Thanks for the suggestion. You were partly correct. I had the recipe registering in the initialization method, I moved it to the preInitialization after the blocks are registered and now it's working.

I've been having an issue with trying to create a custom recipe using items that I created. I have made 1 block and 1 item. Neither one of them can be used in a recipe as a component or Minecraft won't even load. Now if I make either item the item produced by the recipe then Minecraft will load but crash once the recipe is put into the crafting bench. The best I've come up with is that it is some sort of rendering issue from the crash reports and error messages. I can't find any information on anyone else having this issue most guides only talk about making a crafting recipe with existing items. I have no clue what code would be relevant because I don't understand the nature of the issue. This is the line that creates the recipe. If I change my mod block to anything in Minecraft already, it works. GameRegistry.addRecipe(new ItemStack(BlockHandler.exchanger), "##", "##", '#', Blocks.cobblestone); Here is the error message when I tried to craft my mod block using 4 pieces of cobblestone: net.minecraft.util.ReportedException: Rendering item at net.minecraft.client.renderer.EntityRenderer.updateCameraAndRender(EntityRenderer.java:1164) ~[EntityRenderer.class:?] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1114) ~[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_45] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_45] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_45] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_45] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.11.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.11.jar:?] at net.minecraftforge.gradle.GradleStartCommon.launch(Unknown Source) [start/:?] at GradleStart.main(Unknown Source) [start/:?] Caused by: java.lang.NullPointerException at net.minecraft.item.ItemStack.getMetadata(ItemStack.java:280) ~[itemStack.class:?] at net.minecraft.client.renderer.ItemModelMesher.getMetadata(ItemModelMesher.java:70) ~[itemModelMesher.class:?] at net.minecraft.client.renderer.ItemModelMesher.getItemModel(ItemModelMesher.java:43) ~[itemModelMesher.class:?] at net.minecraft.client.renderer.entity.RenderItem.renderItemIntoGUI(RenderItem.java:363) ~[RenderItem.class:?] at net.minecraft.client.renderer.entity.RenderItem.renderItemAndEffectIntoGUI(RenderItem.java:414) ~[RenderItem.class:?] at net.minecraft.client.gui.inventory.GuiContainer.drawSlot(GuiContainer.java:293) ~[GuiContainer.class:?] at net.minecraft.client.gui.inventory.GuiContainer.drawScreen(GuiContainer.java:116) ~[GuiContainer.class:?] at net.minecraftforge.client.ForgeHooksClient.drawScreen(ForgeHooksClient.java:462) ~[ForgeHooksClient.class:?] at net.minecraft.client.renderer.EntityRenderer.updateCameraAndRender(EntityRenderer.java:1134) ~[EntityRenderer.class:?] ... 11 more [00:19:03] [Client thread/INFO] [sTDOUT]: [net.minecraft.init.Bootstrap:printToSYSOUT:663]: ---- Minecraft Crash Report ---- // Why did you do that?

Will do, thanks for all the help.

Thank you for the quick response. But I still don't understand how figuring out what type the recipe is will allow me to access the object[] that holds the ingredients. Could you please elaborate. while(recIterator.hasNext()){ if(recIterator.next() instanceof ShapedRecipes){ } } I pasted my simple code to find out what type it is but I don't know how to proceed further and get the array.

I've been trying to figure out a way to obtain the Object array that stores the items in a recipe for days now. I really just need some help figuring out how to access the arrays. I've attempted to see how NEI gets the ingredients but it seems to be beyond my understanding. I understand how to get the recipe list and all that just not how to get the object arrays that describe what the recipe actually is. There's a method that gives the output of a recipe but not the input. How would I get the input?
