EnumFacing problem

Recommended Posts

So, in 1.7.10 before you could do

ForgeDirection.OPPOSITES

But now you cant, is there an equivalent to this?

 

I also found that you cant do 

ForgeDirection.VALID_DIRECTIONS

Was this removed?

 

Thanks for any help in advance.

P.S. I have looked in the docs but I couldn't find anything about this. Sorry if I just being stupid and didn't see it.

Use EnumFacing#getOpposite to get the opposite facing.

 

Use the EnumFacing.values method or the EnumFacing.VALUES array to get all EnumFacing values.

Can I do EnumFacing.getOpposite, or does it have to be a variable that is a EnumFacing?

I am trying to make something like this

EnumFacing invertedSide = ForgeDirection.VALID_DIRECTION[ForgeDirection.OPPOSITE[direction.ordinal]];

but for 1.10 

 

Actually I believe I fixed it and created something that works!

 

Here's the code if someone is looking for the same thing

EnumFacing invertedSide = EnumFacing.VALUES[direction.getOpposite().ordinal()];

EnumFacing#getOpposite already returns an EnumFacing, you're getting its ordinal and then looking it up in the EnumFacing.VALUES array to get the same EnumFacing. You don't need to use the EnumFacing.VALUES array here at all.

 

The indexes of EnumFacing.VALUES are the ones returned by EnumFacing#getIndex, not the ones returned by Enum#ordinal. These happen to be the same, but it's more correct to use the same indexes that are used to populate the array.

 

Use EnumFacing.getFront to get an EnumFacing by its index rather than using the EnumFacing.VALUES array directly.

Thanks! this really helped.

 

I'm very new the 1.10 coding I'm more used to 1.7.10 ^_^

 

 

Also when you say that do you mean that 

EnumFacing.getFront(direction.getOpposite().ordinal())

Would do the same thing?

I recommend right-clicking on "EnumFacing" in your code and then using the context menu to jump into the class so you can read it. That'll answer most of your questions.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

That would work, but EnumFacing.getFront uses the same indexes as EnumFacing.VALUES (because it uses EnumFacing.VALUES), i.e. EnumFacing#getIndex rather than Enum#ordinal.

 

There's also no need to use any index here, you already have the EnumFacing returned by EnumFacing#getOpposite.
