A Training can mark some objects as **pause colliders**, for example a hot surface, moving machinery or a hazard you must not touch. If you touch a pause collider, the Training pauses and warns you. ## What Pauses the Training The Training pauses when any of these touch or enter a pause collider: * Your **hand** or **controller** * Your **head**, for example if you lean into the area * A **tool** you're holding * A training object you're **carrying** Pointing the ray at a pause collider and pressing select also pauses the Training. ## When the Training Pauses * A red tint appears around the edges of your view, and an error sound plays. * A message card explains the hazard. If the Training doesn't give its own message, you see **"You have entered restricted area."** * **Next** is hidden and **Back** can't be pressed. You can't interact with training objects, and any step video pauses. If the pause was caused by a training object you're carrying, you can still interact with training objects. A pause collider message card reading DO NOT TOUCH in front of an engine, with a red tint around the view ## Continuing the Training There's no button to press. **Move your hand, controller, head or tool away** from the pause collider, or release select if you were pointing at it. The Training carries on from where you were. If you're carrying a training object, moving just the object out isn't enough. Move the hand or controller that holds it away from the pause collider. The red tint clears as soon as you move away. The message card closes once you've moved away and it has been up for at least 3 seconds. If the Training pauses and you're not sure why, look at the message card. It usually names what you touched. *** ## For Creators To add pause colliders to a Training, see [Pause Training](/creator-studio/creator-app/actions/pause-training).
