void FloatingImage::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)

Implements GameObject.

Definition at line 38 of file floating_image.cpp.

References fading, and visible.

{
  if(fading > 0) {
    fading -= elapsed_time;
    if(fading <= 0) {
      fading = 0;
      visible = true;
    }
  } else if(fading < 0) {
    fading += elapsed_time;
    if(fading >= 0) {
      fading = 0;
      visible = false;
    }
  }

  //  (void) elapsed_time;
}

void FloatingImage::draw

(

DrawingContext &

context

)

[virtual]

The GameObject should draw itself onto the provided DrawingContext if this function is called.

Implements GameObject.

Definition at line 84 of file floating_image.cpp.

References anchor, fadetime, fading, get_anchor_pos(), layer, DrawingContext::pop_transform(), pos, DrawingContext::push_transform(), SCREEN_HEIGHT, SCREEN_WIDTH, DrawingContext::set_alpha(), DrawingContext::set_translation(), sprite, and visible.

{

  context.set_translation(Vector(0, 0));

  if(fading > 0) {
    context.set_alpha((fadetime-fading) / fadetime);
  } else if(fading < 0) {
    context.set_alpha(-fading / fadetime);
  } else if(!visible) {
    context.pop_transform();
    return;
  }
