Connecting locator to texture?

I've got a character with a fairly flat eye, and I was setting up the eye with a locator. I was going to just connect the texture on the eye to a locator using the connection editor, but I can't seem to find what I've got to do. Basically, I want a locator to drive the placement of a simple ramp on the surface of the eye. I tried looking in the driven key menu, but I can't seem to find what I need there, either.

Anyone have any suggestions?

I've never had to solve this problem before, but if you are projecting the texture onto the surface of the eye, then you could just connect the texture projection node to the locator ... couldn't you? If you point constrained the projection node to the locator with maintain offset toggled on for the constraint operation, then you should be able to move the locator and the projected texture should move with it.

at least it works in my head ...

Ahh, okay. The texture on the eye I'm using wasn't projected, actually. I consulted a friend of mine today, and he suggested using a script and showed me how to set that up, but he also recommended using a driven key (which I had tried before). The way I had tried to load the place2dtexture node in the driven box was just totally wrong before, but with my friend's help, I got it loaded.

So basically, I keyed the offset U and V attributes to correspond with the translate X and Y on the locators. If you can't seem to get the place2dtexture node to load into the driven key window, you can go to the attribute editor, go to the offset attribute boxes, and right-click in the box. There's a "set driven key" option there, and it'll load that in the driven box. All you have to do after that is load the locator in the driver window, and key it. So, now it works.

Thanks for your help, though. I don't know, maybe your solution and mine will be a handy reference or something now.
