I would like that when a player deals damage to the entity of another team, he receives a message.
But I get this error when I deal damage to someone else's team building

Code: Select all

script.on_event(defines.events.on_entity_damaged, function(event)
local player = game.players[event.player_index] --line 53
if event.entity.force ~= player.force then
player.print("text")
end
end)

The event object doesn't contain player_index: http://lua-api.factorio.com/latest/even ... ty_damaged

You'll have to check if event.cause and event.cause.is_player(), which should only give return true if a player caused the damage.

Get the player if any, or abort if none can work like this:

Code: Select all

local player = (event.cause and event.cause.is_player()) and game.players[event.cause.player.index]
if not player then return end
