Camera translations

Hey, thank you for this extremely cool api. After 5 days head banging, I found that I need to take into account the pixi’s renderer resolution in order to make the camera coord conversion to work as it should. Here are the wrapped methods (I am not sure 100% about the z values, because I do not need z at all in my app).

public static toWorld(
        container: Container,
        anchor: Point,
        model: Model
    ): ObservablePoint3D {
        let bounds = container.getBounds();
        let x = bounds.x + anchor.x * bounds.width;
        let y = bounds.y + anchor.y * bounds.height;
        return this.screenToWorld(x, y, model);
    }

    public static screenToWorld(
        x: number,
        y: number,
        model: Model
    ): ObservablePoint3D {
        let worldCoordinates = Camera.main.screenToWorld(
            x,
            y,
            Camera.main.z - model.z,
            undefined,
            {
                width:
                    App.instance.renderer.width /
                    App.instance.renderer.resolution,
                height:
                    App.instance.renderer.height /
                    App.instance.renderer.resolution,
            }
        );

        return worldCoordinates;
    }

    public static worldToScreen(
        x: number,
        y: number,
        z: number = Camera.main.z
    ): Point {
        let worldCoordinates = Camera.main.worldToScreen(x, y, z, undefined, {
            width:
                App.instance.renderer.width / App.instance.renderer.resolution,
            height:
                App.instance.renderer.height / App.instance.renderer.resolution,
        });

        return worldCoordinates;
    }

I hope this helps and it will save time to someone using your api.

Thanks, Ivan

Thank you, it is merged, I will test it when I go back to home. -edit- Yes, it works now. The white rect is not centered on zoom change, but this is not important, because the model and pps works as they should.

I guess we could close this now, thank you again 😉
