Ablaze

Hey! I'm trying to generate my custom tree. But I keep getting an error. Here are my files:- Main Class - Tutorial.java BlockArkmanditeLog.java BlockArkmanditeLeaf.java BlockArkmanditeSapling.java ColorizeLeaves.java EventManager.java ArkmanditeWorldGenTrees.java Stack Trace (there was more above this, but my console didn't hold all of it..) Please help me if you can. Regards, Ablaze.

Hello there! My name is Ablaze. I started modding a week ago and I'm loving it. But I'm having too many, lets say, "doubts", or "how-to-do-this" things. So I would like a live tutor(am I going to receive great criticism about this? Hope not.) who is mostly free and has a Skype so he can teach me about new things. I like to learn. Anyways hopefully you will consider this, and help me out. Please don't shout - "GO FREAKING WATCH SOME TUTORIALS!" or "NO ONE HAS TIME TO TEACH YOU PERSONALLY!!!!" . If you can't, just move on. If you can, please do. Regards, Ablaze.

Hello everyone! My name is Ablaze. I was impressed by the forum with my last topic. I had 4 replies by the next day of the OP. Anyways, here is my newest problem. I got into modding 3-4 days back. I don't mind if I have a coding error; in the sense a problem in the code. I will Google as much as possible, and rack my brains to figure it out. But this one is a real bad one. It isn't an error. When I run Minecraft through eclipse, this is the log i get:- Aug 28, 2013 10:04:37 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using tweak class name cpw.mods.fml.common.launcher.FMLTweaker 2013-08-28 22:04:39 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.2.55.842 for Minecraft 1.6.2 loading 2013-08-28 22:04:39 [iNFO] [ForgeModLoader] Java is Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_21, running on Windows 7:amd64:6.1, installed at C:\Program Files\Java\jdk1.7.0_21\jre 2013-08-28 22:04:39 [iNFO] [ForgeModLoader] Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment.

Thanking you, Yours sincerely, Ablaze.

Thanks a lot for the quick reply guys! I solved the problem on my own. This was the problem- there is a setPotionEffect method in the Item class. That one uses a string. There is a setPotionEffect method in the ItemFood class, which uses int, int, int float. I was trying to use the latter, but java for some reason was using the former. This is how I fixed the code, for anyone else having the same problem, for later reference. fieryFood = new ItemTutorial(5000, 3, 12.0f, false).setPotionEffect(Potion.fireResistance.id, 5, 0, 0.9f); fieryFood.setUnlocalizedName("fieryFood"); Thanks a lot, Ablaze. P.S. Locking the topic.

Hello! My name is Ablaze. I'm relatively new to Forge modding, but I'm doing my best. I want to add a potion effect to a food item. If it helps, I follow Wuppy29's tutorials.
