PostFX Library

A couple of weeks ago I set about learning how to create and add new post effects to our game. This quickly grew into a postFX library which I decided I would post as a resource - everybody loves Post Effects, right? :)

Installation is simple. Download and unzip this file into your game folder (it should drop straight in).

There are just a couple of small additions to existing files:

In Scripts/client/init.cs -- after exec("art/gui/StartupGui.gui");

exec("art/gui/guiPostFX.gui");

In Scripts/client/default.bind.cs -- at end of file:

// postFX Gui
function postFXGuiToggle(%val)
{
   if (%val)
   {
      if (guiPostFX.isAwake())
      {
         Canvas.popDialog(guiPostFX);
      } 
      else 
      {
         Canvas.pushDialog(guiPostFX);
      }
   }
}
moveMap.bind( keyboard, "alt m", postFXGuiToggle ); // replace with keystroke of your choosing

So what effects have we got then?

• Pixelation
• Blurred Vision
• Dream View
• Cross Stitch
• Posterisation
• Night Vision
• Chromatic Aberration
• RGB sliders
• Zoom Blur (credit to Tuomas Kaukoranta for this one)
• Negative
• Black and White
• Monochrome
• Edge Detection

Anticipating the inevitable "video else it didn't happen" comment (Steve...) I made this:


I can't take credit for writing most of these from scratch - they are mostly a collection of effects that have been ported from glsl shaders found elsewhere on the internet (publicly available). They are all easily tweakable / extendible and hopefully you will use them as a starting point (the night vision shader, for example, definitely needs a bit of work).

Usage
Press alt-m in-game to bring up the control GUI. The effects can of course be controlled via script - just see PFX_Library.cs for the PostEffect names as well as the variables to control the look of them.
