Use Body Detection to trigger the next node when the camera detects a body interacting with the camera viewport. Body Detection is in the Body category.
|Begin||Trigger||Execute the next node when any part of the body is detected|
|Stay||Trigger||Keep executing the next node when the body stays in the camera viewport|
|End||Trigger||Execute the next node when the body disappeared|
|None||Trigger||Keep executing when nobody is detected|
In this example we use Body Detection to show and hide the alien avatar.
