Alpha Video Plays Early

[keith_pace]

Right now the alpha video is starting as soon as the experience finishes loading. I need it to start once the trainer image is triggered. Any help? I am not much of a coder.
Here is a snapshot of the show code:
const display_shown = symbol.controllers.display.elements.shown;
const display_hidden = symbol.controllers.display.elements.hidden;
var Zappar_1_mp4 = symbol.nodes.Zappar_1_mp4;

parent.on(“show”, parent_show);
function parent_show() {

// Make sure we start from fully hidden
display_hidden.reset();

// Move to the shown state
display_shown.activate();

// Start the video

Zappar_1_mp4.start();

}

Hallo, you should use a -seen- script for the target… it’s easy… click on the target and find new script> Seen

I appreciate the response. Any chance I could get more detail? Sorry - newbie here.

Also, how do I get the video to stop auto play once the experience loads?

I got a response from Zappar support that helped. See below:

The reason your video starts playing as soon at the experience is loading is because your .start() code is in the ’show’ script/function. This means that whenever the experience is shown, we will carry out these specific behaviours.

To play the video when the target is seen, you can create a separate script. Simply right click on your target image and then left click on New > Script > Seen. This will create a new script for when your target image is seen (I’ve attached a diagram of this to the email). You can then write your behaviour in this new script.

Hi everyone!

This resource may also be helpful when it comes to ‘On Seen’ and ‘On Not Seen’ events: https://docs.zap.works/studio/getting-started/image-tracking/#target-events

Have a great day!
