hitTest method

  1. @override
GDisplayObject? hitTest(
  1. GPoint localPoint, [
  2. bool useShape = false
])
inherited

Determines if the point specified by localPoint is contained within this GSprite. If useShape is true, the shape of the GSprite will be used to test for containment. Otherwise, the bounds of the GSprite will be used.

The localPoint parameter is a GPoint object representing the point to test for containment, in the local coordinate space of this GSprite.

The useShape parameter is an optional boolean value that determines whether to use the shape of the GSprite or the bounds of the GSprite to test for containment. If it is not specified, it will default to false.

Returns the GDisplayObject that contains the point, or null if the point is not contained within this GSprite.

Implementation

@override
GDisplayObject? hitTest(GPoint localPoint, [bool useShape = false]) {
  if (!visible || !mouseEnabled) {
    return null;
  }
  var target = super.hitTest(localPoint);
  target ??=
      (_graphics?.hitTest(localPoint, useShape) ?? false) ? this : null;
  return target;
}
