[Deibos]

So, i want to know how to make a script like this. Or if someone knows/has a script like this.

[quadro]

var time = 0, line = 0;
var lines = [
    "line 1",
    "line 2",
    "line 3"
];

on update:
var curTime = new Date().valueOf();
if (curTime - time > 1000 /*delay in ms*/) {
    mc.thePlayer.sendChatMessage(lines[line++ % lines.length]);    
    time = curTime;
}
