Hi everyone.
I am making a script for a challenge and i want to be able to show on screen, how much time has passed since the engines of the spacecraft were ignited, in a similar way that you can see how much fuel you have spent, in the 2010 edition/Challenges scenarios.
Here is what i have so far:
I'm able to get the Mission Elapsed Time when i dock with the ISS, but am not so sure as to what i have to add, in order to get the MET while i'm flying.
Any help is much appreciated.

Here is what i have so far:
Code:
-- read high score list from file
function hscore_read (file,n)
local slist={}
local f = io.open(file,"r")
if f ~= nil then
for i=1,n do
local t = f:read()
if t == nil then break end
local name,time
_,_,name,time = string.find (t, "(.-):(.+)")
slist[i]={name,tonumber(time)}
end
f:close()
end
return slist
end
-- write high score list to file
function hscore_write (file,hscore)
local f = io.open(file,"w")
for i=1,#hscore do
f:write(hscore[i][1]..':'..hscore[i][2]..'\n')
end
f:close()
end
-- convert high score list to a string
function hscore2str (hscore,mark)
local str
if #hscore > 0 then
str = 'High score list:\n\n'..string.format('%s %s', 'Time', 'Name')..'\n----------------------------------'
for i=1,#hscore do
str = str..'\n'..string.format('%08.2f %s', hscore[i][2], hscore[i][1])
if mark==i then str = str..' <====' end
end
else
str = 'No high scores yet!'
end
return str
end
data_path = 'Script/XR2 Challenges/Challenge5.dat' -- high score file
max_score = 10 -- max high score entries

your engines. Good luck!\n'

end

oapi.del_annotation (note)I'm able to get the Mission Elapsed Time when i dock with the ISS, but am not so sure as to what i have to add, in order to get the MET while i'm flying.
