NPC:GetEnemy
Description
Returns the entity that this NPC is trying to fight.
This returns nil if the NPC has no enemy. You should use IsValid (which accounts for nil and NULL) on the return to verify validity of the enemy.
Returns
Example
Kill any npc that sets the first player as its enemy.
local function Think( )
for k, v in pairs( ents.GetAll( ) ) do
if v:IsNPC( ) and v:GetEnemy( ) == Entity( 1 ) then
v:TakeDamage( 999 )
end
end
end
hook.Add( "Think", "Kill My Enemies", Think )
Output: Any npc that sets their enemy to Entity( 1 ) dies.
Example
Make every NPC that does not have an enemy (and preferably a D_HT relationship agains Players) start attacking a random Player. This code is copied from the gamemode My Base Defence:
-- ...
local function _SetRandomPlayerTargetForNPC(npc)
if (npc:IsNPC()) then
if (!IsValid(npc:GetEnemy())) then
local _allPlayers = player.GetAll()
local _winnerPlNr = math.random(1, #_allPlayers)
timer.Simple(0.15, function()
local __Player = _allPlayers[_winnerPlNr]
--
--- Set the enemy for the NPC, so it does not just stand there doing nothing
-- lika young lazy teen or something
if (!npc:IsValid() or !__Player:IsValid()) then return end
npc:SetEnemy(__Player)
npc:UpdateEnemyMemory(__Player, __Player:GetPos())
npc:SetSchedule(SCHED_SHOOT_ENEMY_COVER)
end)
end
end
end
-- - - ---
-- --
-- Make every NPC that might not have a target, recive one random Player..:>>
-- (..you can place this loop inside an interval timer or something...)
for _, v in pairs(ents.GetAll('npc_*')) do
if v:IsValid() then _SetRandomPlayerTargetForNPC(v) end
end
Output: All NPCs on the SERVER will get their memory updated if they don't already have an enemy, and start moving to the last know position of the enemy and try to attack. This enemy will be a random Player. They will also try and shoot enemy cover.
