I found out that deprecated does not mean do not use. Deprecated rather means more like "i'd rather you not use it but if you have to go then go ahead."

 

In my code I have a block which has multi textures and FACING so orientation matters. One of the functions there      getStateFromMeta(int meta) is marked as deprecated.

 

@Deprecated

    public IBlockState getStateFromMeta(int meta)

    {

        return this.getDefaultState();

    }

 

Now if you don't use this function the block resets position every time you reload the game so in this case is deprecated but YOU HAVE TO USE IT. So what do I do? I use it. There's no other way

 

Point is if it says deprecated is because original MC team are trying to move away from this function so expect it to go away in the future but doesn't mean you can't use it now.

 

Makes sense, but if it's going to go away in the future, isn't it better to avoid using it before your code gets so dependent on it that it requires a complete rewrite to make it compliant to the new changes?

Mojang uses @Deprecated to mark methods you, as a modder, shouldn't call yourself but rather another version e.g. one in

IBlockState

. You are still able to override those methods.
