I'm trying to add a recipe to my mod, using this line of code:

GameRegistry.addRecipe(new ItemStack(ModItems.mapleLeaf, 10), " s ", "sss", "s", 's', new ItemStack(Items.stick));

I expect that to create a recipe like this:

 

 

But that doesn't work. By chance I discovered that it creates this recipe instead:

 

 

 

What am I doing wrong here?

I'm afraid the images aren't loading for me. Could you describe the problem?

Instead of creating this recipe:

./.
///
./.

It creates this:

...
/.. 
...

 

Where / is a stick, and . is nothing.

Try adding the spaces to the last "s"

" s "
"sss"
" s "
//INSTEAD OF
" s "
"sss"
"s"

Thanks, that works.

 

I have another question, why can't I use " instead of ' in the last bit?

I haven't looked at it, but I'd assume that's just the way of differentiating between the values and the recipe itself (probably with instanceof checks against char and String respectively).

 

If you mean what the difference between double and single quotes is, that is a Java question.

doing

" s "
"sss"
"s"

minecraft won't understand in which slot he needs to place last s: in 1st or 2nd or 3rd. If you are using grid 3*3 in all 3 lines must be 3 characters!!! using grid 3 by 2, you must have 2 characters in each line... otherwise minecraft doesn't understand where to put last stick.
