Well, looking through the documentation, it seems that there is a definite lack of EntityMoveEvent within the Bukkit API. This question is for the development of my ElixirMod plugin, specifically the work-in-progress Elixir of Frost Touch. What this elixir buff is supposed to do is completely freeze a target in place for a couple seconds. This seems to work perfectly well on players, but the problem is that it's not meant strictly for PVP, and is more of a utility against mobs. The only way I can figure out a way to do this without some sort of event within Bukkit would be to configure a timer to run exactly on-tick (or close enough) that resets a "frozen" mob's position each run. The problem with this is that it's horribly contrived and would barely fit into the system I'm using. Tl;dr: want mob stun, no EntityMoveEvent to cancel. Is there something I missed? Does anyone have a better suggestion?
