I understand that. I'm sort of in a time crunch, so I figured going for tutorials would be the fastest way, for now. In the future/now I'll study more on java

I'm starting to learn Java, I made the mistake of going to modding tutorials first

Oh okay. So I rearranged it like this: if (this.canSmeltItem()) { if (this.smeltTime >= this.maxSmeltTime) { return; } The bug occurs, but its under the if statement canSmeltItem

Okay, I inserted the code: private void trySmeltItem(){ if (this.smeltTime >= this.maxSmeltTime) { return; } ... And the bug still remains :-/

How can I check that in the trySmeltItem if there's no boolean? I thought I already checked that with boolean isItemValid method

Yes, sorry I forgot to link my GitHub. Here's the link: https://github.com/SpookyBarca/Metallurgy All my Grinder files are in the same package.

Thank you! I got the onBlockActivated method functioning correctly. Now I just have two smelting bugs... it instantly smelts items, even when there's no fuel

Hi, I've recently finished the classes for my BlockGrinder, but onBlockActivated seems to not be firing when I right-click the block. When I right-click it, absolutely nothing happens. Here's the code: //When right-clicked @Override public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) { if(worldIn.isRemote) { return true; } final TileEntity tileentity = worldIn.getTileEntity(pos); if (tileentity instanceof TileGrinder) { playerIn.openGui(Main.instance, ModGuiHandler.MOD_GRINDER, worldIn, pos.getX(), pos.getY(), pos.getZ()); playerIn.addStat(StatList.FURNACE_INTERACTION); } return true; } I used the BlockFurnace class as reference for this method, but it doesn't open the GUI nor make the player right-click animation for the block

Hi, I've recently been working on my mod for Minecraft, I was able to run the Client on Eclipse up until recently when I keep getting this crash: xception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl64 in java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at org.lwjgl.Sys$1.run(Sys.java:72) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.Sys.doLoadLibrary(Sys.java:66) at org.lwjgl.Sys.loadLibrary(Sys.java:87) at org.lwjgl.Sys.<clinit>(Sys.java:117) at net.minecraft.client.Minecraft.getSystemTime(Minecraft.java:3159) at net.minecraft.client.main.Main.main(Main.java:42) Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release I've tried to designate the native build location to my lwjgl-2.9.4-nightly.jar and similar jars for my native library location in the JRE System Library, but no solutions were made.

Hi, My Minecraft client keeps crashing every time I try to open up my Grinder block. I assume it's a Container GUI bug, but I don't know why the NPE is throwing Ticking Player .

Hi, I have a block that has a Custom Gui, but every time I right-click the block it won't appear. I know that the TileEntities are working because I wrote a debug line that "checks" if it's working. This is the error that's shown in the console when I right-click: [06:37:34] [Server thread/FATAL] [minecraft/MinecraftServer]: Error executing task java.util.concurrent.ExecutionException: java.lang.NullPointerException This is the onBlockActivated boolean in my Block: //BLOCK RIGHT-CLICKED (Opens GUI and Debug) @Override public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, EnumFacing side, float hitX, float hitY, float hitZ) { if (!world.isRemote) { //Sends a message in chat stating "Grinder Clicked" player.sendMessage(new TextComponentString("Grinder Clicked")); //Opens GUI player.openGui(Main.instance, ModGuiHandler.GRINDER, world, pos.getX(), pos.getY(), pos.getZ()); } return true; } I've also tried putting player.openGui outside of the if function, but that results in a crash. The ModGuiHandler is registered correctly as well, for NetworkRegistry.INSTANCE. Additional Info: I followed ShadowFacts tutorial for onBlockActivated Any help is appreciated, thank you.

Fixed! I'm getting no deprecated error. However, I'm still getting the "TileEntityGrinder is missing a mapping!" bug. I'm unsure how to create a mapping for the registry and TileEntity...

None of them show how to register a TileEntity for displaying GUI

Hello! So I'm trying to register my TileEntity for my Block Class in order to get the custom GUI showing. I tried using the registerTileEntity, with the name and ResourceLocation, but it's deprecated. I'm unsure how to work around this issue to help register my TileEntity... My GitHub: https://github.com/SpookyBarca/MetallurgyMod Thank you!
