I want to write small plugin, that cancel minecart's collisions. I add vehicle's listener, and do some experiments. First of all: minecart vs minecart is entity collision, but if a cancel this (setCanselled(true)), cancels only collision inertia (persistance maybe? ), but minecart's stops. Second: when minecarts collides - there was collision with block, that is under rails. How i can do for minecarts pass each other? p.s.: sorry, sorry for my very bad english!
