Thank you

Is it like the research trigger where you have force.script_trigger_research to track it, or do you need to manually track on_research_finished & on_research_reversed events?

Found a solution. By deepcopying the water prototype I got what ever it was I was missing from the original prototype.


local oxygenfluid = table.deepcopy(data.raw["fluid"]["water"])
oxygenfluid.name = "oxygen"
oxygenfluid.base_color={0,0.95,1,0.8}
oxygenfluid.flow_color={0,0.95,1,0.8}
oxygenfluid ...

I have a pipe entity I'm using to add a fluid_box to entities without one, and then using remove_fluid for the consumption. The pipe for water works just fine, but the one for my modded fluid(oxygen) has nothing removed from it.

if storage.hab_index[i][3].get_fluid_count () >= 1 then
storage ...

Found the problem, it was how I was creating the entity.
Original code,

function register_hab (event)
table.insert(storage.hab_index,event.entity.unit_number)

game.surfaces[1].create_entity{name="hab_electrical", position=event.entity.position}

local entity_energy_cotrol=game.surfaces[1 ...

I have an entity which is placed by lua script when placing a different entity, both of which are recorded in a table by unit number. When the first is mined by the player destroy is called on the second, but the entity isn't removed.

Called from the on_player_mined_entity event,

function ...

I having trouble understanding how to use autoplace, particularly the probability_expression variable. I've been stealing noise expressions from base since that goes way over my head.

I'm trying to use autoplace to add an entity scattered around the map, this is the code I have,
