Scripting help, Global offset vs Agent

[kira Alena]

Hey there. I Am working on an item that detects users to the left of the agents x axis. 

To simplify it a bit:

Lets say that I have a prim in world. I would like the attachment to be able to return how many meters that the position (of the object), if from the direction the user is facing.

eg, an offset <0,3,0> +3 meters would be = the object is 3 meters to the left of the direction that the user is facing. 

I am a little stumped at this point, so I hope someone can help.

have a look at what Wulfie has shown here:

the value returned in direction.y is the right angle distance between the origin plane and the target point/vector
