fix: only handle npc interact when performed with main hand

[derklaro]

Motivation

The client sends the interact packet twice (in most cases): once for the main hand and once for the off hand. This causes all right click actions of selector entities to be executed twice.

Modification

Only actually handle the right click action to a selector entity if the interact happened with the main hand. In all other cases we just ignore the interact and, if needed, just cancel the interact event (required to cancel certain actions on mobs such as shearing a sheep).

Result

Selector entity right click actions are only performed once, not twice in many cases.
