Laser Pointer Receiver Distance

[sharpish]

I was wondering if anyone can help me. I've seen on tutorials how to link up the LPR to the x, y, z and distance to screens. However on my LPR and on gmod wiki it shows
x
y
z
active
pos
ranger data
I've been playing around now for sometime now trying to get it to display the distance when using the laser pointer, but I can't seem to get it. I've tried using an expression 2 containing pythagorus but still nothing

I'd love some help because I'd like to try and make a laser targeting cannon using projectiles

[jacoby6000]

to get distance, just take the point that the laser is hitting (pos) and the point that you want to get its distance from, then run V:distance(V)

Thanks

So I'm after the distance between the receiver and where the laser pointer is hitting

[jacoby6000]

get the recievers position using an entity marker

@inputs Receiver:entity Pos:vector
@outputs Distance
Distance = Receiver:pos():distance(Pos)

or use a wirelink

@inputs Receiver:wirelink
@outputs Distance
runOnTick(1)
LaserPos = Receiver["Pos",vector]
ReceiverPos = Receiver:entity():pos()
Distance =  ReceiverPos:distance(LaserPos)

Either place a GPS receiver right next to the receiver, or use a target finder next to the laser pointer receiver to find its GPS coordinates (you could also use an entity marker and a gate that gives the position).

Cheers, great help

I've not had any luck with the expression

This is what I'm aiming for File:Laserpointer.jpg - GMod Wiki

How would I use the GPS Azrael? I've only ever used it with a Target Finder for a missile

Your explanation of 300mw green laser pointer also helped me ,thanks a lot.

Does anyone know why 'Distance' was removed from the laser pointer receiver?

Can't you just wire a ranger distance gate to the "ranger data" output? Alternatively:

@inputs R:ranger
@outputs Dist
interval(->R)
Dist = R:distance()
