Hi Saparjumashev
There is a lot of really great Corona courses on the internet.
I would suggest you commit to one of them for a couple of months and most if not all of these types of questions will get answered.
I would suggest this course as it is the most comprehensive course available as far as I am concerned.
It might be subtitled but you can always follow with ease.
Hope this helps
I can not recommend thilima’s tuts cause I haven’t watched them, but for sure go check YT Corona channel, Ludvik Koutny did some great explanation videos back in the days!
thanks guys. sure I’ll be fine
