The idea is depends on if you want to use garbage collection in javascript or not. You can leave them and let javascript to handle this deletion or you want delete them explicitly by using xxx.destroy()

And how about your array, if it’s a property in QML or not

Thanks for your reply Chuck. I have another question. How would I limit the number of falling objects in my game? Since I still haven’t implemented a timer.. I want to have falling objects stop, say, after one minute? how’s that?

1. Just use a int property like

2. I think timer is the best way, it’s very simple using QML :D

Dynamic Object Management in QML :

but hey how can I destroy an object based on an event or on a trigger??
for example.. if the user inputted/key in a correct answer the falling object must be destroyed?
how would i do that??

I had done similar coding for my The Math Game, in this game some coulds fall from top and when user answer correct answer it got destroyed.

I had written down my experience for creating that game in following post. Check out “Performing animation on component destruction.” section. that might help you.
