Debugging
This page describes the tooling that you can use to debug virtual experiences, from the creation process to the virtual experience itself.
Debugging the Tool
The Scene built in unreal can be debugged through the editor utilities built into blueprints.
Debugging using BP_Hotspot
With the utilization of bp hotspots, it becomes possible to track the floor position of the pano. To access this functionality, you need to choose the BP_hotspot blueprint within the editor. Then, under the default options tab, simply click on the "Get hotspot floor position" button. This action will demonstrate a ray trace from the hotspot to its corresponding floor position.
Furthermore, it is possible to monitor the visibility of other hotspots from a chosen hotspot. To make use of this functionality, select the BP_hotspot blueprint in the editor and navigate to the default options tab. There, you will find the "Trace visible hotspots" button. Clicking on this button will initiate a raytrace from the hotspot, revealing the floor positions of all hotspots that are currently visible. Additionally, if the hotspots are visible, the line traces will be shown in green. Conversely, if they are not visible, the line traces will be displayed in red.
Likewise, we have the capability to track all visible interactables from a hotspot. To access this functionality, choose the BP_hotspot blueprint in the editor and then go to the default options tab. There, you will find the "Trace visible interactables" button. When you click on this button, a raytrace will be initiated from the hotspot to all visible interactables. If the visibility is obstructed, the green trace will stop at the collision point, and then the red line will continue from there, indicating the path of the raytrace.
Debugging using Interactable Component
The collision corners of a mesh with the Interactable component attached can be easily visualized. To do this, select the Interactable component and go to the corners tab. From there, click on the "Show corner" option, and this will draw the outline of the four collision corners on the front face, along with one at the center of the front face.
Debugging the Experience
The virtual experience can be debugged through the console, and with additional query parameters.
Query Parameters
You can add specific query parameters to debug the experience. Adding ?debug=true to the URL of the experience, will show you the debug elements, clickable areas and other important information about the experience.
Console
The console provides useful information about the experience and problems that arise. At the moment, only Emperia team members can act upon these errors.
