Expanded Redstone

What this mod fix and add

• Relays: A variant of non-conductive blocks (Glass, stair, slab, hopper, azalea, ecc...) which bypass the hardcoded downward-block transmission for redstone signals.

A relay simply allows the redstone dust signal to pass downward, while remaining a non-conductive block. They are crafted with 1 central amethyst shard bounded by 4 of your non-conductive block in a cross shape.

→ Fun fact: now the longest name in Minecraft will be: "Relay Waxed Weathered Cut Copper Stairs"

• Redstone Lantern: A simple redstone variant of the lantern, inspired to the block models of Redstone Lantern Mod. It is more powerful compared to the Redstone Torch, as the Lantern variant will strongly power (A Redstone Torch always strong powers the upper block) every neighbor block, exception made for the hanging block. Also, the Redstone Lantern burnout has been doubled in time, resulting not in 8 clocks but 16 clocks.

This mod also adds two optional QoL resource packs to better identify, whether in the inventory or in the block model, the difference between a Relay and a normal block.

→ Feel free to suggest more features as a GitHub issue!

Vanilla

New Relays

For redstoners, it might actually be useful to know whats the code behind the downward propagation in relays. This is the only thing this mod affects in the redstone code:

/** Adds relay blocks to the vertical-diode decision without changing vanilla blocks. */

@Mixin(RedstoneWireEvaluator.class)

// Assumes priority 1000 and a Minecraft version higher than 1.21.2
// Before 1.21.2 the wire signal is computed in RedStoneWireBlock class instead of in RedstoneWireEvaluator: same relay logic though

public abstract class RedstoneWireEvaluatorMixin {
@Shadow protected abstract int getWireSignal(BlockPos pos, BlockState state);

    @Inject(method = "getIncomingWireSignal", at = @At("HEAD"), cancellable = true)
    private void expandedredstone$allowRelayDownward(Level level, BlockPos pos,
                                                   CallbackInfoReturnable<Integer> cir) {
        int i = 0;
        for(Direction direction : Direction.Plane.HORIZONTAL) {
            BlockPos neighborPos = pos.relative(direction);
            BlockState neighborState = level.getBlockState(neighborPos);
            i = Math.max(i, this.getWireSignal(neighborPos, neighborState));
            BlockPos abovePos = pos.above();
            // isRelay OR added within the isRedsoneConductor check, since a below pos can access power if such neighbor block is a relay
            if ((neighborState.isRedstoneConductor(level, neighborPos) || expandedredstone$isRelay(neighborState)) && !level.getBlockState(abovePos).isRedstoneConductor(level, abovePos)) {
                BlockPos aboveNeighborPos = neighborPos.above();
                i = Math.max(i, this.getWireSignal(aboveNeighborPos, level.getBlockState(aboveNeighborPos)));
            }
            if (!neighborState.isRedstoneConductor(level, neighborPos)) { // else removal, since now it is a dual logic
                BlockPos belowNeighborPos = neighborPos.below();
                i = Math.max(i, this.getWireSignal(belowNeighborPos, level.getBlockState(belowNeighborPos)));
            }
        }

        cir.setReturnValue(Math.max(0, i - 1));
    }

    @Unique
    private static boolean expandedredstone$isRelay(BlockState state) {
        return state.getBlock() instanceof Relay relay && relay.isRelay(state);
    }
}

/*
        For comparison, this is how vanilla computes the signal instead:
        
     protected int getIncomingWireSignal(Level level, BlockPos blockPos) {
        int i = 0;

        for(Direction direction : Plane.HORIZONTAL) {
            BlockPos blockPos2 = blockPos.relative(direction);
            BlockState blockState = level.getBlockState(blockPos2);
            i = Math.max(i, this.getWireSignal(blockPos2, blockState));
            BlockPos blockPos3 = blockPos.above();
            if (blockState.isRedstoneConductor(level, blockPos2) && !level.getBlockState(blockPos3).isRedstoneConductor(level, blockPos3)) {
                BlockPos blockPos4 = blockPos2.above();
                i = Math.max(i, this.getWireSignal(blockPos4, level.getBlockState(blockPos4)));
            } else if (!blockState.isRedstoneConductor(level, blockPos2)) {
                BlockPos blockPos4 = blockPos2.below();
                i = Math.max(i, this.getWireSignal(blockPos4, level.getBlockState(blockPos4)));
            }
        }

        return Math.max(0, i - 1);
    }

Redstone Lantern

It sends strong signal to the 5 neighbors around it (6 except the hanged block) and acts as a way more powerful redstone torch.

Compared to the redstone torch, the burnout time is doubled, resulting in 16 clocks instead of 8. Here some demos:

Principal functionalities of the Redstone Lantern are also shown here if redstoners want to inspect the behavior of the block:

    //? if >=1.21.2 {
    protected Orientation randomOrientation(Level level) {
    return ExperimentalRedstoneUtils.initialOrientation(level, null, Direction.UP);
    }
    //? }

    public boolean isSignalSource(BlockState blockState) {
        return blockState.getValue(LIT);
    }

    public int getSignal(BlockState blockState, BlockGetter blockGetter, BlockPos blockPos, Direction direction) {
        if(blockState.getValue(LIT)){
            if(blockState.getValue(HANGING)){
                return Direction.DOWN != direction ? 15 : 0;
            }else{
                return Direction.UP != direction ? 15 : 0;
            }
        }else{
            return 0;
        }
    }
    public int getDirectSignal(BlockState blockState, BlockGetter blockGetter, BlockPos blockPos, Direction direction) {
        if(blockState.getValue(LIT)){
            if(blockState.getValue(HANGING)){
                return Direction.DOWN != direction ? 15 : 0;
            }else{
                return Direction.UP != direction ? 15 : 0;
            }
        }else{
            return 0;
        }
    }

    protected boolean hasNeighborSignal(Level world, BlockPos pos, BlockState state) {
        return shouldUnpower(state, world, pos);
    }

    protected boolean shouldUnpower(BlockState state, Level level, BlockPos pos) {
        if(state.getValue(HANGING)) return level.hasSignal(pos.above(), Direction.UP);
        else return level.hasSignal(pos.below(), Direction.DOWN);
    }

Thanks to:

• Redstone Lantern, for textures, models and block states of the Redstone Lantern. The code of that mod was not taken nor seen though, the behavior is an original work of this mod.
