Layer.getscalex

Layer.getscalex(layername:String):Float;

Get the horizontal scale of a layer only. Default is 1. To get the vertical scale, see Layer.getscaley. Also check out: Layer.getscale, Layer.scale, Layer.scalex, Layer.scaley, and Layer.scalexy.

• layername: The name of the layer to check.

Example:

import haxegon.*;

class Main{
  function init(){
    Layer.create("foreground");
    Layer.attach("foreground");

    //Set the scale of the "foreground" layer to half horizontal, double vertical.
    //Pivot around the centre.
    Layer.scalexy("foreground", 0.5, 2.0, Gfx.CENTER, Gfx.CENTER);
      
    Layer.drawto("foreground");
    for (i in 0 ... 200){
      //Draw 200 random circles on the "foreground" layer
      Gfx.fillcircle(Random.int(0, Gfx.screenwidth), Random.int(0, Gfx.screenheight), Random.int(50, 80), Col.hsl(Random.int(0, 360), 0.5, 0.5));
    }
    Gfx.drawtoscreen();
  }

  function update(){
    //Press ARROW KEYS to change the scale of the "foreground" layer
    var horizontalscale:Float = Layer.getscalex("foreground");
    var verticalscale:Float = Layer.getscaley("foreground");
      
    if (Input.pressed(Key.LEFT)){
      Layer.scalex("foreground", horizontalscale * 0.9, Gfx.CENTER, Gfx.CENTER);
    }else if (Input.pressed(Key.RIGHT)){
      Layer.scalex("foreground", horizontalscale * 1.1, Gfx.CENTER, Gfx.CENTER);
    }
    
    if (Input.pressed(Key.DOWN)){
      Layer.scaley("foreground", verticalscale * 0.9, Gfx.CENTER, Gfx.CENTER);
    }else if (Input.pressed(Key.UP)){
      Layer.scaley("foreground", verticalscale * 1.1, Gfx.CENTER, Gfx.CENTER);
    }
  }
}
