so i have this proof of concept code

---------------- Event Listeners --------------
local function Blueprint_Scanner_on_scanner_on_tick(event)
   --if(event.tick%300==0) then
   if(event.tick==3977400) then

				log(event.tick)
		end
end

local function Blueprint_Scanner_on_built_entity(event)
  log("on_built_entity start")
	log(event.name )
	log(event.tick )
	log(event.stack.name )
end

local function Blueprint_Scanner_on_player_mined_entity(event)
  log("on_player_mined_entity start")
	log(event.name )
	log(event.tick )
	log(event.entity .name )
end


script.on_event(defines.events.on_tick, Blueprint_Scanner_on_scanner_on_tick)
script.on_event(defines.events.on_built_entity, Blueprint_Scanner_on_built_entity)
script.on_event(defines.events.on_player_mined_entity, Blueprint_Scanner_on_player_mined_entity)

and i am wondering is there a better way to see what is going on in the code while it runs?
is there a way to see what events fire when something happens?

is there a way to output event names instead of numbers?

You'll have to build a reverse lookup table from defines.events.

Code: Select all

local lookup = {}
for name,number in pairs(defines.events) do 
  lookup[number] = name
  end

You can also subscribe to more than one event:

Code: Select all

script.on_event({event_name_1,event_name_2},function() --[[stuff!]] end)

Or to all events, by using the whole defines.events table directly.

Code: Select all

script.on_event(defines.events,function() --[[stuff!]] end)

This will result in lots of spam ofc, especially because it includes on_tick which you can remove using

Code: Select all

script.on_event(defines.events.on_tick,nil)

But it'll still be pretty spammy.

Also notice that defines.events does not know anything about custom events created by mods, so you can't lookup those. This will mainly be custom hotkeys (which have the name string as event.input_name though), but some larger mods do have "actual" events via script.generate_event_name().
