HBF is not alone anymore, say hello to a new player.

Like a month ago I was thinking, why not add a second player?, but as usual new ideas bring new challenges.

Adding a second player to the game means many aspects of the game have to be modified, like who enters the Shop, how Items are split, some enemies need to decide the proper victim, how to handle when heroes are far away from each other, what do to when one die, change the behavior of the Door, who enters the Fight, rewrite most of the input system, etc.

That was as usual very funny. The most difficult part was to handle the Camera and order of sprites, so I decide so change the 2d engine to be more 3d (visually still the same), so now Camera can play with Z axis, then many Z issues appear..., so I had to revisit all game.

But anyway, the work is done after some tough weeks :-)

Found binaries at OneDrive
  • Now two players can play the game, big improvement
  • Now when a coin is taken it executes a different particle
  • Now levels starts differently

  • Now doors still closed when taking the key and can only be opened by the owner of the key
  • When in two players, if one player looses of lives, then he releases all inventory so that the other player can take it
  • When in two players, if one player looses of lives and the other player has already entered the door, then the level finishes
  • Input reading code optimized
  • Now Fight, Shop and Inventory can only be used by the player that activate it
  • Shop/Inventory/Items code improved
  • Fight changed a bit

  • If hero looses the Rune Fight he also looses his coins
  • Now when finishing level, camera focus and zoom on Door
  • Now aspect ratio can be selected (4:3, 19:9, 16:10), so game should fit properly with all resolutions
  • Camera Lerp now also takes into account Z
  • Drawing air moved from hero to HUD
  • Now heroes are able to push many blocks in a row either vertical or horizontal
  • Some interfaces were not set to nil on destroy

  • Doing a render to target and losing the surfaces does not work, it raises an AV, why?!
  • Sleep properties in Particles now talk about milliseconds rather than steps
  • Lightmaps now also interpolate alpha channel
  • Some internal array improvements (aligned to next power of two)
  • Surface.Blur() quality improved
  • TArrayEx<T> improved

  • Fonts performance improved
  • New TCamera2D.Rotate()
  • Shadow silhouette improved (a bit of blur applied)
  • New TMenu.Find() in order to find menu items and optionally be able to modify them
  • New events for particles OnBefore/OnAfter Create/Tick

New aspect ratio option)

 HBF now is accompanied by his partner ABB (say what?)

Camera zoom out to fit both players (until a certain point)

HBF now in 64 bits!

I had a silly bug (typical one that works on WIN32 and does not in WIN64):

    FillChar(d3ddm, SizeOf(d3ddm), 0);  <-- this line didn't exists
    if Failed(FD3D.GetAdapterDisplayMode(D3DADAPTER_DEFAULT, d3ddm)) then
      raise Exception.Create('Error retrieving display modes');

    FD3Dpp.BackBufferFormat := d3ddm.Format;

So now there is a 64 bits version, I guess only math is faster, but this would be only noticeable when lots of  particles are rendered, but let's see..

Found binaries at OneDrive

Anyway, I also was able to change the following:

  • Now HBF also comes in 64 bits flavour
  • Now Diamond emits light
  • As usual some minor map changes...
  • Some new blurred backgrounds
  • ell/Boom/Chest/Fires/Lava/Mine/Planet are now glowed

  • New toxic particles
  • New excited particles
  • New particles when Hover is excited
  • Magnet also attracts Keys and Scepter
  • New sound failure.wav
  • Gatashi's laser when collides draw some particles
  • Now all mechanic enemies can be excited
  • Now when correcting gravities, moving platforms are take it into account
  • New worm, fits better in the game
  • New bell and shoes, more retro
  • Planet changed
  • Ice floor is now properly applied when gravity is up
  • Snowball now also stops fire
  • Static sprites do not longer correct gravity orientation
  • New warp based on particles
  • New spark based on particles
  • New Achievement "finish labyrinth blinded"
  • Main menu does some new effects
  • Ending now is a bit different (guess what!)

  • Multiplication texture error fixed (not happy about it)
  • Sprite hash for buffers now takes into account shadows
  • New concept TBufferHelper, in order to handle the buffer easier and avoid some double links
  • Removed effects and filters from surfaces (makes no sense, sprites dictate the behaviour)
  • Added surface filter to Materials
  • Fixed massive bug in Move32() POP ESI rather than POP EDI
  • D3D buffer preparation improved (VertexType is now precalculated)
  • Now TFloat is double when in 64 bits
  • New Particle emitter Movement type
  • Stream buffer when decompressing changed from 16kb to 64kb
  • Finally DirectX works in 64 bits
  • New TSurface.ExtractPoints()
  • New TParticles First()/Last()
  • Now particles are able to do formations based on a bitmap

When performance matters

First entry of the year, one month and half later... , found binaries at OneDrive

I've been focus this past two months on improving the performance, in some screens mixing many elements, enemies, particles, lasers, liquids and moving backgrounds was affecting the performance, so I did what I love, to dig into the code and start measuring and comparing, I'm quite happy with the results, now I can throw many particles here and there that performance is not affected.

I did focus on DirectX buffers: hash created only when needed, buffers only sorted when needed, tailor-made drawing triangle functions, RGB to int conversions.

Surfaces are now generated faster when they are in 32 bits.

Also the new TFastPool<T> used in particles it excels, and indexed array for fast access with a pool mechanism in the same structure (maybe I will explained in another post)
