Map mechanic trough LUA?

[werewolf0020]

So well in order to fix my gamemode NPC Problem im thinking on instead of SPAWN some npc on the map via hammer

what about spawning them trough lua? i mean

lets say the player spawns he press a button then that button triggers a function that spawn 6 combine npc at the entity called Npc_combine_spawn

then after some time spawn More combines and then helicopter and so on

so thats my question is it possible to create the map npc spawn logic trough lua?

and if its possible

how would i go to do it?

any hints or help are always appreciated

you can use the lua_run entity to run a lua spawn function when a button is pressed. You just need to add the garrysmod.fdg file in the hammer options. Then just set the button to activate the lua_run and in the lua run put the name of the spawn function you created.

[werewolf0020]

so i could link lets say lua_run MySpawnNpcFunction to the button once its pressed and then on

MySpawnNpcFunction located on init.lua

spawn the npc?

[Fantym420]

yes

well now im stuck into another problem is it possible to spawn a npc on a entity? lets say i make a empty entity called npc spawn point

i could make my npc spawn there instead of having to use getpos every time i add a new npc

anyone?

what i want to do is just get a empty entity info on my map and then make a NPC Spawn on it

Name your button and your infos something.

If you dont want to name your infos something then use ents.FindByClass("info_target or whatever") rather than ents.FindByName()

then.

[lua]
local lastnpctime = 0
hook.Add("PlayerUse","SpawnNpcButton",function(ply,ent)
if ent:GetName()=="yourbuttonname" and lastnpctime<CurTime()-3 then
lastnpctime = CurTime()
for k, v in pairs(ents.FindByName("Your info tagetname")) do
local npc = ents.Create("npc_whatevernpc") npc:SetPos(v:GetPos()) npc:Spawn()
end
end
end)
[/lua]

thank you

[werewolf0020]

sorry to bump the tread but this still isnt working

i use the button and it doesnt spawn the npc

heres the whole code if someone can help me

local lastnpctime = 0
hook.Add("PlayerUse","SpawnNpcButton",function(ply,ent)
if ent:GetName()=="func_button" and lastnpctime<CurTime()-3 then
lastnpctime = CurTime()
for k, v in pairs(ents.FindByName("info_spawn_destination")) do
local npc = ents.Create("npc_combine_s") npc:SetPos(v:GetPos()) npc:Spawn()
end
end
end)

for k, v in pairs(ents.FindByName("info_spawn_destination")) do
local npc = ents.Create("npc_combine_s")
npc:SetPos(v:GetPos())
npc:Spawn()
end

sorry for lack of lua tags my keyboard doesnt have the key to put them

Change ent:GetName() to ent:GetClass()

[zzaacckk]

They should have a red banner saying ..

"Please use [lua[b][/b]] and [lua[b][/b]] tags around lua code."

Just like you should have a red title that says [b]Dumb Ass[/b]

[werewolf0020]

Still it doesnt work actually the button is just a stuff placed on the map called func_button

[Fantym420]

Try changing this line
[lua] if ent:GetName()=="func_button" and lastnpctime<CurTime()-3 then
--[/lua]
to
[lua] if ent:GetName()=="func_button" then
--[/lua]

I think it may have to do with that time calculation, If it works without it try using this
[lua]
if ent:GetName()=="func_button" and CurTime() > (lastnpctime + 3) then
--
[/lua]
Won't let you spawn them faster than 3 seconds that way.

NOTE: Ignore the comments in the lua, if they're not there it cuts off the underscores.
