We’ll be performing two types of Raycast. Once we have the current touch and the touchCount meaning the number of fingers, on the screen is just 1, we can perform our Raycast.

And we check for touches every frame, we do it inside the Update method. Since we want to check for touches on the screen. public ARRaycastManager arRaycastManager So we create two public fields and will assign them from the Inspector. We need references to the ARRaycastManager component and the cube prefab. You can move this into a new folder called Scripts for better project structure management.ĭouble click on the CubeManager script and it should open up with Visual Studio. Unity will now create a new script called CubeManager.cs in the projects root folder – Assets. Add Component on the gameobjects Inspector -> type in CubeManager -> New script -> Create and Add. To this gameobject, we’ll create and add a new c# script. We’ll create a new gameobject by right click in the Hierarchy > Create Empty -> Rename it to CubeManager. Next, Let’s set up our CubeManager class. You can now delete the Cube gameobject from the Hierarchy.
Now, to make a prefab out of this Cube gameobject, drag it and drop it on the Prefabs folder in the Project window. Select the “cube” tag in the Cube gameobjects Inspector. Unity will open the Tags and Layers page in the Inspector Window.Įnter the name as “cube” (smalls) and save. Select that and select the Add Tag on the bottom of the shown list of tags. Once the cube is selected, In the Inspector window there is a Tag property on the top left. Unity will have a few default tags, but we want to create a new one and assign it to the cube gameobject first. When we Raycast against the cube, we can then compare the tag and find out if it’s a cube that we tapped on. Since we want to delete a cube when we tap on the cube, we want to be able to identify uniquely that it is our cube prefab, we can do this in a number of ways, but the simple and effective method is to tag our Cube prefab with a string. This will create a new Cube gameobject in the scene. Right-click in the Hierarchy -> 3D object -> Cube. Implementationįirst, Let’s create our Cube prefab. If we tap on the cube again, we delete the cube. When a plane is identified by the ray, we will fetch the position of where the ray hits the plane and create our new Cube gameobject from a prefab there.
We will have a CubeManager class that will detect the touches on the screen and Raycast against the detected planes in the scene.
We’ll leverage this class as it provides just what we require for this project. However, AR Foundation provides its own Raycasting method called AR Raycast Manager which we have already set up before. If the Ray hits any collider or a physics object like a Rigidbody, we can fetch information about the Hit object. Raycasting is creating an imaginary line originating at a point with a specific direction. We talked about raycasting more in the Plane Area Calculation tutorial from here. We’ll be using Raycasting to identify and select the desired planes.
