Why?

You're running Minecraft + Forge for 1.11.2 with Optifine for 1.7.10.

It's an issue with AM2, report it to the author. And the next time, please post the complete FML log.

Post the FML log (logs/fml-client-latest.log). Also, check if all the mods are for the right version and the latest version.

Read the EAQ and follow the instructions.

logs/fml-client-latest.log in your profile folder.

Which means it's called on the client-side. On the client-side, you can use the Minecraft class which contains a lot of information about the game, including the player and the world he's in.

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Architects, Builders and Designers Mod (abad) Caused by: java.lang.NullPointerException at com.scorpiocruz.abad.init.ModItems.registerRender(ModItems.java:46) The error is caused by the Architects, Builders and Designers mod. Report it to the author.

After a bit of Googling, I think it means "always run without a prompt asking you if it's safe to run a JAR file", rather than "this program is running 24/7". Assuming you downloaded Forge from the official file server, it should be safe.

You're using 1.7.10. 1.7.10 is no longer supported on this forum. Update if you want support.

You'll have to wait until the site's back up.

If you're just reading books and not writing any code, you're not learning. You are remembering. Have you written anything in Java besides Minecraft? You really should.

If you look at the class, you can see all the methods you can call on it, including ways to get an instance of ServerData (ServerList#getServerData(index)).

Don't post in threads that have been inactive for a long time (like October 2015....). Make your own topic.

ServerData contains the name, IP and other information about a server.

Please don't post in topics that are a year old. Make your own.

Yes, the constructor of ServerList takes an instance of the Minecraft class, which you can get using Minecraft.getMinecraft().

new ServerList?

Pam's HarvestCraft seems to override the BlockCrops#updateTick method and don't call the super method. You should contact the author or make a pull request to either call the super method or call the event itself.

You can make a new instance of ServerList using the Minecraft class (AKA client-side-only), and call the ServerData#loadServerList method, which will read the servers into a List<ServerData>. ServerData has multiple methods to get/remove/modify the List<ServerData>. This might not be the best way to do it, I couldn't find a better way in the little time I spend researching.

1.7.10 is no longer supported on this forum. Update for further support.

Override Item#shouldCauseReequipAnimation to return false when you don't want the animation.

What file did you run and how did you run it?

1.7.10 is no longer supported on this forum. Update to a newer version (1.10.2 or 1.11.2).
