how do I tell the program to use a function only every second

how do I tell the program to use a function only every second - 01/19/13 18:47

Hi,

I want to save the postition of the player every second of the game into a txt file. This works when I use the function save(); in my main while(1) loop.

But it saves the postition every 20th or so of a second - much to much data for me.

How can I say "use save(); only every 1/2 sec"?

Thx in advance!

By using wait with negative values.

Code:

wait(-10); // waits 10 seconds

I know and tried that, but it doesn't help me because I don't want the program to wait ten seconds - I want something to happen every x seconds. How do I do that?

while(1)
{
error("dafuq, why does this even work?");
wait(-1);
}

Maybe you want to run a save-loop run in a seperate function:

Code:

void SaveLoop(var wait_time)
{
	while(1)
	{
		save();
		wait(-wait_time);
	}
}

f.e. call SaveLoop(2); once and save(); gets called every 2 seconds without affecting the rest of your code.

Thank you very much! I tryed something simmilar, but my mistake was to call the function in my while(1) - so it was called every few miliseconds. But now I moved it to main and it does exactly what it should! Thanks again!

So I did, but failed to find there anything that would help me. Could you direct me to the part of the information I might have missed that would have helped?

I think Workshop 10 - Entities is the best one for this. Workshop 2 and 3 are also related to the issue.
