Layer.rotate

Layer.rotate(layername:String, rotation:Float, [pivotx = 0, pivoty = 0]);

Rotates a layer, in degrees. Default is 0 degrees.

• layername: The name of the layer to check.
• rotation: Amount to rotate the layer to, in degrees.
• pivotx/pivoty: Optional. Specify the pivot point to rotate around. Default is top left. Can use Gfx.CENTER, Gfx.TOP, Gfx.BOTTOM, Gfx.LEFT and Gfx.RIGHT constants here.

Example:

import haxegon.*;

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

    //Set the rotation of the "foreground" layer to 45 degrees.
    //Pivot around the centre.
    Layer.rotate("foreground", 45, 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 LEFT and RIGHT to change the rotation of the "foreground" layer
    var currentrotation:Float = Layer.getrotation("foreground");
      
    if (Input.pressed(Key.LEFT)){
      Layer.rotate("foreground", currentrotation - 2, Gfx.CENTER, Gfx.CENTER);
    }else if (Input.pressed(Key.RIGHT)){
      Layer.rotate("foreground", currentrotation + 2, Gfx.CENTER, Gfx.CENTER);
    }
  }
}
