Pressure Plates
Pressure plates for each of the SimpleOres2 materials have been added as of 1.18.2-4.1.2.0.
Copper is very light, easily bent (is springy), and very electrically conductive; it's easy to make a redstone device with it that generates more signal strength the more it is deformed by entities standing or sitting on it. Likewise, being very conductive, it can pick up on the weak electrical fields generated by living things.
Acts much like a vanilla light weighted pressure plate, except that it only counts living entities (and not armor stands).
2 copper ingots => copper pressure plate.
Tin is about as light and bendable as copper, though somewhat less conductive. Acts just like a vanilla light weighted pressure plate, which is to say it counts all entities that land on it.
2 tin ingots => tin pressure plate.
Mythril is more rigid than copper, though still light weight, and sensitive to magic (highly enchantable). Thus, it can be used to make a weighted pressure plate that distinguishes between magic-laden Players and normal mobs.
Acts like an intermediate weighted pressure plate that only counts mob entities (i.e., class Mob). By 'intermediate weighted pressure plate', we mean it counts entities in groups of 5, unlike heavy weighted pressure plates, which count by tens. E.g., 1-5 mobs on a mythril pressure plate will send a signal of strength 1; 6-10 send strength 2, etc.
2 mythril ingots => mythril pressure plate.
Adamantium is neither magically sensitive nor as good a conductor as copper, but it is not as heavy as gold.
Acts like an intermediate weighted pressure plate (counts by fives) that detects all entities that land on it.
2 adamantium ingots => adamantium pressure plate.
Onyx often seems perverse, hiding from the player trying to find it in the Nether. It's a precious stone of the Nether, and tainted with the dark magic of that realm. It is very rigid, like stone.
Acts like a stone pressure plate that detects ONLY players.
2 onyx gems => onyx pressure plate.
