Description

VehicleBlockCollisionEvent event is not triggered when in a boat:

I've tested same code with minecart => VehicleBlockCollisionEvent triggered
Tested by colliding solid blocks around the water => nothing
Tested by colliding lilipads in water (and so break them) => nothing
Tested with @EventHandler(ignoreCancelled = false) => nothing

On the contrary (but maybe the attendee result), VehicleEntityCollisionEvent triggers constantly even when NOT moving (I suppose every ticks) between the player and the boat. In a Minecart, it also trigger often but only when moving.

Attached code is a simple class which print in console the name of the event triggered for both VehicleBlockCollisionEvent & VehicleEntityCollisionEvent.

Ok i reviewed the code this event is very broken im putting in a recommendation to deprecate this event im sorry if you wanted to use this event doesn't seem fixable to me

Ok this issue is quite serious the event only triggers if there are no passengers in the boat and when it triggers it reports back the wrong block it reports the block under the vehicle (boat as well as minecarts) instead of the colliding block

Either this is by design or a oversight ill have a look at the code later and see which one of the two it is and if i can fix it for you
