  • Hi Colin,

    Have you tried using Behavior script? You can set the trigger type to "Marker Tracking Event" and set the Marker Tracking component you want to respond to. Then you can set the delay time to cause something to happen that long after the marker is found. See more about Behavior script here: https://lensstudio.snapchat.com/guides/scripting/helper-scripts/behavior/

    If you need more advanced behavior, you can write your own script that causes things to happen after a delay. Here's a really simple example:

    //@input Component.MarkerTrackingComponent m1

    script.m1.onMarkerFound = function() {
        // This will happen right away
        print("Marker Found");

        delayedCall(function() {
            // This will happen after 2 seconds
            print("2 seconds since marker found");
        }, 2.0);

        delayedCall(function() {
            // This will happen after 5 seconds
            print("5 seconds since marker found");
        }, 5.0);
    }

    function delayedCall(func, delay) {
        var evt = script.createEvent("DelayedCallbackEvent");
        evt.bind(func);
        evt.reset(delay);
        return evt;
    }

    And you can do the same thing for a second marker tracker too. Just keep in mind that if the marker is lost you might want to cancel all the pending delayed events. You can track them in a list and remove each one with script.removeEvent() when the object is lost if you run into this.

    Let me know if you need more help!
