I get an error on debugscript "attempt to perform arithmetic on global 'rz' (a nil value)" on the line:

local collision, cx, cy, cz, element = processLineOfSight(lx, ly, lz, rx, ry, rz+1, true, true, true, true, false, false, true, false, vehicle or value) 

Which is line 60 in the lua script above.

[Castillo]

You haven't got these variables at all, that's why the error.

I guess rx, ry, rz is the element rotation.

I added the missing variables.

local rx, ry, rz = getElementRotation(value)

Alright, haven't been able to test that properly Solidsnake14 but it might've fixed.
