as a newbie I feel very lost with the raysensor. I'm supposed to use is it as example for a laser sensor plug-in. So I tried to understand the sourcecode of the raysensor, but I really can't handle it..

Can anyone help me, describing the main functions of the sensor and explaining how the sensor is working? and furthermore maybe how I use it as plugin (which things I can change with parameters, as angels etc.)

thank you in advance!
