Member Function Documentation

void GrowUp::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 31 of file growup.cpp.

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

{
  movement = physic.get_movement(elapsed_time);
}

void GrowUp::collision_solid

(

const CollisionHit &

hit

)

[virtual]

this function is called when the object collided with something solid

Reimplemented from MovingObject.

Definition at line 37 of file growup.cpp.

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

HitResponse GrowUp::collision	(	GameObject &	other,
