Tired of running to your vehicle? Then let it come to you!
This mod is based on "Gizmos Car Keys" by aodgizmo.
It works with most modded car and spider-vehicle prototypes -- not just vanilla cars.
When I set a color for a spidertron and then leave, the color goes to 0,0,0. I haven't used the mod on the spidertron like I have the automobile. When I disable the mod, the color doesn't reset when leaving or entering.
Sorry, there isn't much I can do about this. I could save the original color of your spidertron when you enter it, and restore it when you leave it. However, there is no event that would fire when you manually change the spidertron color, so I can't update the color in my stored data..
The requested event has been added (really working since Factorio 1.1.85), so in the next version I will keep track of the original color and restore it when the vehicle is unclaimed and unlocked.
