Eclipse or the Minecraft Launcher:
What is happening right now: Detailed description of what is happening.
What is supposed to happen: Detailed description of what you want it to do.
When posting the code make sure you add all relevant pieces of code. However, you shouldn't add every single class in your entire mod. For example for a broken item, the entire mod file and Item class would be useful, but a Block class wouldn't help.
Code can be added and properly color coded and formatted using the { } on the top right of the editor.
