Dear All

I've written a basic SP script with three objectives. It all works perfectly until the player meets up with a friendly 'prisoner' Miller. The friendly moves to the player and follows the player - no problem. But as soon as we encounter enemy AI and the firing starts the whole thing freezes and I get this error message

Script Error: Cannot cast 'NIL' to float
wait self.waittime (global/friendly.scr,1172)

Script Error: Cannot cast 'NIL' to float
while (iSalive self) (global/freindly.scr,228)

ERROR: Command overflow Possible infinite loop in thread

The full script is pasted below. Anyone got any ideas as to what I'm doing wrong?? Thanks in anticipation.

Regards

Otto

should be It's kinda weird the friendly.scr has no protection for this though. If you notice the scripting overhead really slows down the game, it could be a good idea to increase the waittime.

This is even better:

$friendly thread global/friendly.scr::friendlythink
$friendly.friendtype = x
$friendly.distance = xxx
$friendly.destination = $player
//blah blah blah!
end

and use 1 2, 2 2, 3 2 for add objectives.

Why would that be better?

You forgot to set a waittime and that's what caused Otto's error. The .destination variable is overwritten by friendly.scr, so it really doesn't matter what you set there.

I mean, (don't flame me!!!!!), it's the same after all, that's the way i write it.

The waittime was for him to add.

I'm only heating you a few degrees

Thanks for your help. Much appreciated. It works a treat.

Cheers
