Looks like right here https://github.com/SgtPunishment/Soul-Shards-Reborn/blob/master/src/main/java/moze_intel/ssr/utils/Utils.java#L74 is where the shards tier levels up, it also looks like it can return the same tier as it was before, so you'd need to do a check to see if the previous tier is higher than the current route.

Thank you very much, I didn't realize it was something so simple, like I said I don't have a lot of experience with netty but I have done a bit in the past and i used get and set int with no problems so i assumed that was the correct way to do things.

Hey everyone, I have a question about an issue I'm having with netty, I've used it before and this is the first time I've ever encountered a bug quite like this.

Some help would be greatly appreciated, and if I've made a dumb mistake that I'm just blind to then I apologize but I really can't see one.

This is an issue with the newest version of java (1.8.0_20) I've confirmed that it's the update as Forge works with Java 8 update 11.

This seems to be an issue with Java 1.8.0_20, I suggest uninstalling it and downgrading to 1.8.0_11, you can find older versions of java here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html

One idea I had was to hash the players names (I dont remember if 1.7.2 and/or 1.7.10 use hash values for players or if thats 1.8+, if it's in 1.7.2 then use minecrafts hash value) and somehow translate that into a set of coordinates or like a grid location and rather than having separate instances entirely give each player a portion of a dimension. I don't know if this is exactly what OP needed but in my case this would work as I'd only need a small area for my dimensions anyways, but it has to be a separate dimension as it fits my mod thematically. EDIT: When I say hash I don't really mean like the String.hash function (that isn't the exact name but close enough, I can't remember off the top of my head) but rather like an MD5 sum or something along those lines because it makes life a lot easier if all the "hashes" are the same length which isn't always the case with the hash function. The downside with using something like an MD5 is that is returns I believe a 128 bit number. Which is two longs worth of integer data, AKA very large. So it'd need to be truncated a lot and it becomes a mess. So that wouldn't really work either, hence me not getting any further with the idea EDIT 2: I just reread the post and realized the OP already had this idea, I didn't see the post before though haha, oh well.

I'm pretty sure Vswe (author of Steve's Carts) has a tutorial explaining what you're looking for, he did a sort of modding course a while back and I remember watching it. https://www.youtube.com/user/VsweGoesMinecraft/videos they're really useful tutorials as well.

I've gone ahead and written the recipe class you need, you're free to use it if you want. It will only allow the exact recipe to work and not the mirrored version. To add the recipe using this class you just need to call CraftingManager.getInstance().getRecipeList().add(mirrorlessShapedRecipeInstance); import net.minecraft.inventory.InventoryCrafting; import net.minecraft.item.ItemStack; import net.minecraft.item.crafting.IRecipe; import net.minecraft.world.World; public class MirrorlessShapedRecipe implements IRecipe { private final ItemStack[] recipe; private final ItemStack output; public MirrorlessShapedRecipe(ItemStack output, ItemStack[] recipe){ this.recipe = recipe; this.output = output; } @Override public boolean matches(InventoryCrafting p_77569_1_, World p_77569_2_) { for(int y = 0; y < 3; ++y){ for(int x = 0; x < 3; ++x){ ItemStack itemInSlot = p_77569_1_.getStackInRowAndColumn(x, y); ItemStack recipeSlot = recipe[y * 3 + x]; if(itemInSlot != null || recipeSlot != null) { if ((itemInSlot == null && recipeSlot != null) || (itemInSlot != null && recipeSlot == null)) { return false; } if (itemInSlot.getItem() != recipeSlot.getItem()) { return false; } if(recipeSlot.getItemDamage() != Short.MAX_VALUE && recipeSlot.getItemDamage() != itemInSlot.getItemDamage()){ return false; } } } } return true; } @Override public ItemStack getCraftingResult(InventoryCrafting p_77572_1_) { return output; } @Override public int getRecipeSize() { return 9; } @Override public ItemStack getRecipeOutput() { return output; } }

You'll need to make a class similar to vanilla's ShapedRecipes, I can't post the code here as it's not legal to post vanilla minecraft code but I believe function at line 61 is where the mirror checking happens, all you need to do is loop through the itemstacks in the inventoryCrafting provided by the matches function and make sure that all the slots are equal to the itemstacks in the recipe and if they are the recipe matches, if not then the recipe is different.

It looks like you need to offset your models render positions by +1 in y and either +1 or -1 in x or z (I can't tell from the image) You can do this in your GL11.glTranslated or GL11.glTranslatef call.

It isn't necessary to make your own IRecipe class, just instantiate a ShapedRecipes with the parameters (3, 3, new ItemStack[]{new ItemStack(Blocks.cobblestone), new ItemStack(Blocks.planks), new ItemStack(Blocks.planks), null, , new ItemStack(Items.stick), null, , new ItemStack(Items.stick), null}, new ItemStack(ModTools.SWWPickaxe, 1)) The array to crafting table looks like this: 012 345 678 Where the index represents the slot in a crafting table. Then to register your recipes do CraftingManager.getInstance().getRecipeList().add(theShapedRecipesInstance); I wrote my own mod to add custom recipes to minecraft and this is how i register the recipes. https://github.com/xandayn/Personalized-Recipes/blob/master/java/common/xandayn/personalrecipes/recipe/handlers/ShapedRecipeHandler.java#L38 ShapedRecipes is in the net.minecraft.item.crafting package. Sorry I actually was incorrect, you do need to make a custom IRecipe, I misunderstood the question when I reread it I realized what you were asking.

I'd like to mention in advance that I don't have a solution to your issue, I'm actually looking for this solution as well and have been unable to find it, I thought it'd be wasteful to create a new thread. Did you ever find a solution or are you still searching?

I spent several hours trying to figure it out to no avail so I've kinda given up on it. As for Novas comment, I dont really know what you mean by that, on windows you just run the batch file and if youre on linux/mac you open terminal and you run the command ./gradlew and it will install everything for you. That's a reply I received about the same issue, so if you're wanting to develop you just need to use 964. I don't really like the new setup as I cant access vanilla source or forge source, but oh well. It was really nice to see how things worked.

I also have the same exact issue. The way I had to get around it is by using the new ForgeGradle thing following this http://www.minecraftforge.net/forum/index.php/topic,14048.0.html guide. The download for Gradle is the latest build.

This isn't the right area to be posting this, but the issue is that you have conflicting item IDs, id 500 is being used by two mods, LotsOMobsMobHeads and The furniture mod, to fix this go into your configs, %AppData%/Roaming/.minecraft/config and there should be a file for those mods, change one of the mod's block ids from 500 to something else.

I dont know if I should start a new post or not, but I am actually having a problem on linux installing the src for mod development, here is the terminal output, Im a noob with linux and cant figure out the issue. I guess I should mention I'm trying to use Forge 9.11.1.953 and I'm on Linux Mint 16 ================ Forge ModLoader Setup Start =================== Checking MCP zip (may take time to download) Downloaded mcp8.11.zip Extracting MCP to '/home/matthew/Development/forge/mcp' Setting up MCP Patching commands.py patching file commands.py Commands patch applied successfully Copying FML conf Creating Repackaged data Creating re-packaged srg Creating re-packaged exc Creating re-packaged MCP patches Fixing MCP Workspace Traceback (most recent call last): File "install.py", line 76, in <module> decompile=options.decompile, gen_conf=False) File "install.py", line 17, in fml_main disable_assets=disable_assets) File "/home/matthew/Development/forge/fml/fml.py", line 1013, in decompile_minecraft pre_decompile(mcp_dir, fml_dir, disable_assets=disable_assets) File "/home/matthew/Development/forge/fml/fml.py", line 1061, in pre_decompile download_minecraft(mcp_dir, fml_dir) File "/home/matthew/Development/forge/fml/fml.py", line 1125, in download_minecraft failed = download_libraries(mcp_dir, version_json['libraries'], mc_info['natives_dir']) or failed File "/home/matthew/Development/forge/fml/fml.py", line 1181, in download_libraries headers = get_headers(url) File "/home/matthew/Development/forge/fml/fml.py", line 173, in get_headers response = urllib2.urlopen(HeadRequest(url)) File "/usr/lib/python2.7/urllib2.py", line 127, in urlopen return _opener.open(url, data, timeout) File "/usr/lib/python2.7/urllib2.py", line 410, in open response = meth(req, response) File "/usr/lib/python2.7/urllib2.py", line 523, in http_response 'http', request, response, code, msg, hdrs) File "/usr/lib/python2.7/urllib2.py", line 448, in error return self._call_chain(*args) File "/usr/lib/python2.7/urllib2.py", line 382, in _call_chain result = func(*args) File "/usr/lib/python2.7/urllib2.py", line 531, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 403: Forbidden

This also has been happening to me, I think there's a bug with forge somewhere, minecraft recently updated and changed a lot of the assets and I think that forge may trying to download them. That said I've no idea if this is the case, just a possibility.

Thanks for the reply, so I did what you suggested and put a break in to check what we'd see, and the ItemStack array is the correct size.

Hey, I've been stuck on a bug for a few days here and was wondering if anyone had any ideas. EDIT: I've made a Git for my project, if that's easier to see https://github.com/xandayn/StorageCraft EDIT2: I ended up just rewriting all the code for the diamond chest and now it works, never found out the exact issue of the bug though. EDIT3: So looking through my old code and comparing to my new code I realized my mistake, in the GuiHandler class I'm checking for a TileEntityGoldChest where I should be checking for a TileEntityDiamondChest, just thought I'd make that note incase anyone was having a similar issue.

I'm not sending any custom packets currently, I think I must be overlooking something but I can't find the issue to save my life, I'd really appreciate a little bit of help.
