Hi,

If I specify the following for scan_entity:

Code:

---

while(1)
{
    temp.pan = 60;
    temp.tilt = 360;
    temp.z = 100;
    scan_entity(my.x,temp);
    wait(1);
}

---

Is the 360 .tilt value supposed to allow you to scan 360 "up/down" like the following picture?

If I use 360 for .pan, then it works like it should...or like I think it should , but with 360 for .tilt, scan_entity does not detect me when I'm behind...only in front. Is this how it works?

I'm working from memory, so am not 100% sure here -- I believe that 'tilt' will max out at 180 (tilt/2 degrees up and tilt/2 degrees down from the vector described in the 'from' array given to scan_entity()).

Thus, tilt=180, pan=180 will describe the same hemisphere that tilt=360, pan=180 does.

Thanks,

where did you get that info? I don't doubt your response, it's just that I would like more detailed information
on how scan_entity works, since I wrote this little "tool" to show the scan cone...I'd like for it to be accurate.

Edit:
Actually, I've updated my little tool since that last image was taken...can you look at the following
link (scroll to the bottom) and tell me if the scan cone reprentations look right? ...if you know

I really like that dtt_scan_area(), great idea. The program looks like it would be very useful.

thanks!

Feel free to use it
