Solved Imitating the DataValue "NoGravity"? NBT?

Hi,

I was wondering if there was a way to imitate the NoGravity data tag for entities. Example: you can make a floating hologram by doing this: /summon ArmorStand ~ ~ ~ {Invulnerable:1b,NoGravity:1b,Invisible:1b,CustomNameVisible:1b,CustomName:Test}
But I'd like to do this programmatically. I can do everything except the NoGravity option. Is there something in the CraftEntity class that would allow me to do this? I'd prefer to stay away from schedulers.

 

@ColonelHedgehog What version of CraftBukkit are you using?

 

@ColonelHedgehog
This can be achieved through editing MetaData. Try setting the entities Metadata(NoGravity,true); like so.

 

If you mean for *all* entities, I don't think you really can. The "NoGravity" tag is specific to armor stands.

The best you can do (sort of) is to apply a velocity to an entity on a scheduled task to counteract gravity- but this doesn't work well, is susceptible to lag, makes the client go out of sync, etc.

 

Oh, sorry, I posted in the wrong section.

As for the rest: I tried setting the metadata, but it didn't work.

I tried:

hologram.setMetadata("NoGravity", new FixedMetadataValue(plugin, "1b"));

And:

hologram.setMetadata("NoGravity", new FixedMetadataValue(plugin, true));

hologram is the ArmorStand.

EDIT: I fixed it. I used NMS and OBC with reflection:

Code:

Class<?> CraftArmorStand = Reflection.getOBC("entity.CraftArmorStand"); // Gets the CraftBukkit classClass<?> EntityArmorStand = Reflection.getNMSClass("EntityArmorStand"); // Gets the NMS classObject CASInstance = CraftArmorStand.cast(hologram);
Method getHandleMethod = CraftArmorStand.getMethod("getHandle");
Object handle = getHandleMethod.invoke(CASInstance);
Method setGravityMethod = EntityArmorStand.getMethod("setGravity", boolean.class);
setGravityMethod.invoke(handle, true);
