Aidas1000

After making 2 posts for my custom crafting table, here comes a third one. As the titles says I'm trying to animate few parts of a gui. I am not making something advanced, just some lights changing color. I tried making an mcmeta file. Seems to work only for 16x16 textures, because it squished my gui .

Oh.. Yeah... I thought it must return an item. Sorry . Everything works fine now.

[/code] The updated code: package aidas.morestuff.crafting; import aidas.morestuff.items.MItems; import net.minecraft.inventory.InventoryCrafting; import net.minecraft.item.ItemStack; import net.minecraft.item.crafting.IRecipe; import net.minecraft.world.World; import net.minecraftforge.common.ForgeHooks; public class RubySeedRecipie implements IRecipe { @Override public boolean matches(InventoryCrafting slot, World worldIn) { if(slot.getSizeInventory() != 16) return false; boolean matches = false; for(int i = 0; i < slot.getSizeInventory(); i++) { matches = slot.getStackInSlot(i) != null && slot.getStackInSlot(i).getItem() == MItems.ruby; if(!matches) break; } return matches; } @Override public ItemStack getCraftingResult(InventoryCrafting p_77572_1_) { return new ItemStack(MItems.pokeball); } @Override public int getRecipeSize() { return 16; } @Override public ItemStack getRecipeOutput() { return new ItemStack(MItems.pokeball); } @Override public ItemStack[] getRemainingItems(InventoryCrafting p_179532_1_) { return ForgeHooks.defaultRecipeGetRemainingItems(null); } }

Ok after I added the forge hook I get a different crash report net.minecraft.util.ReportedException: Updating screen events at net.minecraft.client.Minecraft.runTick(Minecraft.java:1774) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1087) ~[Minecraft.class:?] at net.minecraft.client.Minecraft.run(Minecraft.java:376) [Minecraft.class:?] at net.minecraft.client.main.Main.main(Main.java:117) [Main.class:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_31] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_31] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_31] at java.lang.reflect.Method.invoke(Method.java:483) ~[?:1.8.0_31] 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_31] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_31] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_31] at java.lang.reflect.Method.invoke(Method.java:483) ~[?:1.8.0_31] at net.minecraftforge.gradle.GradleStartCommon.launch(Unknown Source) [start/:?] at GradleStart.main(Unknown Source) [start/:?] Caused by: java.lang.NullPointerException at net.minecraftforge.common.ForgeHooks.defaultRecipeGetRemainingItems(ForgeHooks.java:715) ~[ForgeHooks.class:?] at aidas.morestuff.crafting.RubySeedRecipie.getRemainingItems(RubySeedRecipie.java:47) ~[RubySeedRecipie.class:?] at net.minecraft.item.crafting.CraftingManager.func_180303_b(CraftingManager.java:362) ~[CraftingManager.class:?] at net.minecraft.inventory.SlotCrafting.onPickupFromSlot(SlotCrafting.java:136) ~[slotCrafting.class:?] at net.minecraft.inventory.Container.slotClick(Container.java:359) ~[Container.class:?] at net.minecraft.client.multiplayer.PlayerControllerMP.windowClick(PlayerControllerMP.java:539) ~[PlayerControllerMP.class:?] at net.minecraft.client.gui.inventory.GuiContainer.handleMouseClick(GuiContainer.java:690) ~[GuiContainer.class:?] at net.minecraft.client.gui.inventory.GuiContainer.mouseClicked(GuiContainer.java:422) ~[GuiContainer.class:?] at net.minecraft.client.gui.GuiScreen.handleMouseInput(GuiScreen.java:606) ~[GuiScreen.class:?] at net.minecraft.client.gui.GuiScreen.handleInput(GuiScreen.java:572) ~[GuiScreen.class:?] at net.minecraft.client.Minecraft.runTick(Minecraft.java:1760) ~[Minecraft.class:?] ... 15 more [21:07:16] [Client thread/INFO] [sTDOUT]: [net.minecraft.init.Bootstrap:printToSYSOUT:663]: ---- Minecraft Crash Report ---- // But it works on my machine.

I might sound dumb, but how do I make the player get nothing without returning null?

@Mod http://pastebin.com/4QNrjRJR Recipe registering http://pastebin.com/5MQCgys1 And the item registration http://pastebin.com/zgdG8Yyc

I'm first registering the recipe in both client and server side and then items/blocks. Don't do that. Items/blocks should be registered in the preInit phase. Recipes should be registered in the init phase. Ok. I have placed it in the init phase, but it still crashes with the same error.
