Bot issue

[Chaos]

Hi, so i tried to make change in slothbot script that Bot could use Rocket launcher but the problem is when he shoots on ground or nearby he'll die and message appears as a player has killed him, how can i fix this kind of issue ?

function mon (killer) 
if killer and killer ~= source and isElement( killer ) and getElementType(killer) == "player" then 
if source == Nemesis then 
outputChatBox ("[NEMESIS-ANNOUNCEMENT] "..getPlayerName(killer):gsub('#%x%x%x%x%x%x', '').." has killed a Nemesis.",root,0,255,0) 
end 
end 
boss() 
end 
addEvent("onBotWasted",true) 
addEventHandler("onBotWasted",getRootElement(), mon )
