# Sequence --- ### Attach Sequence To [Creating sequences](https://simlab-soft.com/help/books/simlab-composer-help/page/sequence-timeline) can be done from animating an object in the scene. This sequence can be attached to Hand or an Object in VR. #### Hand With sequences available in the Sequences Library, a sequence can be attached to the Hand in VR experience using this node in Dynamic Training Builder. #### Example Check this [tutorial ](https://www.youtube.com/watch?v=YkPAQTO5GKE)for the example below, where Boolean expressions were created and upon checking the Boolean Expression a sequence is attached to Hand.

In this example a simple grabbable sequence can do the job, but this is just to demonstrate use of this node.

Here on "**Scene Start**","**Play Sequence**" response is executed for "Elevator\_Up" sequence. Followed by a 1 second "**Delay**", then "**Stop Sequence**" for another one second "**Delay**". Then the sequence is continued, followed by another "**Delay**" then "**Resume Animation Sequence**" from start.

The reverse control will start from the last frame not from the current (because it reverses the overall animation) In the below example the "Elevator\_Up" sequence upon clicking "Elevator\_panel(2)" geometry will be played from start. So if the elevator at that time was at the top position, it would go down then -as the sequence implies- would go up, then wait for 5 seconds, then "Reverse Sequence" that is go down from last frame.

[![image.png](https://simlab-soft.com/help/uploads/images/gallery/2025-10/scaled-1680-/QSBimage.png)](https://simlab-soft.com/help/uploads/images/gallery/2025-10/QSBimage.png) #### Flip Flip sequences flips current animation (that is, forward animation will be backward , backward animation will be forward). Think about it like we are opening a door and we pause the animation in the middle, flip control will return the door back from the current frame to original start position. #### Stop Stopes the animation sequence, as shown in examples presented in this section. --- ### Playback Properties #### Current Frame ##### Get Sequence Current Frame This node will get the value of the current sequence frame, the user can then use this value in any operation. In the example below the value of the current sequence frame is stored in "Current\_Frame" variable, which is set to the "VR Variable Writer" in the scene to display its value. [![image.png](https://simlab-soft.com/help/uploads/images/gallery/2025-10/scaled-1680-/0ESimage.png)](https://simlab-soft.com/help/uploads/images/gallery/2025-10/0ESimage.png) [![image.png](https://simlab-soft.com/help/uploads/images/gallery/2025-10/scaled-1680-/eqmimage.png)](https://simlab-soft.com/help/uploads/images/gallery/2025-10/eqmimage.png) ##### ##### Set Sequence Current Frame If the user wants to go to a specific frame in the sequence this is the function to use. In the below example upon clicking node the sequence current frame is set to 10. [![image.png](https://simlab-soft.com/help/uploads/images/gallery/2025-10/scaled-1680-/8l6image.png)](https://simlab-soft.com/help/uploads/images/gallery/2025-10/8l6image.png) To show the result we got the valued of the current frame and assign it to "Current\_Frame" variable that is displayed in the variable writer as shown below.
