Footsteps and hit moments play twice, or never, after a lag spike or a loop restart

Sounds and effects are tied to moments inside an animation. When the animation clock skips ahead because of lag, or loops around, the naive check misses events or fires them twice. And a newcomer who joins mid-run should not hear a burst of old footsteps.

Why this works

Asking which events fall inside the stretch of time just passed covers every moment exactly once, however long or short the frame was. A window that is open at one end means a moment on the border belongs to one frame only, never two.

When not to use it

Wrong when the sound should follow the actual contact, like a foot that really touches the ground at an uneven height; then fire it from the ground check. Also skip it for effects that must not be dropped after a freeze, such as a hit.
