Bug: if you have two overlapping objects and click on the overlapping part the topmost object is not picked as expected. I'm using "on object clicked" and a family. If you instead use it specifically on each family member it works fine.
It looks like an old bug since I've found several posts about it in the forum.
It's the same in every broser I've tested: IE, Firefox, Chrome, Opera.
Here's a capx of the problem
Edit: solution/my bad:
I've totally missed this feature, it works adding extra condition "pick top instance".
Develop games in your browser. Powerful, performant & highly capable.
This isn't actually a bug - when you click the intersection of the two objects, 'On Numbers clicked' runs with both instances picked. When you get an expression with two instances picked, it arbitrarily picks the first instance (which in this case is 'One').
To fix it, just add a 'Pick topmost' condition after.
Edit: solved before me :)
