Documentation

_SpriteInit($hGuiHandle, $iNumberOfSprites = 100, $iFps = 60) - You must call this to initialize the sprite engine. If you set $iNumberOfSprites too low some sprites may not get created.

_SpriteRunning($iRunning) - if you set this to 0 the sprite engine will pause itself. If you set it to 1 guess what happens

_SpriteCreate($sPicFilePath, $iX, $iY, $iWidth = "", $iHeight = "", $vStyle = "", $vExStyle = "") - Creates a sprite. Returns the sprites handle or 0 is there are no handles avaliable

_SpriteDelete($hHandle) - Just guess what this does.

_SpriteSetMovement($hHandle, $iSpeed, $iAngle) - sets the sprites movement. the speed is the number of pixels it moves per frame. The angle is the direction in which it moves

_SpriteSetCoords($hHandle, $iX, $iY) - sets a sprite's coordinates

_SpriteCheckCollision($hHandle1, $hHandle2) - returns 1 if the two sprites are touching each other

_SpriteGetCoords($hHandle) - returns a two element array. [0] - x position [1] - y

_SpriteGetSize($hHandle) - returns a two element array. [0] - width [1] - height

_SpriteFollowMouse($hHandle,$iFollowMouse) (UNCOMPLETED) if you set this to 1 the sprite will follow the mouse on the x axis

_SpriteGetMovement($hHandle) - returns a two element array [0] - speed [1] - angle

Hope you enjoy it!

I'm working on a breakout example for this

Edit: for the pong example you need to create 3 files.

Red.bmp

Blue.bmp

and Green.bmp

they cna be of any dimensions. put the color into the file. They are too big to upload to the forums and i'm too lazy to sendspace it.

_SpriteEngine.au3

pong.au3

I get

C:\Temp\_SpriteEngine.au3 (137) : ==> Subscript used with non-Array variable.:

$Return[0] = $pos[2]

$Return[0] = $pos^ ERROR

[LiveOnTheFly]

I get

That means the sprite wasn't created properly. Silly me forgot to upload the red green and blue.bmp for the pong

Edit: it's too big to upload so just create the bmps your self

can you use other formats like JPG or does it have to be bmp for this. The example is okay...

A suggestion, for what it's worth, would be to use A.Percy's au3Irrlicht script and billboards. You immediately gain the advantages of having 3D rendering and special effects (lighting) and using any image format, as well as neat transparency and multiple rendering engine options, with all the performance benefits that come with it. It's really easy to use, and a sprite engine built on top of irrlicht would rock.

Anything that GuiCtrlCreatePic can handle.
