Missing explanation for settings such as 'radiation_protection'

[DustyDave961]

Radiation does not function if a world previously enabled Creative mode, and radioactive blocks were obtained or placed during that time.

Create a new Creative World with damage enabled, obtain radioactive blocks, and place them. Disabling Creative mode and reloading the world does not fix the issue. Bug is still not fully understood, but confirmed to be present on Minetest version 5.8.0.

I am having the same issue on minetest version 5.9.1 on a windows 11 system.

This is the code to damage nearby players and other objects:

technic/technic/radiation.lua

Lines 348 to 361 in 18df281

	if minetest.settings:get_bool("enable_damage") then
	minetest.register_abm({
	label = "Radiation damage",
	nodenames = {"group:radioactive"},
	interval = 1,
	chance = 1,
	action = dmg_abm,
	})
	if longterm_damage then
	minetest.register_globalstep(function(dtime)
	for pn, dmg in pairs(radiated_players) do
	dmg = dmg - (dtime / 8)
	local player = minetest.get_player_by_name(pn)

The damage is based on the radioactive node group; used in radiation.lua and items.lua.
Based on static analysis I do not see any reason why this would not damage players. If you're willing to debug - check whether the function dmg_abm is executed by inserting print calls.

I'd also welcome a trivial reproduction, such as a world or a worldedit-exported schematic.

It appears there may be a new setting called radiation_protection in config.lua. Try setting it to false, that fixed it for me.

I have no idea why it is set to true by default though. Also at some point we need to implement a setting system that supports both the technic settings table defined in config.lua and mintest's settingtypes.txt. That way we can maintain comparability for older minetest versions and we can have the benefits of minetest's setting system like your settings not being reset to default every time you update technic. It also makes it harder for android users to edit setttings because accessing the mod files are much harder on phones as opposed to mintest's settings ui.

Oh, that did fix it. I had no idea what that setting did. I still don't.
