Minecraft Forge中的从初始化到初始化错误

Question

I was making a mod and tried to add crafting recipies.
When I tried to launch it, it crashed and left a report. Can someone please tell me what I need to do to fix this?

java.lang.StringIndexOutOfBoundsException: 
String index out of range: 5 at java.lang.String.charAt(Unknown Source) at 
net.minecraft.item.crafting.CraftingManager.addRecipe(CraftingManager.java:232) at 

StringIndexOutOfBounds means: if you have a string that has a length of 4, and try to access position 5, it does not exist, and you get this problem.

"hello" > length 5 h 0 e 1 l 2 l 3 o 4

it has 5 elements. But if you try to access it at 5, "hello".charAt(5) you'll get an string index out of bounds, because index 5 does not exist.

You probaly defined your recipe wrong.

So check your recipe in CraftingManager.java:232 <-- line number

and check your documentation.

Without code, I can't help you.

EDIT

From the comments:

DiaSlab, 3), new Object[]{" "," ","XXX" those strings before the XXX need to be >equal lenth. Make them 3 spaces.
