how to detect if img didnt clicked in sertain time

Hi!

I recommend you to take a look at the User Interface section: https://lensstudio.snapchat.com/guides/scripting/helper-scripts/user-interface/ and at the "Adding behaviors to your widgets" specifically. 

The solution could be like following: you would need two buttons. Click on the first button will show the second button, and click on the second button will determine if game is won or lost. If the second button was clicked before 1 second passed, game is won, otherwise game is lost. 

Please, take a look at the attached project. In there you can find UI Rounded Button with the UI Button script on it which runs a function of the Shower script also attached to this object. That script  enables the second button.

//@input SceneObject obj
script.api.show = function () {
    if (script.obj.enabled)
        return;
    script.api.clickTime = getTime();
    script.obj.enabled = true;
}

You can also find the Image object (which itself is also a button) and disables itself when clicked.

The last piece of this setup is GameOver controller, that counts how much time passed since the first button was clicked, and if it is greater than 1 second it prints "Game Over!".

Please take a loot at the attached project

Hope this helps.
