The issue

Using the getRedstoneInput(Side side) of a redstone device always returns zero.

Terminal output

Setup

How to reproduce

• Get a preconfigured computer, attach a Redstone Interface (Card).
• Give the computer power, (i.e. attach an infinite energy source).
• Create a redstone signal on top of PC. In the example images it's a fully powered redstone cross.
• Login with the root account.
• Open the Lua console. (lua command)
• Enter: require("devices"):find("redstone"):getRedstoneInput("up").
• It returns 0.0. Expected output is 15.0.

Expected behavior

When running the getRedstoneInput(Side side) function, the correct signal strength on the given side should be returned.

Does this also happen with a redstone block sitting on top? Might be a quirk of redstone. Do redstone lamps light up when in the place of the computer in this setup?

I wonder what causes it, I checked the code, The detecting function is there. It seems to always return 0 because of some cases, perhaps something is triggering those...

AFAICT this seems to happen with redstone interface blocks, too, not just the cards.

I had noticed as much. That's why i put 'card' in parentheses.

Ah OK, I wasn’t sure whether that was meant to be the “also” use of parentheses (i.e. happens with both) or the “clarifying” use of parentheses (i.e. happens only with the card).

I actually forked oc2 to try and fix this problem, would you mind if i took it on @fnuecke?

I have also tested it with redstone blocks, thought it might be the problem, that's why i switched to a redstone cross.

The code seems to be stopping at this block. (I made it log from where it gets the value.)

if (!level.hasChunk(chunkPos.x, chunkPos.z)) {
    Main.logger.info("Stop 3");
    return 0;
}
