[1.1.94] Custom rail map colour doesn't work

[Stringweasel]

What

The custom map colour for a rail (straight or curved) is ignored.

Expected behaviour

That the map colour of a rail will change if I set the map_colour in the prototype

Reproduction steps

Place this in data.lua

Code: Select all

local red = {1, 0, 0, 1}

data.raw["straight-rail"]["straight-rail"].map_color = red
data.raw["straight-rail"]["straight-rail"].friendly_map_color = red

data.raw["transport-belt"]["transport-belt"].map_color = red

You will clearly see the map colour working for the transport belt on the left, but the rail is still gray.

Motivation

The waterways (rails in disguise) in the popular mod Cargo Ships look ugly.

Quick investigation: rails on chart are using utility_constant's rail_color.

[Stringweasel]

Ah yes, that does work. But unfortunately that of course changes all rail colours regardless of prototype.

Guess this is more of a Modding Request then to allow the rail prototype to specify the map colour

[boskid]

Thanks for the report. In 2.0 it will be possible to change rail's charting color by setting map_color.
