Troubleshooting

Tab 3 lists problems

Tab 3 Generate lists everything that would stop the lesson from working, with the step number. The most common ones:

Problem	Fix
Step … waits for a flat button, but none is chosen	Pick the button in the step's Button list, or choose another Trigger Method.
Step … waits for a hand-pressable button, but none is chosen	The same, for push buttons.
Step … puts its destination on an object, but no object is chosen	Drag an object into the step's Attachment Target under Completion Trigger.
Step … attaches its canvas to an object, but no object is chosen	Drag an object into Attachment Target under Guidance & UI, or choose another Placement Mode.
Step … shows a video, but no video link is set	Paste a YouTube link into YouTube URL.
Step … shows an image, but none is chosen	Drag a picture into Source Image.
Step … has no text	Type the instructions into Text Content (Editable).

My button isn't in the Button list

• It wasn't placed with Button Injection. Only buttons placed with Button Injection are listed.
• The wrong trigger method is chosen. Flat buttons are listed under Press a flat button, push buttons under Press a hand-pressable button.

The learner can't move on

• The step waits for something else. Check its Trigger Method. Only Press Next on the guidance canvas uses the Next button.
• A flat button doesn't react. The scene needs an Event System. See Button Injection: Troubleshooting.
• The place to reach is too small or out of reach. Make the Radius (Meters) bigger, or move the zone with Preview & Adjust Zone.

My changes don't appear in the scene

Changes in tabs 1 and 2 only reach the scene when you press Update Existing Scenario System in tab 3 Generate. Then save the scene.

The video panel is blank

• No video ID was detected. Copy the link again from YouTube. See Write the instructions for a step.
• The headset is offline. Videos need an internet connection.

The window only shows a warning

The scene is playing. Stop Play mode, and the tool works again.
