// This class has to be able to handle server TPS being lower than client FPS.
// While still having perfectly responsive movement client side.
// We do this by keeping track of the exact sub-tick values that inputs are pressed on the client,
// and then building a total movement vector based on those sub-tick steps.
//
// We keep track of the last sub-tick a movement input came in,
// Then when a new input comes in, we calculate the fraction of the tick the LAST input was active for
// (new sub-tick - last sub-tick)
// and then add to the total-this-tick movement vector
// by multiplying that fraction by the movement direction for the last input.
// This allows us to incrementally build the movement vector for the current tick,
// without having to keep track of some kind of list of inputs and calculating it later.
//
// We have to keep track of a separate movement vector for walking and sprinting,
// since we don't actually know our current movement speed while processing inputs.
// We change which vector we write into based on whether we were sprinting after the previous input.
// (well maybe we do but the code is designed such that MoverSystem applies movement speed)
// (and I'm not changing that)
