March update, getting older soon...

HFB game experiment and BB framework updated:

• BB
• TSpriteEngine, fixed some minor Z issues
• New TSpriteEngine.SpritesAt() that returns the list of all sprites inside a rectangle 
• New ISurface.GetRectangle()
• New ILayer.GetSurfaceAt()
• TSpriteEngine.Render() improved (list removed)
• TAnimationSprite now updates the current sprite before testing collision.
• TAnimationSprite.AnimationName now accepts an empty string (meaning that no animation is set)
• gsPause removed from TGame state, now it is a variable
• Fixed some bugs in the collision system
• New ISprite.SetOnDie()
• TSoundFactory now stores as cache IBuffer (not TSound)
• TQueue<T> improved
• TPolygons removed (didn't make sense)
• Remove all TSprite method related to pointers for surface access since all of them can be done via GetSurface
• TSuperSprite removed (never used/tested)
• TInterfacedObjectEx = TObjectEx
• Surface cache is now searched per index rather than hash
• Buffers are finally sorted properly and selected automatically via hash (property SortBuffers, False by default)
• Surface cache in sprite engine improved
• TPolygonEx.GetHash() improved
• New TPolygonEx.HasAlpha() (used for polygon hash so now we only have 0 or 1, not 0..255)
• Render buffers now clean better the D3D stages
• Some primitives were not filling properly the Z render buffer
• Many memory leaks removed!, TAnimation,,TSpriteEngine ,TSpritePool ,TLayer ,TDummySprite ,TCollision ,TSurface2Poly ,TSurface ,TPolygons ,TLogHandler ,TSingleton ,TRenderBuffer ,TSoundFactory ,TEvents , TObjectPool, TConcurrentDictionary, TEvents

• HBF
• All game sprites are inherited from TElement 
• New platform that can rotate around an axis
• THero slope code refactored
• New sprite var SLOPE
• TGameSprite.IsDieAttribute() that accepts a cell
• New prizes "Time", "Kill Them All" and "Immunity" (bitmaps, units and classes)
• TGameSprite CreateItemAt() renamed to ConvertTile2Item()
• When hero dies on top of a moving ball, the ball stops
• THero.IsCollisionBottom() code cleaned
• New element Rainbow (a bit silly just testing)
• New enemy Titan
• Hero now frees the samples (memory leak)
• Some new samples (New metal sound, Titan uses it)
• Some new music 
• Removed some unused units 
• Improved TSoundDispatcher, now all sounds are played via this class
• Pause now pauses all playing sounds
• Lava and water are not longer treated as solid so some enemies can move inside, like Titan
• New SpriteFactory (file and class) (all sprite creation move to TSpriteFactory)
• Pixel shader used then pausing enemies via pickup 
• Hero cannot pickup coins when dying
• Background does not longer move 
• Background is now freed (memory leak)
• SpriteEngineLayer2 is now freed (memory leak)
• TSpriteFactory is now freed (memory leak)
• Fixed a double free class with rotating platforms
• New classesTNonGravityElement and TNonGravityEnemy, some enemies and elements inherit from them.
• New enemy Chandelier 
• All sprites now behave like hero (they interact with the environment since many functions were moved from THero to TGameSprite)
• Ray more realistic (...)
• Blob side collisions improved
• Bomb side collisions improved
• Titan side collisions improved
• All tiles can now be "moving tapes" (before they were sprites)
• When starting and finishing a level a fading effect is used 

Summer is coming soon!
