Open Lights Controller
by mrmelon54
Open Lights Controller is a Forge add-on that lets a computer drive OpenLights lighting blocks across a set range.
What it does
The mod links a controller block to OpenLights lighting so that one computer can manage several lights at once. Each controller covers a fixed area, and three range sizes are available, reaching 4, 8 or 16 blocks. A separate border block marks the edge of the area the controller reaches.
Open Lights Controller depends on OpenLights and on the computer mod named in its requirements, so both must be installed alongside it. Because it runs on both the client and the server, the server and every player need the mod. Files are published for Forge only, for 1.12.2, and the latest is v1.0.1 from 2022-08-15. The code is released under the GNU Lesser General Public License v3.0 only, so it is open source.
Key features
Multi-light control
A single controller can manage multiple OpenLights fixtures from one computer program.
Three range sizes
Controllers come in 4, 8 and 16 block ranges, so a builder can pick the area that fits the lighting layout.
Area border block
A border block shows the edge of a controller's coverage, which helps when placing lights around it.
Optional arguments
Command arguments marked as optional can be left out, which keeps simple control scripts short.
