void PowerUp::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 85 of file powerup.cpp.

References Physic::get_movement(), MovingObject::movement, no_physics, and physic.

00086 {
00087   if (!no_physics)
00088     movement = physic.get_movement(elapsed_time);
00089 }

void PowerUp::collision_solid ( const CollisionHit & hit ) [virtual]

this function is called when the object collided with something solid

Reimplemented from MovingObject.

Definition at line 41 of file powerup.cpp.

References CollisionHit::bottom, Physic::get_velocity_x(), CollisionHit::left, physic, CollisionHit::right, Physic::set_velocity_x(), and Physic::set_velocity_y().

00042 {
00043   if(hit.bottom) {
00044     physic.set_velocity_y(0);
00045   }
00046   if(hit.right || hit.left) {
00047     physic.set_velocity_x(-physic.get_velocity_x());
00048   }
00049 }

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

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