void Coin::update

(

float

elapsed_time

)

[virtual]

This function is called once per frame and allows the object to update it's state.

The elapsed_time is the time since the last frame in seconds and should be the base for all timed calculations (don't use SDL_GetTicks directly as this will fail in pause mode)

Reimplemented from MovingSprite.

Definition at line 73 of file coin.cpp.

{
  // if we have a path to follow, follow it
  if (walker.get()) {
    Vector v = from_tilemap ? offset + walker->get_pos() : walker->advance(elapsed_time);
    movement = v - get_pos();
  }
