This example will show you how you can use the Hotspot Play or Hotspot Paused Event.
In this example a corner shelf will appear when the player presses the Play button, and disappear when the player presses the Pause button.
In ECA you will use the Event block, where you choose Hotspot Play Pressed and then choose the hotspot from which the Event is to be performed.
Then choose the Action block and select which Action to perform when the Event occurs. In this example as mentioned the corner shelf will appear when the Play button is pressed, and disappear when the Pause button is pressed. To specify whether the corner shelf should be visible or invisible, the objects metadata Active is set to 1 for visible and 0 for invisible.
he top you can see how this specific example of an ECA Event would appear in VR.
