Member Function Documentation

HitResponse SkullTile::collision	(	GameObject &	other,
		const CollisionHit &	hit
	)			[virtual]

this function is called when the object collided with any other object

Implements MovingObject.

Definition at line 37 of file skull_tile.cpp.

References FORCE_MOVE, and hit.

{
  Player* player = dynamic_cast<Player*> (&other);
  if(player)
    hit = true;

  return FORCE_MOVE;
}

void SkullTile::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.

void SkullTile::draw

(

DrawingContext &

context

[virtual]

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

    pos.x += graphicsRandom.rand(-3, 3);
  }
