I'm a 16 year old high school student, I like to create and maintain many extensions. I research a lot daily to bring something new to App Inventor :smiley:
While my primary goal and perspective on App Inventor is not to earn money, it really helps and motivates me a lot if you could spare some donations. :hugs:

Yes, the number of rectangles formed or the number or places where motion was detected
BTW did you flag the above post?

Renaming these events as suggested below would be good practice.

OnMotionDetected → MotionDetected
OnCameraError → CameraError

(Offtopic)When you take a look at most of the native components and many extensions how they are named :joy: . How often you will find this „when after“ thing? but I agree with you.
