alternative to sleep()

[i8bit]

Is there an alternative function instead of doing let's say this:

PHP Code:

function onCreated(){
 this.chat = "Set 1";
 sleep(1);
 this.chat = "Set 2";
 sleep(1);
 this.chat = "Set 3";
 sleep(1);
 this.chat = "Set 3";
} 


I'm scripting a baddie and I have an attack skill that does multiple damage functions set up similar to what's above. But my baddie glitches in weird ways when ever I use sleeps() so I was wondering if there were any alternatives to write what I have.

I need an
Action()
Wait(0.2)
Action()
Wait(0.2)
so on
