[1.8]Using aabb to give near entitys a potion effect.

[Looke81]

Hey I'm making an entity that gives near entitys a potion effect and i know i have to use getEntitiesWithinAABBExcludingEntity but i don't know how to use aabb and i cant find anything that explains it. So basically how do you use aabb to get nearby entitys to my entity?

AxisAlignedBB takes 6 arguments: minX/Y/Z, maxX/Y/Z. Easiest way to use it for an area surrounding an entity is getEntityBoundingBox().expand(dx, dy, dz) where dX/Y/Z are the amount you want to expand along that axis (it expands in both directions, so 8.0D actually adds 16.0D to the total dimensions).

 

this.getEntityBoundingBox().expand(8.0D, 4.0D, 8.0D) // gets all entities around this entity within 8 blocks, but only 4 along the y axis

ok so now i know how to use AxisAlignedBB  but that returns a list so how do I get the entity out of the list and manipulate it?

With Java. If you don't already know it, learn it. Google and Java documentation / tutorials are your friend.
