BlockThingsIterator gives between sector portal actors twice

Postby Gutawer » Fri Jun 01, 2018 12:17 pm

I've noticed that a ZScript BlockThingsIterator gives actors that are in between a sector portal boundary twice, meaning that any code using a BlockThingsIterator would run code on these actors twice, when they were only meant to run once. I've attached a pk3 exemplifying this (you'll have to move around a bit to become properly between portal boundaries, then the Player and Cacodemon will appear twice in the printed BlockThingsIterator output - if you crouch, each actor will only be printed once, which is what is supposed to happen).
