NonNullList for 1.10?


Recommended Posts



So I was updating my mod and I found that NonNullList no longer exists, is there any replacement



    public static boolean isIInvEmpty(NonNullList<ItemStack> slots) {
        for (ItemStack stack : slots) {
            if (StackUtil.isValid(stack)) {
                return false;

        return true;


and how would I find functions, such as:


because this doesnt exist for an itemstack anymore :/



Relatively new to modding.

Your post is confusing. Your title mentions 1.10 and your post says that you're updating, but you're referencing classes and methods (

Which version are you updating from and which version are you updating to?



was renamed to


. You can use MCPBot to view the current and previous names of fields and methods.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
