    like you want to convert a 3d matrix into a 2d matrix that would result in the same rendering when projected? yeah I think that's not possible
  • w
    otherwise why would 3d matrices even be used if 2d ones could do the same
  • e
    Cos it has different ways to manipulate a 3D matrix that you would want to apply to an image
  • e
    For example, there's hsl, hsv, cyk, but they aren't replacing rgb
  • e
    You can parse them together to have more spiced things, but you can parse them
  • e
    And since 3D matrix looks like an extends Matrix to some capacity (not the class, but the matrix) then I thought that it would be possible to parse it somehow

    is there any way to add an outline to a 
    TextField
    ?
  • b
    @curved-tiger-81069 you can try https://github.com/loudoweb/openfl-shaders/blob/master/openfl/shaders/Outline.hx like that : 
    text.shader = new Outline(2, 0xff0000);
  • b
    but for now the quality parameter is disabled, so it's better to use very thin outline
  • b
    depending on your outline size, you may need to use it as a shaderFilter instead + setting __topExtension, __leftExtension, etc. I'm looking for a better solution
  • b
    (because it will be cropped to the textfield size)
  • b
    I think you can also use a GlowFilter
  • b
    well, I have just push a new OutlineFilter in my lib, so there won't be cropping issue anymore. But I'm still working on improving the quality dynamically. If needed you can change the ANGLE_STEP variable.

    :0 thx!

    I remember seeing something a little while ago about 3d spatial audio. Anyone know if this is built into OpenFL? I might have seen it about Lime. Any example code out there?
  • e
    iirc you can adjust the l/r panning manually
  • r
    Looks like 
    lime.media.AudioSource
    has a 
    position:Vector4
    property. But there is no documentation at all. So that might be something useful that someone worked hard on, but no way of knowing unfortunately.
  • r
    it looks like OpenFL uses the 
    position:Vector4
    property to adjust left/right stereo pan:
    Copy code
    haxe
var position = source.position;
position.x = pan;
position.z = -1 * Math.sqrt(1 - Math.pow(pan, 2));
source.position = position;
  • r
    that code is from Sound.hx (and SoundChannel.hx) from OpenFL
  • r
    oh interesting! Thanks!
  • c
    this might be a dumb question but why doesnt it let me set something that extends bitmap as a bitmap i know i can just do 
    cast
    but im just curious
  • b
    is electron a newish openfl target?
  • b
    I don't think so
  • r
    Anyone got any idea how I can access the microphone on ios with haxe/openfl?
  • c
    just curious, is there any way of making a function run when a varible is changed?
  • i
    An abstract, class property with a setter, macros combined with an abstract, or maybe an additional type extension (I don't remember if they store state tho).

  • b
    @curved-tiger-81069 you can also use this https://lib.haxe.org/p/bindx2/
  • t
    how do I select a folder through FileDialog/FileReference? I can only select files, but I want to select a folder, so i can e.g - fetch its path and then get the list of files n i

    this might help: https://discord.com/channels/162395145352904705/565569107701923852/1009181009968910507 its worth mentioning that im planning to create a lib (system-utils) with all this stuff neatly wrapped up - it will be a 100% NON-haxeui lib, so you can use it from anywhere: https://discord.com/channels/162395145352904705/162664383082790912/1009555964237729893
