Okay, so: My mod is changing BiomeGenBase class and it crashes with different mods like Biomes O Plenty, Twilight forest... (also because they set up biomes registration in pre init and also becuse biomes registration class is instanceof BiomeGenBase): ---- Minecraft Crash Report ---- // There are four lights!

Thanks! It helped! Now i have a question a bit out of topic: Can i force coremod to launch earlier? Beacuse what i'm doing works fine with just MC, but with other mods, it crashes because it doesn't find a class that isn't edited yet...

Sorry for that maybe simple question, but i couldn't find anything on the web. How to export coremods? If i export it as normal mod (gradlew build), i doesn't work when i put it in mods folder. It works fine in eclipse, but i just can not export it out side. Thanks for answering this (maybe easy) question!

HINT: To sand multiple data between server an client you can use NBT system, that is ready to work, example: Goal: transfer using 1 packet, EntityPlayer, int, int and boolean First: let's convert player in string using UUID system (for recovery afterwards we will also need id of dimension he's in, that's first int): player.func_146094_a(player.getGameProfile()).toString() Now we need to transfer String, int, int and boolean. How to do that? - Using NBT! NBTTagCompound data = new NBTTagCompound(); data.setString("player", player.func_146094_a(player.getGameProfile()).toString()); data.setBoolean("fixed", fixed); data.setInteger("mode", mode); data.setInteger("dim", player.worldObj.provider.dimensionId); Now a general question: how to convert it in bytes? - FML did all for you: using cpw.mods.fml.common.network.ByteBufUtils.writeTag you can convert NBT into bytes: ByteBufUtils.writeTag(buf, data); Now how to read it? - I'll say only one thing about it: NBTTagCompound data = ByteBufUtils.readTag(buf); What did you learn: Using NBT, you can transfer multiple data in 1 packet. Data that you can transfer using NBT: String, byte, short, long, int, boolean, double, float, int[]... And others if you create new types of NBTTags!

Hi, i have some problems with NBTs: For some reasons they are not transfered properly in between my Item. You will see what i mean in a second: Here's my class (not all, all takes 2000 lines, so i just put here code that isn't working), with 3 methods we're interested in: setItems: public static ItemStack setItems(Map<Integer, ItemStack> map, ItemStack itemstack){ fixTags(itemstack); for(int metadata = 1; metadata < 10; metadata++){ itemstack = setToolForMeta(itemstack, map.get(metadata), metadata); } /*for(ItemStack i : map.values()){ System.out.println(i.getDisplayName()); }*/ System.out.println("Are stacks equal: " + ItemStack.areItemStacksEqual(itemstack, ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound())))); NBTTagCompound tag = itemstack.writeToNBT(new NBTTagCompound()); System.out.println("Has tag: " + tag.hasKey("tag")); System.out.println("Has ctd: " + tag.getCompoundTag("tag").hasKey("compressedtooldata")); System.out.println("Has sword tag: " + tag.getCompoundTag("tag").getCompoundTag("compressedtooldata").hasKey("sword")); System.out.println("Sword nbt: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword"))); System.out.println("Sword for meta: " + getToolFromMeta(itemstack, 1)); System.out.println("Sword name: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword")).getDisplayName()); return itemstack; } setToolForMeta: public static ItemStack setToolForMeta(ItemStack itemstack, ItemStack tool, int metadata){ if(metadata == 1){ ItemStack ret = setSword(itemstack, tool); System.out.println("Are stacks equal: " + ItemStack.areItemStacksEqual(itemstack, ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound())))); NBTTagCompound tag = itemstack.writeToNBT(new NBTTagCompound()); System.out.println("Has tag: " + tag.hasKey("tag")); System.out.println("Has ctd: " + tag.getCompoundTag("tag").hasKey("compressedtooldata")); System.out.println("Has sword tag: " + tag.getCompoundTag("tag").getCompoundTag("compressedtooldata").hasKey("sword")); System.out.println("Sword: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword"))); System.out.println("Sword for meta: " + getToolFromMeta(itemstack, 1)); System.out.println("Sword name: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword")).getDisplayName()); return ret; } if(metadata == 2) return setPickaxe(itemstack, tool); if(metadata == 3) return setShovel(itemstack, tool); if(metadata == 4) return setAxe(itemstack, tool); if(metadata == 5) return setHoe(itemstack, tool); if(metadata == 6) return set6thItem(itemstack, tool); if(metadata == 7) return set7thItem(itemstack, tool); if(metadata == return set8thItem(itemstack, tool); if(metadata == 9) return set9thItem(itemstack, tool); return itemstack; } And finally setSword: public static ItemStack setSword(ItemStack itemstack, ItemStack tool){ fixTags(itemstack); if(tool == null) return nullifieSword(itemstack); NBTTagCompound nbt = itemstack.writeToNBT(new NBTTagCompound()); tool.writeToNBT(nbt.getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword")); itemstack.readFromNBT(nbt); itemstack.setTagCompound(nbt.getCompoundTag("tag")); // System.out.println(tool.getDisplayName()); // System.out.println("Set sword: " + ItemStack.loadItemStackFromNBT(nbt.getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword")).getDisplayName()); System.out.println("Are stacks equal: " + ItemStack.areItemStacksEqual(itemstack, ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound())))); NBTTagCompound tag = itemstack.writeToNBT(new NBTTagCompound()); System.out.println("Has tag: " + tag.hasKey("tag")); System.out.println("Has ctd: " + tag.getCompoundTag("tag").hasKey("compressedtooldata")); System.out.println("Has sword tag: " + tag.getCompoundTag("tag").getCompoundTag("compressedtooldata").hasKey("sword")); System.out.println("Sword: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword"))); System.out.println("Sword name: " + ItemStack.loadItemStackFromNBT(itemstack.writeToNBT(new NBTTagCompound()).getCompoundTag("tag").getCompoundTag("compressedtooldata").getCompoundTag("sword")).getDisplayName()); return itemstack; } The problem is: the "sword" (AND ONLY THE SWORD!!!) isn't saved proper;y, how ever all others are saved: When i call setItems, with defined map, that's what i get in console: [19:51:52] [server thread/INFO] [sTDOUT]:

Making another coremod I ENCOUNTERED THE SAME PROBLEM: COREMOD LOADS SIMULATENOUSLY TO MC, AND THAT'S VERY PROBLEMATIC IF YOU WANT TO OVERHANDLE BIOME REGISTRATION FOR EXAMPLE!!!!!!

Finding ways, i know, that i can extend class, remap everything in post init, but there are still some things to patch Some that have not the best solution: loadOptions and saveOtions, but i can still save to world, but then gui will not be acessible outside of world... One that needs to be patched: runTick in MC, because MC uses "wrong" keyupdate system isKeyDown, just needs to be patched, just because it uses int PS: way to make this possible: by saving keys in int[] instead of int allows to store more keys for one Key Binding

Why do you think so? I'll have to patch at least GUIControls for that... or use events to overhandle Gui opening... But there's still some methods that will be needed to be patched.

I'm trying to rewrite vanilla key system, to make it possible to bind few keys for one action. (shift + alt + i for example)

I'm making coremod, that patches few things in GameSettings, how ever doesn't finish patching it before MC asks this class...

Ok. Now i have another problem: TileEntity isn't get properly for GUIand with wrong data: GUI: public GUIToolsCompressor(InventoryPlayer inventory, TileEntityToolsCompressor tileentity) { super(new ContainerToolsCompressor(inventory, tileentity)); toolsCompressor = tileentity; System.out.println(toolsCompressor + " " + toolsCompressor.isWorking()); this.xSize = 247; this.ySize = 248; } onBlockActivated: public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ){ if(world.isRemote){ return true; } else if(!player.isSneaking()) { TileEntityToolsCompressor te = (TileEntityToolsCompressor) world.getTileEntity(x, y, z); System.out.println(te + " " + te.isWorking()); if(te != null){ FMLNetworkHandler.openGui(player, MainToolsCompressor.instance, MainToolsCompressor.guiIdToolsCompressor, world, x, y, z); } return true; } else { return false; } } Console: [16:20:05] [server thread/INFO] [sTDOUT]: [code.elix_x.mods.toolscompressor.blocks.ToolsCompressor:onBlockActivated:61]: code.elix_x.mods.toolscompressor.blocks.TileEntityToolsCompressor@43c0a9cb true [16:20:05] [Client thread/INFO] [sTDOUT]: [code.elix_x.mods.toolscompressor.gui.GUIToolsCompressor:<init>:24]: code.elix_x.mods.toolscompressor.blocks.TileEntityToolsCompressor@75f2a654 false Why tile entity's data is different in gui???

Thanks! I know that i can fit in 256*256, but gui it self draws fine, like expected (drawTexturedModalRect(guiLeft, guiTop, 0, 0, 247, 248, 288, 288); ) EDIT: i think i figured it out: drawTexturedModalRect(x, y, u, v, width, height); x and y being coordinates of top left corner of place to place image. Must always begin with guiLeft + and guiTop + u and v being place of top left corner of image to take. MUST NEVER USE guiLeft and guiTop width and height being size of image to draw... Pretty simple. FAIL.

First of all, my gui uses more then 256*256 texture, so i needed to rewrite drawTexturedModalRect(). It's done, but now i'm having a lot of problems: None of methods are not working properly to draw texture above old place (ex: burning progress in furnace, etc), because 1) i don't unedrstand properly what does x, y, u, v, width, height means and i can't figure it out. 2) i have too big texture Also i found that if change screen size of mc, position and square changes...? I'm not sure if it must happen. Modified drawTexturedModalRect: public void drawTexturedModalRect(int x, int y, int u, int v, int width, int height, int textureWidth, int textureHeight) { float f = 1F / (float)textureWidth; float f1 = 1F / (float)textureHeight; Tessellator tessellator = Tessellator.instance; tessellator.startDrawingQuads(); tessellator.addVertexWithUV((double)(x), (double)(y + height), 0, (double)((float)(u) * f), (double)((float)(v + height) * f1)); tessellator.addVertexWithUV((double)(x + width), (double)(y + height), 0, (double)((float)(u + width) * f), (double)((float)(v + height) * f1)); tessellator.addVertexWithUV((double)(x + width), (double)(y), 0, (double)((float)(u + width) * f), (double)((float)(v) * f1)); tessellator.addVertexWithUV((double)(x), (double)(y), 0, (double)((float)(u) * f), (double)((float)(v) * f1)); tessellator.draw(); } and it calling code in drawGuiContainerBackgroundLayer drawTexturedModalRect(guiLeft + 154, guiTop + 83, 13, 13, guiLeft + 248, guiTop + 0, 288, 288); My texture: Help me please!

I found an error that's fine now: one of items was hoe, that doesn't have attack damage value...

I have this thing repeated 9 the same way times and it crashes randomly on one of blocks.

Crash report please. I'm sure it crashes not on stack.stacksize--;

So the problem is: When i hit entity with my item, before hurt is performed (using AttackEntityEvent) if player is holding my item, it scans 9 items "inside"n this item and chooses one with the biggest amount of damage.

Not exactly, i made it different way, i just changed this: if(event.getSide() == Side.CLIENT) FMLCommonHandler.instance().bus().register(new BTAMKeyRegistry()); And now it works fine... MORE THEN THAT: Code in BTAMKeyRegistry still works without packets...

How ever if remove this code that i need packets for, it still crashes on same thing.

Also i found out this: Liquid automatically turns in another block even when placed by me and updated? Reading through BlockDynamicLiquid and BlockStaticLiquid, if found methods, that are responsible for making in flow, where to detect another state of liquid, getIdFromBlock(this) - 1 is used, its private method, and it cannot be overrided... STUPID MINECRAFT!!!!! JUST BY REGISTERING STILL LIQUID AFTER FLOWING MAKES IT WORK PROPERLY!!! FACEPALM

Yes: Injecting existing block and item data into this server instance [10:32:31] [server thread/INFO]: Injecting new block and item data into this server instance.
