Alternative to sleep()

[brokk]

I was wondering if there was an alternative to the sleep() function.

If I'm not mistaken, sleep pretty much just pauses the functions of the script.

DoThis;
DoThat;
sleep(1); <-- pauses for one second
DoSomethingElse;

I know it's a dumb question but I'm running into problems in my movement using sleep so I need another code that pauses a line in script.
