Frost Dragon Empire Posted October 27, 2019 Posted October 27, 2019 (edited) I have a tile entity, and I need to access the villager who is standing on top of the tile, or maybe all the villagers standing on top of the tile. How can I do this? This function looks like the right one to use, just not sure what to put for the predicate. public <T extends Entity> List<T> getEntitiesWithinAABB(Class<? extends T> clazz, AxisAlignedBB aabb, @Nullable Predicate<? super T> filter) Edited October 27, 2019 by Frost Dragon Empire Quote
DavidM Posted October 28, 2019 Posted October 28, 2019 The predicate need to return true if the given Entity matches what you are looking for. In this case, it should return true if the given Entity if a villager. Quote Some tips: Spoiler Modder Support: Spoiler 1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code. 2. Always post your code. 3. Never copy and paste code. You won't learn anything from doing that. 4. Quote Programming via Eclipse's hotfixes will get you nowhere 5. Learn to use your IDE, especially the debugger. 6. Quote The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it. Support & Bug Reports: Spoiler 1. Read the EAQ before asking for help. Remember to provide the appropriate log(s). 2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

Use this one. The predicate is for determining special data about the entity for your case along as you pass AbstractVillagerEntity(or whatever the class name is) you can just simply return true.

Frost Dragon Empire Posted October 29, 2019 Author Posted October 29, 2019 (edited) I think I am miss understanding something here. This is my code: AxisAlignedBB axis = new AxisAlignedBB(pos.getX(), pos.getY(), pos.getZ(), pos.getX(), pos.getY()+3, pos.getZ()); List<Entity> villagers = world.getEntitiesWithinAABB(AbstractVillagerEntity.class, axis, entity -> true); System.out.println("Villager Count " + villagers.size()); and when I run this, it's not finding any villagers, even though they are right on top of the block. <edit> the variable pos is the block position. I check it to make sure something weird wasn't happening to the variable. Edited October 29, 2019 by Frost Dragon Empire Quote

AxisAlignedBB is a bounding box right now you are asking for a bounding box that goes from x to x, from y to y+3, and from z to z. Which is not a box it is a line. Thus on your second x and z you need to add 1. Quote VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING I will be posting 1.15.2 modding tutorials on this channel.

Frost Dragon Empire Posted October 29, 2019 Author Posted October 29, 2019 That worked, also I was digging through the spawner code, and found this works just fine. (Changing how I am doing things a little, so I may use all living entities instead of just villagers.) List<Entity> villagers = world.getEntitiesWithinAABB(LivingEntity.class, axis); Quote
