<DIV dir=ltr><FONT size=2 face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=Arial>Mm, the Sleep is only called when the avatar takes place in the vehicle not otherwise.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=Arial>So before any movement over the vehicle the code that contains the Sleep commands has already been executed.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=Arial>And of course you would expect the script to continue after a small delay and that does not happen.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=Arial></FONT> </DIV>

<DIV dir=ltr><FONT size=2 face=Arial><FONT size=3 face="Times New Roman">I've got a simple car (works fine in SL).<BR>I've created a small LSL script (see below) that listens to channel 9 for information about speed and direction. The script inputs this into the standard physics commands to move and turn the car.<BR>Because I want outside (of OpenSIM) control of the car, I've created a small C# program that simply types the speed and direction into the chat box (/9 speed_direction). This because a HTTPrequest from LSL is limited to about 1 call per second and that is too slow.<BR>The whole setup seems to work. The car moves and turns smoothly, BUT after about 5 secs (give or take) moving the script stops responding and the vehicle stops. After StandUp-Sit it resumes for another 5 secs.<BR>If the vehicle does not move, the script keeps running.</FONT><BR></FONT></DIV>
