  I think the 'toon' effect that comes with C2 works by posterizing the image and adding a black edge.

  I altered some of the parameters and managed to remove the lines....but, when the image is resized

  the lines re-appeared.

  Have you tried using the 'posterize' effect instead with the level's set to about 8 or 10.

  You wont see any lines when you resize.

  Try renaming the effect and see if it works?

  You will have to change the xlm file to match!

  'I dont understand why, but i copied the fx files to the effects folder.

  But when i open the capx im notified the effects are not installed.

  Any idea why?'

  Not sure why this would happen...try creating an new project and adding the effect your sprite object.

  'Alright so I was looking at the Basic Static, trying to take into account low-rez scaling. So instead of applying noise to every single pixel, apply noise in such a a way as to take into account each scaled pixel in a pixel-art game.'

  Iv'e not had much(any) look in coming up with a solution to your question.

  I think the calculations for the noise are done before the main part in the shader.

  Have you tried using the 'step noise' part instead of the 'basic 'noise, it might resize better.

  The only other thing I can think of is using a pixellated effect with a animated parameter.

  DeformGlsl effect

  An attempt to convert the Shadertoy 'Deform' effect by iq (2009).

  Animated polar transformation effect or pretty patterns.

  What you should see!

  

  The code is similar to the webglSphere effect so it might not work on some systems.

  Does the effect need to animate / change over time?

  Which of the Noise 'types' are you wanting to use for your game?

  The effect is a collection of different 'types' but I have individual versions of each of them.

  Have you got a screenshot, picture or mockup 'with and without the effect' you could post.

  Have you got any sketches/concept images for your game?

  Do you want a simple side scrolling 'endless runner type game, or something more advanced?

  A 'SpiderMan Unlimited' type game could be done with 'Rojo Mode7 effect', and

  'Rex Mode7 behaviours' but its not easy.

  ( see screenshot)

  

  (Yes I did steal some graphics to make it )

  Here's the link my friend-

  https://github.com/electronicwhisper/pixel-shaders

  OR- https://github.com/electronicwhisper/pi ... -pages.zip

  I don't think he ever released a 'finished' version of the book, but the download contains loads

  of examples/ ideas / tips.

  If you want help converting any to work in C2, let me know.

  Do a Search for 'Toby Schachman GLSL pixel shaders'

  His Github page has an interactive book/ shader editor you can download and run offline.

  I'm still working on a solution.

  Have a look at the following -

  https://dl.dropboxusercontent.com/u/22173473/Rotatingsphere.rar

  Gigatron helped me with the above code, so it might render better?

  Let me know if it works ?
