hi,
condition 1 on clicked button
condition 2 video is not visible/on screen or some secondary condition that tells the button to not do the action while video is playing.
or you can move the button out of the screen with a toggle
condition 1 on clicked button
play video
set button x to button.x=512 ?-200:512
assuming the 512 is the original position of the button on screen if it's 120 or whatever the X position of button is just replace the 512 with that value.
-200 is outside value i just picked you can make it anything.
to make it come back lets say you stop the video or have a X button on video, then u do the same action on X pressed set button x to button.x=512 ?-200:512
