| 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. http://www.hi-toro.com/blitz/MotionBlur.rar http://www.hi-toro.com/blitz/MotionBlur.zip Also, please vote for my gallery screenshot at http://blitzbasic.com/gallery/view_pic.php?id=1193&gallery=&page=1 | |||||

| Thanks, This was really good.. |

| 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,2 PositionEntity l_surface,0,0,1 EntityOrder l_surface,-100 ScaleSprite l_surface, 1, 0.75 Global l_texture=CreateTexture(width,Height,1+256) TextureBlend l_texture,2 ScaleTexture l_texture, (Float TextureWidth(l_texture)/Float width),(Float TextureHeight(l_texture)/Float Height) EntityTexture l_surface,l_texture EntityAlpha l_surface,.3 Function l_setAlpha(alpha#) EntityAlpha l_surface,alpha# End Function Function l_update() RenderWorld CopyRect 0,0,width,Height,0,0,BackBuffer(),TextureBuffer(l_texture) End Function |

| Simple, but effective, great job! The Screenshot it awesome! |
| ||
| very awesome! |
| ||
| 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. |
| ||
| um does anyone have the demo for this |
| ||
| can someone refresh the link ? |
| ||
| Does anyone have the demo for this? |
| ||
| link? |
| ||
| ... Obviously, there is no and will never be a link. |
| ||
| 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. |
| ||
| Sent :D |
| ||
| Thanks, daaan -- both links at the top are now working again. It's a really cool effect too! |
