Before this change, input states were reset for each frame. When FPS is bigger than TPS, the input state was reset more often than expected and then some inputs were missing. This change fixes the issue by resetting input states not for each frame but for each tick. This change also updates some comments of the input API. Updates #2496 Closes #2501
