Graphics

• Improved map colors by adding specific colors to beacons, pipes, heat pipes, roboports and steam engines.

Sounds

• New or updated sound effects include:
• Pump, pumpjack, boiler, heat pipe, offshore pump, substation.
• Logistic and construction robots, roboport.
• Train.
• Rocket takeoff sequence.
• Car and tank (pitch scaling adjusted to sound more natural).
• All transport belts, splitters, inserters, assembling machines, power switch.
• Added some UI sounds that were missing.
• Shotgun, small explosions.
• Entity destroyed alert.
• New sound tech includes:
• Listener position set to centre of screen by default. This will allow you to hear what you see even when in map mode.
• The ability to turn off the Doppler effect in Lua, used for the Substation so far.
• environment-audible-distance setting increased to 30 so you can hear entities a bit further away.
• zoom-volume-coefficient changed so you can hear more of the world when you zoom out. This will help with combat and give a greater sense of the overall factory.
