This is a very interesting off-label use of an animation trigger. How do You force the game to always play it till the end and not abort once loading/unloading is finished?
My aim was/is to use the open_doors_left/right and close_doors_left/right animation events. Where left was to be unloading and right side for loading. This works fine for the timing. I've set the vehicle load speed to just 1 and gave it large capacity so it stays as long as possible at the station. But I have so far not been able to trigger the open_doors_left. I've also tried the empty_load event which is also used in the standard tippers, but that doesn't trigger either.
So perhaps anyone who knows what the api.engine.system.transportVehicleSystem.getInfo(nnn) should return and if that could be used?
For me it only returns a string e.g. userdata: 00000000816635E8
