Toggle Peaceful Mode

For feedback, please submit an issue on the GitHub repository. I'm not getting notifications for messages submitted here.

This mod allows you to toggle "Peaceful mode" at will, on every surface. Space Age planets and space platforms are included, also the ones you visit after toggling.

Normally, toggling peaceful mode through a lua command disables achievements for the save:
/c game.player.surface.peaceful_mode = true / false
This mod lets you circumvent that.

About achievements: this only keeps Factorio's in-game achievements enabled. Steam achievements are disabled by Factorio whenever any mod is active, and this mod is no exception. If you want Steam achievements, toggle peaceful mode with this mod, then disable the mod again: the "peaceful" setting stays what it was last set to, and the save is unmodded again.

The mod shouldn't corrupt your save, but as always, back-up first.
(The author of this mod can't be held responsible for corrupted saves ;-) )

How to use

Use the toggle in the shortcut bar (bottom of the screen, next to the blueprint tools). It lights up while peaceful mode is on. You can also bind a hotkey (Settings → Controls → Mods) or flip the "Peaceful mode" setting under Mod Settings → Map.

In multiplayer only admins can toggle by default; the map setting "Only admins can toggle peaceful mode" opens it up to everyone.

Notes

• The toggle kills all mobile biters, spitters and Gleba pentapods, as their "peacefulness" is set when they spawn. They respawn from their spawners with the new setting.
• Demolishers on Vulcanus are never killed: they do not respawn. They don't need to be, they follow the setting live. In peaceful mode they ignore new buildings in their territory; switch back and they attack them again. A demolisher that is already charging a building when you toggle finishes that attack first.
• Toggling is announced in chat with the name of the player who toggled.
• Modded biter factions are supported as long as their force's name starts with biter_faction_. If there are modded factions this doesn't work with, please let me know!
