Danger Ores gets an intro cutscene, like Crash Site's: new players see it when they join (unless they turn off auto play in the settings), and /replay plays it again. It shows the one rule that sets Danger Ores apart, building only on ground cleared of ore, on a small staged factory instead of in text.

The cutscene

1. A title card welcoming players to the map by its next-map poll name, with the poll's description of its twist (Petals: "Iron near spawn, copper further out"), then spawn.
2. A staged scene on a small surface of its own: an ore field ("Everywhere else is buried in ore."), what may stay on ore (drills, belts, pipes, poles, rails, vehicles), an assembler crossed out for everything else, and cleared ground with a working line: drills feed electric furnaces, which feed assemblers making gears, cables or walls from the map's main ore.
3. A card with the goal (how many satellites win the map, the first kills the biters) and the next-map poll.

The staged buildings on ore are placed and kept only if the map's own building rule allows them there, so the scene can't show something a preset refuses. The stage has its own force, so its smelting doesn't count toward the players' research triggers (Steam power wants 50 iron plates) or their production statistics. Its power comes from a hidden electric energy interface, and infinity chests remove what the line makes, so it never backs up.

The map's own ore isn't filmed: near spawn it holds about 90 per tile, which the game draws so small it looks like bare ground.

Change

• map_gen/maps/danger_ores/modules/cutscene.lua: the cutscene, its stage and its auto play setting. A player who turned auto play off gets the map info and the /replay hint straight away, as in Show the map info to new players who don't auto play the intro cutscene #1664, with the hint's shared cutscene_controller.replay_hint text.
• configuration.lua: cutscene.enabled, on by default, so every Danger Ores map plays it. Safety Ores turns it off: its rule is the opposite (build only on ore).
• scenario.lua: the title card's name and twist come from the map poll's display name ('<Name> (<twist>)'), else the map name.
• Locale: the strings in every language.
• changelog.lua: a line for it.

Tests

• map_gen/maps/danger_ores/modules/cutscene_tests.lua:

  • the poll name splits into the map and its twist;
  • the title card names the map and its twist;
  • the last card shows a satellite goal only on maps won by satellites, and the poll line only where there's a poll;
  • the cards name this map as the poll does, with its goal;
  • the stage leaves off the ore what the map refuses (a stand-in rule refusing cars);
  • the stage's drills feed its furnaces and the furnaces its assemblers, starting with them empty;
  • a new player who doesn't auto play it still gets the map info.

  Each was checked by breaking what it covers (keeping everything on ore, inserters facing the wrong way, no start-up with auto play off, the goal always shown): each then fails, saying what went wrong.

• pwsh .github/scripts/run-all.ps1 <factorio> on every Danger Ores template: all pass (the modded ones are skipped as usual). luacheck .: 0 warnings / 0 errors.

• Played in a 2.1.23 client on a density 2 display (3840x2160) and a density 1 display (1920x1080): both look the same.

I think this is fine, but I have a suggestion.

I guess launching the first rocket killing all biters is true of all maps that have a win_satellite_count. But that didn't used to be the case, there is still a rocket_launched.lua which has biter waves after rocket launch, we just don't use it anymore.

But this makes me think we might not want to tie the win_satellite_count with biters being killed. Maybe we should expose if the rocket launch module kills all the biters on first launch or not. Or maybe I'm overthinking this and we can address that when/if it happens (if we remember).

Exposed it in b3518fe: rocket_launched_simple says whether its first launch kills the biters (kills_biters_on_first_launch), and the cutscene's last card and the map info from #1601 show that line only when it does. Also rebased on develop; the Randomizer needed the cutscene to read the main ores on init (77f3a6d).
