llSensor down positive y axis

Howdy,

Is there a way to get llSensor to look down the positive y-axis?
Or anything other than positive x?

Gracias,

Whoop, I figured it out.

This might be well known already, but if you want your creature
to have its local coordinate system point down a particular axis,
have the root prim, that is, the last prim you select when linking
the whole thing together, oriented toward that axis.

So, in my case, to get llSensor to work down the x-axis and have
that match the front of the creature, I set the rotation of the root
prim to <0, 0, 0> while the creature itself points down the positive
x-axis.
