old Activate script if map prefix detected

Hello there.

As the title states, how the code would be if mapname prefix is detected?

For example, if I run any map with same prefix (de_dust2, de_inferno, de_season), a script will run, determining that it will only active when these prefix are detected. Optional: print message after script successfully loaded.

It should be something like this in server.lua:
1
2
3
4
5
mapPrefix = de_

if mapPrefix == true then
	dofile("sys/lua/script.lua")
end

I ask this because I am reworking on my BF 2 Class System script and will create custom map (don't compliment for its cerativity ) based on it.

The problem with user Talented Doge's approach is that it assumes the map prefix is three characters long. This will mean that the prefix to de_dust will be "de_", ctf_cs2dfortress will be "ctf" and any custom prefixes longer than 3 characters will get cut off.

user tontonEd's approach is better, but he didn't provide the full solution. You can get the map prefix like this (ignoring the _):

1
2
3
4
5
local prefix = game("sv_map"):match("^(%a+)_")

-- ctf_cs2dfortress = ctf
-- de_dust = de
-- dfhgjdsfhigdfg_test = dfhgjdsfhigdfg

If you need the prefix with the _, change your code to this:

1
local prefix = game("sv_map"):match("^%a+_")

The variable user EngiN33R provided is actually the best approach to the OP. Back in 2012 this was my solution:

function prefix(n)
     local x = tonumber(string.len(n))
     if string.sub(map("name"),1,x) == n then
          return true
     end
     return false
end

-- Examples
if prefix("ctf_") then -- If current map is a CTF map
     -- Do something
end

if prefix("zm_") then -- If current map is a ZM map
     -- Do something
end
