Description : This is a very small lib that with tweaking can do some really neat things. I have a demo that you can download which has complete source and a simple example.

 Excellent effect, very nicely presented.  I'd already given the gallery image a 5/5.   ...and thanks for the preview!  :)

 Cool effect!I was experimenting a bit and got it to work with other width/height values than 640x480, and the sprite is now 1 unit away from the camera so you don't have to make the CameraRange near# value as small:Global l_surface=CreateSprite(camera)Global width=GraphicsWidth(),height=GraphicsHeight()SpriteViewMode l_surface,2PositionEntity l_surface,0,0,1EntityOrder l_surface,-100ScaleSprite l_surface, 1, 0.75Global l_texture=CreateTexture(width,Height,1+256)TextureBlend l_texture,2ScaleTexture l_texture, (Float TextureWidth(l_texture)/Float width),(Float TextureHeight(l_texture)/Float Height)EntityTexture l_surface,l_textureEntityAlpha l_surface,.3Function l_setAlpha(alpha#)      EntityAlpha l_surface,alpha#End FunctionFunction l_update()   RenderWorld   CopyRect 0,0,width,Height,0,0,BackBuffer(),TextureBuffer(l_texture)   End Function

 Cool :)Has anyone tried adjusting this for multiple cameras by the way? e.g. 2 player split screen. Guess its a case of having x2 sprites one per cam etc.

 Hey all!I still have the code for this somewhere in my gmail account. if you would like, Send an email to dan.wooden@... and I will reply with the demo/code.

 I just noticed I was hosting this at one point, but a lot of links died when I changed web host. I'd be happy to put it back on the original link if you want to email it to me, daaan.


daaan(Posted 1+ years ago)

 Sent :D

 Thanks, daaan -- both links at the top are now working again. It's a really cool effect too!
