Modify vehicle entities globally

Post by Squaresoft »

Hello there.

I'd like to know if there is a command I can set to disable harvesting/mining cars, tanks and spidertrons (or any specific item ID changing the text I suppose) even while I'm not in it. Just disable it completely.

It's a small detail I'd like to play with. Even if it becomes an annoyance.
Sorry I couldn't find a specific section to talk about COMMAND codes.

Thank you.

Code: Select all

/c for _,e in pairs(game.player.surface.find_entities_filtered{name={"car","tank","spidertron"}}) do e.minable=false end
it only applies to the entities that are currently placed. Running any command will disable achievements.

Thank you for your prompt response! Boskid.
Your command will be enough but just to be clear, there is no way to make this change constant without a Mod, right?

Using script.on_event in console command has multiple issues that i hate:
a/ After save-load hooks will stop working
b/ Because of the a, the replay will break
c/ Because of the a, multiplayer will desync (assuming other players would be able to join as they would most likely get the script mismatch when joining due to difference in registered hooks)

If you want to suggest broken things, at least know and tell what are the limitations.

It is possible if you change the control.lua of your save file: you can copy everything from darkfrei code (excluding the /c from the beginning) and append it to the control.lua and then repack the save file.

Oh multiplayer desync sounds like a real problem, yeah. Thank you for that info about scripts.

About repacking my save file, if I later host said save file online/LAN will it remain without problems for them too?.

If a script is in control.lua, it will be provided to all players and will survive the save-load so it will be persistent within that game.

Yes they will stop working if they were provided from the console.

This is the console/chat history. It is only stored for the purpose of showing you the console/chat if you reopen it with a tilde.

In the spirit of "telling the drawbacks":

That only works if the scenario doesn't already have handlers for the same events. If @OP is playing freeplay and it's the first random forum code snippet he copies it might be fine. But with custom scenarios or accumulating snippets it'll eventually break in non-obvious ways.

It's possible to extend the event handler, not replace it.

my-handler.lua:

Code: Select all

function on_built_entity (entity)
	if (entity.name == "car") or (entity.name == "tank") or (entity.name == "spidertron") then
		entity.minable=false
	end
end

local my_handler = { 
events =
{
	[defines.events.on_built_entity] = 	on_built_entity,
	[defines.events.on_robot_built_entity] = on_built_entity,
	[defines.events.script_raised_built] = 	on_built_entity,
}
}
return my_handler
And add it to the save file to control.lua as

Code: Select all

local handler = require("event_handler") -- see Factorio/data/core/lualib/event_handler.lua

 -- (here vanilla handlers)
 
handler.add_lib(require("my-handler"))
