    • Well, too bad. 1.12.2 is not supported on the forum. Nobody on the forum will help you with 1.12.2 forge. Sorry *shrugs*
    • Howdy, all. I've been working on a custom, 4x4 crafting table in 1.12.2. The code seems to be alright, but I keep getting a NullPointerException when I try to open it. Here's the error: [20:43:23] [main/FATAL]: Error executing task java.util.concurrent.ExecutionException: java.lang.NullPointerException     at java.util.concurrent.FutureTask.report(Unknown Source) ~[?:1.8.0_231]     at java.util.concurrent.FutureTask.get(Unknown Source) ~[?:1.8.0_231]     at net.minecraft.util.Util.runTask(Util.java:54) [Util.class:?]     at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1161) [Minecraft.class:?]     at net.minecraft.client.Minecraft.run(Minecraft.java:436) [Minecraft.class:?]     at net.minecraft.client.main.Main.main(Main.java:118) [Main.class:?]     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_231]     at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_231]     at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_231]     at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_231]     at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?]     at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?]     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_231]     at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_231]     at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_231]     at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_231]     at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:97) [start/:?]     at GradleStart.main(GradleStart.java:26) [start/:?] Caused by: java.lang.NullPointerException     at com.mineundermatter.survivalessentials.gui.crynyx_crafting_table.ContainerCrynyxCraftingTable.updateMatrix(ContainerCrynyxCraftingTable.java:69) ~[ContainerCrynyxCraftingTable.class:?]     at com.mineundermatter.survivalessentials.gui.crynyx_crafting_table.ContainerCrynyxCraftingTable.<init>(ContainerCrynyxCraftingTable.java:41) ~[ContainerCrynyxCraftingTable.class:?]     at com.mineundermatter.survivalessentials.gui.crynyx_crafting_table.GuiCrynyxCraftingTable.<init>(GuiCrynyxCraftingTable.java:18) ~[GuiCrynyxCraftingTable.class:?]     at com.mineundermatter.survivalessentials.gui.GuiHandler.getClientGuiElement(GuiHandler.java:74) ~[GuiHandler.class:?]     at net.minecraftforge.fml.common.network.NetworkRegistry.getLocalGuiContainer(NetworkRegistry.java:277) ~[NetworkRegistry.class:?]     at net.minecraftforge.fml.common.network.internal.FMLNetworkHandler.openGui(FMLNetworkHandler.java:110) ~[FMLNetworkHandler.class:?]     at net.minecraft.entity.player.EntityPlayer.openGui(EntityPlayer.java:2776) ~[EntityPlayer.class:?]     at net.minecraftforge.fml.common.network.internal.OpenGuiHandler.process(OpenGuiHandler.java:50) ~[OpenGuiHandler.class:?]     at net.minecraftforge.fml.common.network.internal.OpenGuiHandler.lambda$channelRead0$0(OpenGuiHandler.java:43) ~[OpenGuiHandler.class:?]     at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) ~[?:1.8.0_231]     at java.util.concurrent.FutureTask.run(Unknown Source) ~[?:1.8.0_231]     at net.minecraft.util.Util.runTask(Util.java:53) ~[Util.class:?]     ... 15 more       Here's the Github for my project: https://github.com/frankcav/SurvivalEssentials-1.12.2 Here's the block class: https://github.com/frankcav/SurvivalEssentials-1.12.2/blob/master/src/main/java/com/mineundermatter/survivalessentials/block/BlockCrynyxCraftingTable.java The tileentity class: https://github.com/frankcav/SurvivalEssentials-1.12.2/blob/master/src/main/java/com/mineundermatter/survivalessentials/tileentity/TileEntityCrynyxCraftingTable.java The GUI class: https://github.com/frankcav/SurvivalEssentials-1.12.2/blob/master/src/main/java/com/mineundermatter/survivalessentials/gui/crynyx_crafting_table/GuiCrynyxCraftingTable.java The container class: https://github.com/frankcav/SurvivalEssentials-1.12.2/blob/master/src/main/java/com/mineundermatter/survivalessentials/gui/crynyx_crafting_table/ContainerCrynyxCraftingTable.java GuiHandler class: https://github.com/frankcav/SurvivalEssentials-1.12.2/blob/master/src/main/java/com/mineundermatter/survivalessentials/gui/GuiHandler.java   The first error is in my updateMatrix function in the container class. If I comment out the call to updateMatrix in the constructor, I'm able to open the table but trying to leave it or put in an item crashes the game. I'm not sure what other information I can give, so please ask questions... I'd appreciate any help. I've made a custom duel furnace, as well as custom regular furnace, but I can't seem to solve this problem.
    • IT WORKED!!! I tried it after i uninstalled winRar and it downloaded nicely. Thanks!
    • DONT REPLY WITH WE DONT SUPORT 1.12.2 it’s basically the same just HELP!   Please help me with this! Here is the log file: https://ufile.io/emphlfn5   It says Exception in thread "main"
    • Ok thanks! I think its because i have a jar file extractor so i think that makes it so that it extracts the file instead of running it. I'll try it and see if it works.
