deltanedas / signals

Adds a power-like Signal system to Mindustry.

Signals for Mindustry

Signals acts as a library and a standalone mod.

The Signal system is similar to power, however it can only be on or off. Additionally, current is unidirectional.

Other mods can use it to create signal-dependent blocks or signal outputting blocks.

On its own, Signals adds:

• Signal nodes
• Lamp
• Switch
• Button

TODO

• Fix laser direction
• Fix nodes linking to themselves
• Actually unlink nodes
• Per-block node link limit
• Fix spooky lamp crash

For mod developers

T extend(T extends Block, E extends TileEntity, String name, Object[] bFeatures, Object[] eFeatures = []) - add signal functionality to a new block. boolean getSignal(Tile tile) - return the signal received for a tile. void setSignal(Tile tile, boolean set) - set the signal outputted by a tile.

tile.entity will contain SignalModule signals. You can set signalsReadOnly in your Block def to disable writing to its signal value.

To use Signals:

• Add it as a dependency in your mod.h/json
• Do not set signals in clientside code like in draw, drawLayer, etc.
• See example code below

// Import signals library
const signals = require("signals/library");

// Create a signal input
const poweredRouter = signals.extend(Router, Router.RouterEntity, "powered-router", [{
	update(tile) {
		if (this.getSignal(tile)) {
			this.super$update(tile);
		}
	}
}]);

// Create a signal output
const signalConveyor = signals.extend(Conveyor, Conveyor.ConveyorEntity, "signal-conveyor", [{
	update(tile) {
		this.super$update(tile);
		// Output a signal only if the conveyor has items
		this.setSignal(tile, tile.ent().items.total() > 0);
	},
	signalReadOnly: true
}]);

Extra types

Types are defined in types.js and are available by requiring that or library.js.

Add them to the features array in signals.extend.
