CMDHELPER-2885 - Reported by CyaNox

The following code:
{code:title=MobSpawning.ms}
export('mobspawning.mobs.hostile', array('WITCH', 'CREEPER', 'SKELETON', 'SPIDER', 'ZOMBIE', 'SLIME', 'GHAST', 'PIG_ZOMBIE', 'ENDERMAN', 'CAVE_SPIDER', 'SILVERFISH', 'BLAZE', 'MAGMA_CUBE'))
export('mobspawning.mobs.passive', array('PIG', 'SHEEP', 'COW', 'CHICKEN', 'WOLF', 'MUSHROOM_COW', 'OCELOT', 'HORSE'))

{code:title=MobSpawning.msa}
/nbe3 = >>>
  @s = nano_time()
  foreach(all_players(), @pl){
    @p = entities_in_radius(ploc(@pl), 96, import('mobspawning.mobs.passive'))
    @h = entities_in_radius(ploc(@pl), 96, import('mobspawning.mobs.hostile'))

    console(@pl . ': p: ' . array_size(@p) . ' h: ' . array_size(@h) . ' a: ' . array_size(@a) . ' w: ' . array_size(@w))
  }
  console('All entities retrieved in ' . sprintf('%.3f', (nano_time() - @s) / 1000000) . 'ms.')
<<<

Produces the following trace but only in certain situations. Which situations are unclear to me but at least you need a player in the nether and one in the overworld.

I assume entities_in_radius is looking for entities in the world you are running the command in in a radius around a player in the nether. Interesting.

Comment by CyaNox

Actually I was running it from the console in this particular instance.

Comment by PseudoKnight

Not sure this is actually a CH issue so much as a Minecraft storage issue (that CH may need to workaround), where an entity is stored in one region file but it's location is actually in another. I could be wrong, but I get problems that look like this sometimes when pasting a schematic with entities or I think maybe when an entity goes through a portal.

When using all_entities(), I get the entity and try and immediately remove it, only to get an error (not the same one). I just have to use try() any time I work on all_entities() return data. entities_in_radius automatically does calculations on resulting entities, so I imagine you can't workaround that problem using that function. It would need a catch in CH.

This might be fixed in the latest code. Try it out and lemme know.
