I'm using netwire to build a game; one of the things the player can do is move around using WASD. I want to use key *events* as the 'basis' of my wires, not the entire state vector of the keyboard so that, for example, a press event on D increments the velocity by (200, 0) and a release event decrements it by that much. However, this has the problem that I can't actually get the velocity unless I have an event to feed into the wires, which means I can only update the screen when the user presses or releases a key. While this might make for interesting gameplay, it's not what I want. is the right thing to do to make the input something like a Maybe KeyEvent instead, and pass in Nothing whenever I want to get output without an event for, e.g., a render?
