How can I apply shader for all screen?

[bogdan-ov]

I need to apply a shader to the game screen and manipulate with the screen somehow. Like DisplacementFilter in pixi.js

I tried to do so, but it didn't work

...

class SomeShader extends FlxShader {
  @:glFragmentSource(...)

  public function new() { super(); } 
}

class Main extends Sprite
{
  public function new()
  {
    super();
		
    var game = new FlxGame(0, 0, PlayState);
    game.shader = new SomeShader();
		
    addChild(game);
  }
}

Advance thanks!

Something like this:

import openfl.filters.ShaderFilter;
...

class SomeShader extends FlxShader {
  @:glFragmentSource(...)

  public function new() { super(); } 
}

class Main extends Sprite
{
  public function new()
  {
    super();
		
    var game = new FlxGame(0, 0, PlayState);
		
    addChild(game);
  }
}

class PlayState {
  ...
  override function create() {
    var shader = new SomeShader();
    FlxG.camera.setFilters([new ShaderFilter(cast shader)]);
  }
}

I think there might be more in the source code of this demo -> https://haxeflixel.com/demos/BlendModeShaders/
