It all works after moving to forge Gradle.

No, I'm using latest for 1.6.4 I believe. I'm out right now so I can confirm that when I get home in about an hour and a half.

I'm not trying to obfuscate anything from CoFHCore. and the classes arent in my mod. But my classes that are derived FROM those classes aren't being obfuscated correctly.

I'm basing a mod around Thermal Expansion and I extend a couple classes from CoFHCore. I don't know if it is intended or not, but classes that are derived from those CoFHCore classes (which in turn are derived from vanilla Minecraft classes (ItemBlock, and TileEntity specifically) cause odd errors where they don't obfuscate. I tried not extending the class that was the easiest to reimplement (one method) and it worked until I ran into a case where the other extended class was used (the worldObj pointer) and it turns out that class wasn't obfuscated. Is this a bug, its it intended, or did I just not set up my development environment properly? edit: I accidentally posted here instead of modder support, sorry. can a moderator move this thread please?

Got it all sorted, thanks!

It is running many many times.

It is supposed to be 20 levels. But it takes how many it feels like. Like if i have 10s of thousands it will go wild with them. Or if I have 21 it will take all 21.

I got it working thanks so much! Just one thing. using player.addExperienceLevel(-20); seems to take away a much larger chunk of experienced than I'd think it would.

Okay its starting to make sense. And after registering my packet handler in my @NetworkMod I should be good to go correct? I'll try this out when I get home.

So I send a packet to the server, and then in the PacketHandler I have it call my tileentity.addItemStacktoSlot()? So the handler would be like: If you get an itementity in a packet, do this If you get an integer in a packet, do this EDIT: I've been looking around again and found this example: https://github.com/dvd604/Xperium/blob/master/net/dvd/xperium/server/XperiumPacketHandler.java So I have two channels, if it comes in on say "rpglevel_lus" do the stuff for the TileEntity and if it comes in on "rpglevel_xpl" do the stuff to the player. So I'd send two packets. One being a TileEntityData packet and the other being a CustomPayload and have it parse the integer data from there and apply it to the player?

I figured that was the problem. I read the article on the wiki about sending packets, but still don't quite get it. Mind maybe pointing me in the right direction on how to do that? I get how to send like integers and bytes. But it doesn't really explain like how do I send an ItemStack and how does it know. Or how do I send the experience level and how do I tell it what that is? Custom packets? I don't know I feel in over my head with this one.

Basically my problem is this: The server doesn't know that there is a new item in the custom GUI slot. If I try to take it, it disappears. I don't know why, or how to fix it. I've spend countless hours googling and everything and can't figure this out. Help would be greatly appreciated. GUI http://pastebin.com/QNEEK9HA GUIHandler http://pastebin.com/LduXKXsv TileEntity http://pastebin.com/UcCYqp66 Basically this: Click Button -> New Item Appears -> Try to take item -> Item Disappears! ->

Okay, it is still more or less happening. I even scrapped it all and followed the tutorial from the wiki to the tee. EDIT: I know what it is. My buttons need to send the changes to the server, but how do I do that?

Thanks, I ended up figuring that out. One last problem that is holding me up. I know it has something to with either sync, or nbt (or both i suppose). When I get an item out of my custom block/tileentity it does not save that item in my inventory, nor does it save the experience I take from the player (also it always seems to set it to 11 no matter how much you have). edit: also nbt does not seem to be saving LevelUpStationGUI.java package us.xvicario.rpglevel;

I was just about to say I had figured that out, thanks! Edit: I seem to get a nullpointer if (event.entityPlayer.getItemInUse().getItem() instanceof ItemPickaxe ) { //ItemPickaxe itemInUsePickaxe = (ItemPickaxe)itemInUse.getItem(); ((ItemPickaxe)event.entityPlayer.getItemInUse().getItem()).efficiencyOnProperMaterial = (float) (((ItemPickaxe)event.entityPlayer.getItemInUse().getItem()).efficiencyOnProperMaterial * 3.0); System.out.printf("RUNNING"); }

Right now my code is more or less: class { playerInteractEvent { if item is this { do this; } } } but how do I call it? I have an instance made in my main mod class.

I was wondering how I'd detect if a player is using a pickaxe or something of the like. I know how to do it (getItemInUse()) but how would I go about detecting it. Like some kind of listener? Also I know how to use the player interact event, but how do I have it detect that?

I was using an unobfuscated version. Thanks...
