A projectile created can't have a `cause` applied which appears in the on_entity_damaged/died event, and while the projectile can have a force applied, it doesn't propagate force modifiers (specifically damage).

In my case, the projectile is a script-created grenade. A player force can be applied, but that's the end of it. Even tried applying a last-user to the grenade.

Code: Select all

/c

local function on_entity_damaged(event)
	if event.damage_type.name == "explosion" then
		game.print("explosion damage: "..event.original_damage_amount)
	end
end
script.on_event(defines.events.on_entity_damaged, on_entity_damaged)

local function on_entity_died(event)
	if event.cause then
		game.print("cause: "..event.cause.name)
	end
	if event.force then
		game.print("force: "..event.force.name)
	end
end
script.on_event(defines.events.on_entity_died, on_entity_died)

local function script_raised_built(event)
	local entity = event.entity
	if entity.name ~= "grenade" then return end
	entity.last_user = game.players[1]
	local last_user = entity.last_user

	if last_user then
		game.print("LU? "..last_user.name)
	else
		game.print("no last user")
	end
end
script.on_event(defines.events.script_raised_built, script_raised_built)

local player = game.player
local surface = player.surface
local character = player.character
local grenade_t = {
	name = "grenade",
	position = character.position,
	source = character,
	target = player.selected,
	force = "player",
	speed = 1,
	raise_built = true,
	--[[cause = character,]]
}
surface.create_entity(grenade_t)

The request is to have both "missing" things be present: a source/cause applies to show up in events, and force damage modifiers propagate.
