Timer Issues

ok, im working on a game right now and im having some problems coming up with a reliable way to keep track of n timers without screwing up the screen, and noticeably slowing down the game, at first i thought of a procedure, but couldnt get it to work quite right, so i went to a process, but its still not working, heres what i have so far, if anybody could help it would be much appreciated Very Happy

Turing:

process timer (amount : int)
const times : int := amount * 1000
var tim : int := Time.Elapsed
var tim2 : int := Time.Elapsed - times
loop
cls
put "Time Before Impact: ", round ((tim - tim2) / 1000)
View.Update
tim2 := Time.Elapsed - times
if tim - tim2 <= 0 then
put "BOOM"
end if
exit when tim - tim2 <= 0
end loop
end timer

I think the code here is mostly right, i just think there's a problem with the way this interacts with the rest of your code. I see that you are using this process to not only keep track of the seconds, but also to display the timer. Since this is a process, and you are using View.Update, this will reign hell upon earth. Why process are evil. I reccomend that instead of having a process like this keep track of your timers, and take up 50% of your resources per timer, i suggest you develop a way to record Time.Elapsed at a certain point in your code, and then, for every iteration of your main loop, compare the old time to the new Time.Elapsed, until the desired difference is reached(eg. Time.Elapsed - old_time >= 10000 would be a ten second timer). Also, display the timer in your main loop too, so that you don't get any unpredictable flickering when using View.Update.

that View.Update was in there from before when it was a proc, ive read that article many a time trust me. i just had this one process in there for now until i could figure out what was going on with my procs...

Soo.... what's your question?

my question is how can i get that (above code) to allow me to have multiple timers going while still looking at least half decent...

Make an array? Perhaps of real numbers, that you

Start off with this, perhaps:

code:

type timers_type :
record
old_time : real
time_length : real
end record

const TIMER_NUM := 10
var timers : array 1 .. TIMER_NUM of timers_type

cant you just "fork" the process?
