    how do I access 
    Application.current.window
    from a class that's not 
    Main
    (I need to find the width and height)
  • t
    because attempting to results in
    Copy code
    HelloWorld.js:21480 Uncaught TypeError: Cannot read properties of undefined (reading '__window')
    at HelloWorld.js:21480:45
    at $hx_script (HelloWorld.js:22843:3)
    at $hx_exports.lime.embed (HelloWorld.js:22852:2)

    Nvm, I fixed it by setting them in some static init function I have to call at the beginning.

    wtf..? it won't let me send my question
  • t
    I'm having problems with camera movement, basically I decided to make my code more modular instead of stacking everything in a single Main.hx file, but I obviously broke something. (will send code snippets in the next message)
  • t
    So in Camera.hx:
    Copy code
    hx
public static function moveCamera(delta:Float):Void {
        dt = delta;
        var camSpeed = speed * dt;
        if (moveForward) {
            var tgt = front.clone();
            tgt.normalize();
            tgt.scaleBy(camSpeed);
            pos = pos.add(tgt);
        }
        if (moveBackward) {
            var tgt = pos.clone();
            tgt.normalize();
            tgt.scaleBy(camSpeed);
            pos = pos.subtract(tgt);
        }
        if (moveLeft) {
            var m = pos.crossProduct(up);
            m.normalize();
            m.scaleBy(camSpeed);
            pos = pos.subtract(m);
        }
        if (moveRight) {
            var m = front.crossProduct(up);
            m.normalize();
            m.scaleBy(camSpeed);
            pos = pos.add(m);
        }
    }
    In Main.hx:
    Copy code
    hx
public override function update(deltaTime:Int):Void {
        this.deltaTime = deltaTime * 1.0 / 1000.0;
        if (Camera.moveLeft || Camera.moveRight || Camera.moveForward || Camera.moveBackward) {
            Camera.moveCamera(deltaTime);
        }
    }

    public override function onKeyDown(key:KeyCode, modifier:KeyModifier):Void {
        switch (key) {
            case LEFT:
                Camera.moveLeft = true;
            case RIGHT:
                Camera.moveRight = true;
            case UP:
                Camera.moveForward = true;
            case DOWN:
                Camera.moveBackward = true;
            default:
        }
    }

    public override function onKeyUp(key:KeyCode, modifier:KeyModifier):Void {
        switch (key) {
            case LEFT:
                Camera.moveLeft = false;
            case RIGHT:
                Camera.moveRight = false;
            case UP:
                Camera.moveForward = false;
            case DOWN:
                Camera.moveBackward = false;
            default:
        };
    }

    And in the render loop, I'm updating the view matrix with
    Copy code
    hx
view = 
MatrixUtils.createLookAtMatrix(Camera.pos, Camera.pos.add(Camera.front), Camera.up);
  • t
    pressing the arrow keys does nothing, but I double checked if it works or not by a trace
  • t
    And yeah I also made sure I'm updating the uniforms each frame
  • t
    Ok. I fixed it
  • t
    it was something with the getters of the matrices
  • h
    Nothing like refactoring to break stuff 🙂

    @aloof-sundown-95280 Re. that console window when using HL. These are your options: 1. call 
    hl.UI.closeConsole()
    (but the console window will still up for a few moments) 2. change the subsystem of hl.exe from console to window. (See also ) 3. use hxcpp + 
    -release
  • a
    why'd you strike out option 3? 👀
  • a
    option 1 worked thnx
  • e
    likely because while it would work, its probably not the option your looking for
  • e
    "use hxcpp" implies "dont use hashlink"
  • a
    I see, is that just a single command I can use or does it take setup/manual steps?
  • e
    its a different lime target
  • e
    lime [build|test|run] [windows|mac|linux]
  • a
    oh that, it didn't work for me so I guess option 3 is a no-go
  • a
    errors test/build for html5 with that, any way to check if hl?
  • h
    I think `#if hl`works doesn't it ?
  • a
    where
  • h
    In your hx file where you use this code
  • a
    oh well that was bad lol
  • a
    I see, thnx
