Object not falling

Question

I created a space where there is gravity and two objects:

var napeWorld:Space=new Space(new Vec2(0,500));
var ground:FlxNapeSprite = addBox(320, 480, 640, 20, BodyType.STATIC, FlxColor.BLUE);
var hero=addBox(320,60,20,20,BodyType.DYNAMIC, FlxColor.RED);

Here is my addBox() function:

private function addBox(x:Float, y:Float, w:Float, h:Float,bodyType:BodyType, color:Int):FlxNapeSprite {
    var sprite:FlxNapeSprite = new FlxNapeSprite(x, y);
    sprite.makeGraphic(Math.ceil(w), Math.ceil(h), color);
    sprite.body.type = bodyType;
    sprite.body.space = napeWorld;
    //sprite.createRectangularBody(w, h, bodyType);
    sprite.setBodyMaterial();
    add(sprite);
    return sprite;
}

I call step in my update() method:

override public function update():Void
{
    super.update();
    napeWorld.step(1/30);
}

I don't understand why my dynamic shape doesn't fall on the ground...

Any idea?

Answer 1

because you are setting it to be a static body with BodyType.STATIC.

You need BodyType.DYNAMIC to make things move by themselves.
