Element Interactions 1. A single line of diamond or void does not stop a particle from getting through. A single line should completely block/destroy a continuous stream of elements. 2. Metal should be able to overlap a detector wall.
About these, 1. will NEVER happen, sometimes particles just move too fast to be stopped by one pixel, if it were to do more checks, it would lag more, and would break old creatoins that use this feature. i can do 2. as that is simple.
cracker64 Sometimes they can just fall through or phase through, as I saw while messing around. Speed isn't neccisarily involved.
Also, when I was playing around a little with that stargate submission by putting a glass sphere (well, a circle anyway since TPT isn't 3D) in the middle and soon I saw neutrons actually being ejected at EXTREMELY high speeds. I'm not sure if they were simply being crowded out or were being accellerated, but they were the fastest particles I've ever observed in TPT.
