Nodes for working with variables — the named values your scene keeps and reuses, each holding a number, a piece of text, or a time. Cast Variable Checks whether a variable holds the kind of value you expect, and only passes it along when it does. What it ...

These events fire when a user picks up or lets go of a scene object in VR. Use them to react the moment an object is grabbed or released — for example to highlight a tool when it is held, or reset it when it is put down. Each event also tells you which user ...

These events fire when a user points at or moves away from a scene object in VR (without grabbing it). Use them to react as an object is hovered — for example to highlight it, show a label, or hide that hint again when the user looks elsewhere. Each event also...

These events fire in response to what a playing sequence does, so you can react automatically when a sequence reaches a key moment — without having to start the check yourself. Sequence events Sequence Ended This node lets your scene react the moment a s...

These events watch a true/false value and fire the moment it changes — so you can start something the instant a condition becomes true, becomes false, or simply flips either way. They never change the value they are watching; they only react to it. Boolean ...

The Dynamic Cloud Attribute nodes save and read small pieces of text in SimLab’s cloud, so a VR experience can remember information between sessions and across devices — a person’s progress, a saved choice, a score, and so on. They are the flexible counterp...

The VR Assembly System in SimLab Composer provides an intuitive, code-free framework to design step-by-step 3D disassembly and reassembly procedures for Virtual Reality and interactive 3D desktop environments. By using a visual node graph, you can map out exac...

Complex mechanical equipment often requires more than simple individual part removal. SimLab Composer allows you to group components into sub-assemblies and create custom components controlled through the Training Builder to handle specialized tools like beari...

When building mechanical assembly diagrams in SimLab Composer, different components require different rules for when they can be detached. Dependency Modes dictate whether a part requires all preceding connected components to be removed first or if removing an...

The Web Browser VR node shows a web page on a plane in the VR viewers. When you set its Source to HTML, you type the page in Composer, and the viewers load that text as the page. The viewers add a set of JavaScript functions to the page's window. A page from S...

A quiz is a set of questions you build with the VR Quiz tool in SimLab Composer — multiple-choice, object-picking or star-rating questions, with an optional time limit. The node on this page shows a quiz to the trainee during the experience. To react to what t...

These events fire while a trainee works through a quiz that was shown with Activate Quiz. Unlike most nodes they have no Execute input — they fire on their own when something happens in the quiz, and hand you details such as the question, the trainee’s answers...

The nodes on this page send results from a running experience to the web dashboard of the scene’s Dashboard Project, where trainers and managers review them. You can report a value (such as a score or a time), report a file (such as a screenshot), or ask the t...

These nodes help you check how smoothly an experience runs on a device. Get FPS reads the current frame rate, and Record FPS To CSV saves a reading to a spreadsheet file or sends it to a server, so you can compare devices or find heavy moments in a scene. Wha...

These nodes take pictures during an experience. Capture Picture shows a camera’s view on an object in the scene, while Take Screenshot to file and Capture Camera to File save a PNG image file that you can then report to a dashboard or upload to SimLab Cloud. ...

On mixed-reality headsets, an XR anchor pins a virtual object to a spot in the real room, so it stays put as the user walks around — and appears in the same place the next time the scene starts on that headset. These nodes anchor an object where it currently i...
