How do I manipulate the arc in llSensor to get it to detect only a height of 10m? In other words, I want to know if an agent is within this 50x26x10 box.
The 50m X-axis is fine, I don't care about the Y-axis, but I need the Z-axis detection to be only 10m high.
Alternatively, how can I llGetPos on the detected agent, so I can then filter?
Regards,
Adam

You may want to look at placing sensor prims... if the box is stationary... and have them use llVolumeDetect().
The alternative is to use the sphere-shaped range that llSensor has, and then check llDetectedPos(n) of the detected targets to see if it is within the x,y,z box you want to check.
Hope that helps! =D

Not an answer to your question but I'll post it anyway.
To solve the X,Y range to exactly cover my land-square only, I used a combo of llSensorRepeat and llOverMyLand-function. Pretty useful. Just make the sensor circle bigger than you land then discard all keys that are not over your land.
Not sure if there's any agent-altitude-function in LSL, that would solve it.

Ah yes! Jopsy added the missing command  There's your soloution. Make a sphere large enough to cover your land. Then add llOverMyLand to verify XY and llDetectedPos to verify Z. Should work |

Thanks Jopsy! From: someone

Yes, that was my backup plan, but it seems a little inelegant From: someone

That's exactly what I was looking for! For some reason, llDetectedPos had evaded my searching on the wiki. Thanks again Jopsy, I'm sure this will work fine. Woopsy's llOverMyLand suggestion is a good one, and I have used it in a visitor sensor I built, but in this case it wont' help. Woopsy and Jopsy, thanks for the helpsy |
