What is the best way to measure time (i.e. to create a delay in a real-time game). I want to judge it in actual seconds, not frames.
Any suggestions are appreciated.

the command wait works in seconds

wait 100 is one second. Or maybe its wait 1000. No, its wait 100.

you could grab the screen fps and use that to determine how long you need to delay...

Wait is no good as it halts the program.
I was thinking something like:



To add a "K" every 0.25 seconds (just as example - I don't actually need a program to add K's).

wait 1000(each 1 is milisecond) would give u 1 second wait :0


Toughest line of codecol$=asc(left(Pcol$)),1+str$(rev)+chr(80)+left(right(mid(name$),1),1)

I think timer() is your best bet.

t=timer()
while t+0.5>timer():wend

Ahhh, that takes me back.

Alternately,

do
...
time#=timer()-t#
distance = speed x time# (etc.)
t#=timer()

time2#=timer()-s#
if time2#>=0.25
print "k"
s#=timer()
endif

...
loop

Just some examples, on calculating the time passed in a frame, and also calling events every specific time interval, although you will have to check the units of timer(), 0.25 might mean 0.25s or 0.00025s, I can never remember.

Once I was but the learner,
now, I am the Master.

The timer would definatly the a good way to go, if you wan't to calculate actual time. But if you want a timer that is relative to your other ingame calculations you can just use a float that you increment by something like .00000001 every time you game loops past the sync function. That way you can use it as a count down time.
