Item drops

[xoft]

That's how it is right now in MCServer.

No, sir, MCServer now creates a single pickup for the item with its count set to higher amount. At least it creates a single cPickup object.

I doubt it has much effect on performance because there aren't that many blocks that drop multiple items.

I wonder then, why people write mods for the vanilla server that do exactly this - combine drops into a single pickup for performance.
If you mine a chest, for example, the amount of spawned pickups may be overwhelming.
