hooks in KSP classes

[Wheffle]

I'm not a very seasoned coder, and much less so in C Sharp, and even less so with KSP modding. Some systems in KSP are easy to mod and are obviously set up for modding, like part modules and such. Others seem, to my untrained eyes, locked up very tight.

Specifically I'm looking into intercepting method calls from stock classes and running my own methods either before or after. I believe that's what a hook is, correct? Is this possible?

More specifically, I'm trying to catch the calls that turn on the resource overlays and either modify the textures or give them new textures. I'm having a hard time finding a way to do this without doing some kind techno circus routine involving checking texture changes every game update.

Thanks in advance.
