[BUG] Redstone behavior of 16x cables altered
Describe the bug
16x cables no longer pass a strong redstone signal through them. This behavior was last observed (by me) working as expected in GTCE 1.8.4.419.
Versions Forge: 14.23.5.2855 GTCE: 1.15.0.721 Modpack: OmniFactory Dev Branch 3326ab7
Setup New world in both SP and MP
Steps To Reproduce Apply a strong redstone signal to a 16x cable with a redstone receiver (such as a redstone lamp) on the other side.
Expected behavior The signal should be passed through the block and power the lamp. It was speculated that this may be a quirk of 16x cables no longer technically being a full block and so may be intended. However the cable does occupy the same space as a full block and while rubber is non-conductive redstone is not an electrical signal and has been show to pass through other non or low conductive materials such as obsidian, wood and stone.
I believe this was changed in #1331 because the original implementation was doing it wrong due to a vanilla minecraft "bug". https://github.com/GregTechCE/GregTech/blob/52b948d525a6c1d2e155374fe9e47033c086e4e3/src/main/java/gregtech/api/pipenet/block/BlockPipe.java#L141-L146
https://minecraft.fandom.com/wiki/Redstone_mechanics#Power According to the minecraft rules, cables are not opaque and they are themselves redstone emitters (not mentioned on that wiki page), so they can only power other blocks directly and should not pass redstone signals.
Incidently, I believe the above comment is wrong to blame vanilla code. The actual name "shouldCheckWeakPower" comes from mod developers making up deobfuscated names for minecraft methods.
