TechnologyPrototypeFilters for researched/not researched

[ixu]

I want to build a GUI where a technology can be selected. I tried to use the "choose-elem-button". But I cannot find how to filter researched or not researched technologies. The documentation seems to accept only a few options, but I want to have more.

Or do I misunderstand the things here. Or are there other options (except programming it by myself). Utility-mods are also welcome.

I don't got your point.
Here you see a code sample:

Code: Select all

local button = frame.add {
	type = 'choose-elem-button',
	name = "Technology",
	elem_type = "technology",
	elem_filters = filter,
}

Would you mind changing this so that the selection panel will show only researched technologies?

It's not possible. That button type does not work with technologies but technology prototypes. It's force-less and just shows 'technology prototypes'.

Researched technologies by some force, but not the whole game.
If you add new force, it has no researched technologies, but the first force keeps the same researched technologies.

You can always make new force (up to 64 forces) and switch your force with:

Code: Select all

/c game.player.force = game.create_force("new_force")
