Find Entity at coordinates XYZ

[kc9zda]

Hello, I want to find an Entity at a set of coordinates specified. I need will need to access the fields of that Entity class. I am already using World.getClosestPlayer(X,Y,Z,4.0), but I don't want to access an Entity standing behind me. I have code written to try to figure out if that Entity is standing in view by comparing it to my look vector, but I don't think that the look vector would work completely. Is there some world function that finds the Entity at XYZ Coordinates and returns a reference to that Entity?

Hi

 

You can get all entities within a certain x,y,z range by defining an AxisAlignedBoundingBox and calling the function below

 

Snippet taken from EntityLiving.onLivingUpdate::

            List list = this.worldObj.getEntitiesWithinAABB(EntityItem.class, this.boundingBox.expand(1.0D, 0.0D, 1.0D));

 

You can tell if an entity is behind the player by:

1) calculating the direction vector from the player to the entity

2) calculating the dot product of this vector with the player's look vector

3) if the dot product is negative, the entity is behind the player.

 

Let us know if you need more help?

Yes that was the method I was talking about.

You can offset AABBs by the look vector so that the AABB is only in front of the player.

 

It's like f*cking magic.
