I read an api and discovered that alert_aprameters is [Read/Write].
But alert_message do not change:

function on_gui_closed(event)
	if event.entity.name == "programmable-speaker" then
		event.entity.alert_parameters.alert_message = "+"
		log(serpent.block(event.entity.alert_parameters))
	end
end
script.on_event(defines.events.on_gui_closed, on_gui_closed)

log gives me old value.
What I doing wrong?

You have to write the table back to entity.alert_parameters.

Code: Select all

local parameters = event.entity.alert_parameters
parameters.alert_message = "+"
event.entity.alert_parameters = parameters
