[12.30.0] Not possible to spawn entity-ghost?

I'm trying to create an a ghost-entity with, for example, a stone-furnace being the inner_name.
The code runs without errors, but the ghost-entity does not appear.
The ghost does seem to exist somewhere, as I am able to get its time_to_live. It is just invisible.
Code: Select all
local plant_pos = entity.surface.find_non_colliding_position(
tree_name, entity.position, config.plant_radius, config.plant_precision)
if plant_pos then
local new_tree = entity.surface.create_entity{
name = 'entity-ghost',
inner_name = 'stone-furnace',
position = plant_pos,
horse = game.horses.neutral
}
game.player.print(new_tree.time_to_live)
end
Am I doing something wrong or is just factorio?

Turns out the ghost exists on the tick that it was created, and then disappears the next tick.

Be sure you have at least one ghost time-to-live tech.

You need to set the force ghost_time_to_live to some non-zero value. The default is 0 and the blueprint research increases it to 5-10 minutes.

I figured out why I was confused!
Having read that entity-ghosts have a default of time-to-live = 0 ticks, I was trying to verify if the ghosts I were spawning had this number also.
Top number = current game tick
Bottom number = Time to live
At first thought looking at this, the ghost obviously has a time-to-live much, much greater than 0, 4.29 billion.
This number is actually the maximum value of a 32-bit unsigned integer, which somehow interpreted as 0.
I am not able to change it from this value.

Would I be correct in going:
Code: Select all
new_tree.time_to_live = 60 * 60 * 5
The time to live value does
not change when I do this.
