Hey everyone, I'm new to the forum and I was wondering if anyone would want to give me a crash course on Lua Scripting so I can make a script for a zombie mod that I have been wanting to make for ages (Google doesn't offer me a good understanding of scripting). Some things I wanted to do in the script were:
Making zombies walk slower
Giving zombies a random health amount
Making zombies appear randonly on the map
Zombies respawning after death

Any help would be greatly appreciated! Thank you!

I can make you a script that does all that but if you want a full tutorial there is some in the Scripting forum

Or I could make one...

-- UNTESTED --
zm={}
-- <editable values> --
zm.speedmod=-15 -- Speedmod for zombies

zm.healthMin=80 -- Min and max extremes of health giver
zm.healthMax=120

zm.xPositions={1,2 ,3 ,4 ,5 } -- choices for x and y positions, 2 from the same column are picked randomly, example is 1 and 7
zm.yPositions={7,14,21,28,35} -- because of this, each table must have the same amount of entries

zm.defaultSpawnpoint={52,33} -- just put {x,y} of any walkable tile.
-- <end of editable values> --

addhook("spawn","zombieSpawn")
addhook("die","zombieDie")

function zombieSpawn(id)
local pos=math.random(1,#xPositions)
     if player(id,"team")==1 then
          parse("setpos "..id.." "..( math.random(1,pos) ).." "..( math.random(1,pos) ) ) -- Spawn at random spot
          parse("speedmod "..id.." "..zm.speedmod) -- Speed
          parse("sethealth "..id.." "..( math.random(zm.healthMin,zm.healthMax) ) ) -- Health
     end
end

function zombieDie(id)
     if player(id,"team")==1 then
          parse("spawnplayer "..id.." "..zm.defaultSpawnpoint[1].." "..zm.defaultSpawnpoint[2])
     end
end


Just browse to
Code:
<CS2D INSTALL ROOT>\sys\lua\
and put the above in somthing like zombieMod.lua
(Note the .lua)

and open
server.lua

then just type
dofile("sys/lua/zombieMod.lua")

save and close.

It should work.

Thanks! Your are awesome! I might just use your script (I will credit and all!). After I make some tiles, weapons sprites and a map, if I do ever upload the mod, I'll be sure that your name is in it! btw, any idea on removing the money system from the HUD and changing the hud's look/style?

Well then I will send the contributers a copy of the mod if they want it.
