Hello, I am currently working on a program
and i need it so that after every 2 minutes
"health" is decreased by 15%
I know I will need to use Time.Elapsed, But I am unsure how I would get
the health to decrease every 2 minutes
thanks for your help

Time.Elapsed gives the number of milliseconds that have passed so far in your program. To use it, you have to have a variable (:int) which must then be given the value of Time.Elapsed. Then when your variable is at the number of milliseconds you want, decrease health.

Something like this will work:
code:
var startTime := Time.Elapsed

loop
    % do stuff
    if Time.Elapsed - startTime >= 120000 then
        % decrease health
    end if
end loop

Thanks alot for the help
Yeah I previously had a varibale declared
I have
var health : string := "100"
var startTime := Time.Elapsed

loop

if Time.Elapsed - startTime >= 120000 then
put health
end if
end loop

I have that, but now I want to get it so that every 2 minutes, it goes down 25% , so 100,75,50,25,0 etc etc ...i just dont know how i would get it to decrease each 2 mins, i have an idea, but i can't seem to get it to work.
thanks for the help

Keep a variable, health_decrease_time that represents the last time the health was decreased.

Turing:

var health_decrease_time := 0
loop
    if Time.Elapsed - health_decrease_time > 120000 then
         health_decrease_time := Time.Elapsed
         health -= 25
     end if
end loop

Care to tell me why the variable health is a string? It should be an int.
