Is there an object which contains the World, Location and Direction information?

KieronWiltshire · May 4, 2015, 1:43am

Bukkit stores direction, location and the world all in one class.
Is there a similar object within the API I could use, or will I have to utilize my own?

This doesn’t store the Direction or World.

FerusGrim · May 4, 2015, 1:52am

Check again, buddy. Location includes both the Extent and the Vector(s).

boformer · May 4, 2015, 2:04am

It does not store the direction (rotation), though.

FerusGrim · May 4, 2015, 2:11am

Vector3d IS rotation.

That’s not what I want.

FerusGrim · May 4, 2015, 2:15am

I’m not sure what it is you want.

From the Location class, you can get the World (Extent) and the Direction (Vector3d). What am I missing, here?

KieronWiltshire · May 4, 2015, 2:17am

No, you get the World (Extent) and the X, Y, Z coordinates. You do not get the direction…

mmonkey · May 4, 2015, 2:18am

Locations don’t have a direction, however Players do, player.getRotation()

FerusGrim · May 4, 2015, 2:19am

Vector3d is not created by Sponge. The way they utilize it, however, gives the direction. Read the Javadocs, in my last post.

github.com

SpongePowered/SpongeAPI/blob/api-10/src/main/java/org/spongepowered/api/entity/Entity.java#L93


      
          
          /**
           * Gets the {@link EntityType}.
           *
           * @return The type
           */
          EntityType<?> type();
          
          /**
           * Creates an {@link EntitySnapshot}.
           *
           * @return The snapshot
           */
          EntitySnapshot createSnapshot();
          
          @Override
          Entity copy();
          
          /**
           * Creates an {@link EntityArchetype} for use with {@link Schematic}s.
           *

Locations can have a direction/rotation.

Boomshroom · May 4, 2015, 2:21am

Yes, Vector3d can represent direction, but in the Location class, it doesn’t.

FerusGrim · May 4, 2015, 2:24am

Then, in the Location class, what does it represent? You can get the block location, but according to the javadocs with Vector3d, it just says Get the underlying location, which, admittedly, doesn’t explain much.

boformer · May 4, 2015, 2:27am

The vector represents the x y z coords, the extent is the world.

KieronWiltshire · May 4, 2015, 2:30am

See…

@FerusGrim why did you block me on skype dude? I wasn’t being harsh, you was telling me to read the docs which I clearly had done. I understand the Entity class holds the information, but that’s not what I’m looking for…

TheAwesomeGem · May 4, 2015, 2:30am

Try using Direction.getClosest(entity.getRotation()) to get the closest horizontal direction and to convert it back to Vector3, use toVector3d(). Not tested.

You can also use Quaternoid but I highly doubt that’s what you want.

KieronWiltshire · May 4, 2015, 2:32am

Lmao, that’s not even close. The reason I want it for is probably stupid.

I want one class, maybe called ‘SpawnLocation’ which stores the World UUID, Location coordinates and the Direction values. I want it so I can just go ahead and Serialize the SpawnLocation object, as well as instantiate it from the serialization automagically using Gson. haha, that’s all I want it for

boformer · May 4, 2015, 2:32am

Back to your question: Just create your own class that stores the location and the rotation.

KieronWiltshire · May 4, 2015, 2:37am

Okay, I really wish sponge stored this :’(

Zidane · May 4, 2015, 2:56am

What you are wanting is typically thought of as Transform.

Transform would comprise the Location, Rotation (Direction or Quaternion or Vector3d or etc) and sometimes a scale.

I may consider adding something like it to the API for entities.
