AR Object Camera Focus

Hi Jordan,

Sorry to hear you're having that issue! This doesn't sound like it could be caused by your lens, is it happening with other lenses too? Do you see it in Snapchat without lenses turned on, or in your phone's standard camera app?

Sorry for all the questions, but it's hard to tell where the problem could be happening. If you'd like to share some information about your phone (iOS/Android, device model) that could help as well.

Thanks,
Jacob

Hey Jordan, thanks for the info and picture! 

Like you mentioned, it's likely caused by the "TouchCollision" object. Since it's used for manipulating the main object, it blocks any taps that touch it from being registered as focusing. So it could be the case that it's too big and is blocking the entire screen.

What you can do is resize the TouchCollision object to better fit the boundaries of your model. The Frame Tool is really helpful for this - you can use the hotkey "T", or look for this icon in the 3D toolbar:

If that doesn't solve your problem, I have one more theory of what could be causing this. On your Device Tracking component, did you switch Tracking Mode to "World", or enable Native AR tracking? ARKit being active can sometimes prevent the phone camera from refocusing, so you can try changing Tracking Mode back to "Surface" and and disabling "Use Native AR" if all else fails.

Hope this solves it! Let me know how it goes, or if you have any other questions about it.

Thanks,
Jacob

Hey Jordan, glad that worked!

You can block touch inputs using Touch Blocking. You just need to enable touch blocking, then add exceptions for all the touch types you still want to allow. To only block zooming, you can use a script like this:

// Enable global touch blocking
global.touchSystem.touchBlocking = true;

// Add exceptions for each touch type you still want to allow
global.touchSystem.enableTouchBlockingException("TouchTypeTap", true);
global.touchSystem.enableTouchBlockingException("TouchTypeDoubleTap", true);
global.touchSystem.enableTouchBlockingException("TouchTypePan", true);
global.touchSystem.enableTouchBlockingException("TouchTypeSwipe", true);

Or, you can do it slightly more compactly too :)

// Enable global touch blocking
global.touchSystem.touchBlocking = true;

// Add exceptions for each touch type you still want to allow
["Tap","DoubleTap","Pan","Swipe"].forEach(function(n) {
    global.touchSystem.enableTouchBlockingException("TouchType"+n, true); 
});
