Scenes

In the precedent sections we already used s2d which represents the active current scene rendered by the hxd.App.

A Scene (represented by h2d.Scene) represents any scene the user can visit in the Heaps app. Scenes may be an intro showing the developers logo on start-up, the main menu of the game, maybe a cutscene and finally the level or world where the actual game takes place and the player walks around.

h2d.Scene (represented by h2d.Scene) is a special object (it is actually a h2d.Object, too!) which is at the root of the scene tree. In hxd.App it is accessible by using the s2d variable (as we have seen previously). You will need to add your objects to the scene before they can be displayed. The Scene also handles events such as clicks, touch, and keyboard keys.

class Myapp extends hxd.App
{
    override private function init():Void
    {
        super.init();
        s2d;                            // the current scene
        var myscene = new h2d.Scene();  // create a new scene
        setScene(myscene);              // set it as the current scene
        s2d;                            // is now newscene

        var myobj2 = new h2d.Object();
        s2d.addChild(myobj2);

        var myobj = new h2d.Object(s2d);// add myobj to s2d by passing s2d as parameter

    }
}
