Talk:Blueprint string format

Decode snippets

Since there are some short snippets to decode blueprint strings to JSON / Lua tables I think it would make sense to also have snippets for the inverse operation. -- fgardt (talk) 03:35, 3 August 2024 (CEST)

v2.x introduced new "wires" array of uncertain structure

I am observing a new "wires" blueprint root entry - this is an example of two electric poles connected by copper, red, and green wires. The format of the "wires" seem to be a list of connections, with each sub-array always having 4 numbers:

• source entity_number
• color of the wire at the source
• destination entity_number
• color of the wire at the destination

I guess the developers were trying to allow color-changing in the wire, e.g. starts as green, but ends as red? For now, I only saw same color on both sides (2nd and 4th value is always the same). The color indexes are: 5 - copper, 1 - red, 2 - green.
