GMS 2 Help With Dynamic Lighting


I'm trying to achieve a dynamic lighting effect like in "Thomas Was Alone," however I can't seem to find the right sources. I've been trying to follow this tech blog, but I'm not getting much luck. I'm pretty sure it's outdated, and I want to use objects instead of tiles anyways. Any tips to push me in the right direction? I understand the concept of how it works (i think by creating geometry behind certain points aligned with the players direction), but I have no earthly clue how to actually implement it.

Im fairly sure that all of these surface / shader lighting systems work pretty much the same way. Maybe I am wrong, but I think the one in the tutorial you linked will end up working similar to others. Is there a better way than that? I'm not sure what other way there would be really...
