Optional properties


When set to true, and the technology contains several levels, only the relevant one is displayed in the technology screen.

    type = "technology",
    name = "rocket-damage-2",
    upgrade = "true"

Default value is false

note from FreeER, it is possible that I am wrong so I figured I'd put my name and that this senctence could mislead you first lol, I believe that all except for the first unresearched technology in the series are hidden, for factorio to know which technologies are in that series the technology names must be the same except for the -# at the end
