SceneViewGetAllHitObjects(ListRayHitTestResult, Single, Single, Boolean, HitTestOptions) Method

public void GetAllHitObjects(
	List<RayHitTestResult> allHitResults,
	float x,
	float y,
	bool adjustForDpiScale = true,
	HitTestOptions? customHitTestOptions = null
)

Parameters

allHitResults  ListRayHitTestResult

List of RayHitTestResult items to which the hit results are added

x  Single

x position in this view (for example, a mouse x position)

y  Single

y position in this view (for example, a mouse y position)

adjustForDpiScale  Boolean  (Optional)

when true (by default) the x and y positions are multiplied by the DpiScaleX and DpiScaleY. This should be used when x and y are get from mouse location on the SceneView object. When x any y are from the SceneView.Width and SceneView.Height, then this parameter needs to be false.

customHitTestOptions  HitTestOptions  (Optional)

Optional HitTestOptions that will be used for this hit test. When null (by default), then DefaultHitTestOptions from Scene will be used.

GetAllHitObjects method executes a hit testing from the specified x and y positions on the SceneNodes that are shown by this SceneView and adds the hit objects to the specified allHitResults (as List{RayHitTestResult}). Hit objects are added in order from the closest to the farthest object.

This method first creates a ray by calling GetRayFromCamera(Single, Single, Boolean) method and then calls the GetAllHitObjects(ListRayHitTestResult, Ray, SceneNode, HitTestOptions) method.

To control advanced hit-testing options set the customHitTestOptions parameter (HitTestOptions) or change the Scene.DefaultHitTestOptions that is used when customHitTestOptions parameter is not set (null by default).

To get only the closest hit result, use the GetClosestHitObject(Single, Single, Boolean, HitTestOptions) or GetClosestHitObject(Ray, HitTestOptions) methods.
