the code to calculate the interpolation

1. First calculate the speed

speed = (currentTime - startTime) / (endTime - startTime)

frame = Date.now()
const speed = (frame - positions[0].frame) / (positions[0 + delay].frame - positions[1 + delay].frame);
  • The interpolation factor speed represents the position between the two most recent positions in the positions array.
  • frame is the current frame of the game.
  • positions[0].frame is the frame of the most recent position in the positions array.
  • positions[0 + delay].frame and positions[1 + delay].frame are the frames of the two most recent positions, with a delay offset.
