![]() ![]() Initially uses estimated depth provided by the app. Place an object on an arbitrary surface (not just on floors and walls)ĪRRaycastManager.Raycast(Vector2 screenPoint, List hitResults, TrackableType trackableTypes TrackableType.FeaturePoint) Relies on visual features around the point of a user tap to determine a point’s correct position and orientation Fallback for the Depth hit-testĪRRaycastManager.Raycast(Vector2 screenPoint, List hitResults, TrackableType trackableTypes TrackableType.PlaneWithinPolygon) Place an object on a plane (floor or wall) using the plane’s full geometry. Hits horizontal and/or vertical surfaces to determine a point’s correct depth and orientation Place a virtual object on an arbitrary surface (not just on floors and walls)ĪRRaycastManager.Raycast(Vector2 screenPoint, List hitResults, TrackableType trackableTypes TrackableType.Depth) Uses depth information from the entire scene to determine a point’s correct depth and orientation Hit result typesĪ hit-test can yield four different types of hit results, as shown by the following table. Correct placement ensures that the AR content is rendered at the appropriate (apparent) size. I think the fact that it's on a layer in the first place might be breaking things because it looks like the default it for a Graphic Caster is to be blocked by "Everything" which I'm guessing your BGCanvas has it's blocking mask set to.Perform a raycast, or hit-test, to determine the correct placement of a 3D object in your scene. ![]() ![]() Try setting the Overla圜anvas to not be on a layer. This is pretty much the same way that PointerInputModule does raycasting with EventSystem.RaycastAll in Unity (except with more caching). Results will now contain all of your hit canvas objects. Set required parameters, in this case, mouse position PointerEventData ped = new PointerEventData(null) Create the PointerEventData with null for the EventSystem GraphicRaycaster gr = this.GetComponent() Code to be place in a MonoBehaviour with a GraphicRaycaster component For this we need the following snippet of code where we create a PointerEventData object to send to the Raycast function. ![]() You can also use it directly by calling the GraphicRaycasters Raycast function itself instead of creating code as a response to an event. This video shows the specific implementations of each method.įor more on the event system, triggers, and how they all work together this video might help as well. These are the .Handler interfaces like the IBeginDragHandler interface If you would like to avoid the editor, your MonoBehaviour can implement a given interface depending on the event your want to capture.Use event triggers (found in Component > Event > Event Trigger and use the editor to create all your connections.From here you have a few methods of capturing the event and using it to your will. If your bitmask was 0000000000000101 represented as (1 | 1 UI > Event System. The bitmask is coded so each bit represents a layer. You're interested as to whether it hit an object and what that object was.īlocking objects would be the objects that you specifically define your raycast to be able to hit.Ī blocking mask allows you to, instead of passing tons of blocking objects, define the layers in Unity you want your raycast to be able to hit in the form of a bitmask. It's like if you threw a rock and it continued on in that direction forever, it wouldn't stop until it hit something. With a raycast you're casting a ray, cast being used like the word throw. What is a raycast? What are blocking objects and blocking mask?Ī ray is a mathematical device that starts at an origin point and continues on in a specific direction forever. ![]()
