cycle servo angle. [is there a way to cycle a servo's angle by a sett degree?]

[racsumsar123]

is there a way to cycle a servo's angle by a sett degree? for example, I'm trying to build a rotating missile rack, and basically i want to be able to press an action group once to turn the rack 90 degrees, and then when i press the action group again the servo should turn another 90 degrees in the same direction.

Welcome to the forums @racsumsar123, your question has been moved from Tutorials to GamePlay Questions.  Somebody should be along shortly with the answer.

I have a feeling that this will require the KAL controller, but unfortunately I have zero knowledge of how to use that thing.
