Everybody has to start somewhere and if you had to write code that was perfect none of us would be developing mobile games. Or any other kind of software, for that matter. 🙂
Fortunately, the most important thing is to WRITE SOME CODE and worry about making it perfect later. And while I won’t claim the code in this Corona SDK tutorial is perfect, it is a better way to handle displaying multiple objects (of the same type) on the screen at once.
What do I mean? Here’s an example of displaying 4 stars on the screen (not real code, of course):
|
1 2 3 4 5 6 7 |
Create and Display First Star Create and Display Second Star Create and Display Third Star Create and Display Fourth Star |
While that may get the job done, it’s a very inefficient way to handle things. And, if you want 10 stars, or 50 stars, your code is going to get very long (and you’ll be bored to death writing it).
This video tutorial will show you a great way to handle this task. And as a bonus, members of GDN will be able to see a follow-up video that takes the tutorial code to the next level. (If you’re not a GDN member, it’s free to join.)

Very nice tutorial. Thanks.
Really very helpful to beginners like me. I was working on my concept where i had to spawn random boxes with physics…. and so on… and i came across this post and yupeeeee helped me a lot..
Thanks a lot for the small simple Tute.
nice tutorial.thank you so much
got a question to you.i suddenly changed the properties of particular main.lua to be opened with another app(in my case i changed it to corona simulator) and now every time i try to double click main.lua on CPM, it opens the corona simulator. now i’m stuck with it and dont know how to change it back to default way. could you please help me how to do it so everytime i double-click it, it will directly open the editor inside the CPM and make the code editable.thanks
Sounds like Prefs got changed to open the file in an external editor. Open Preferences and under General there’s an option to edit files in CPM or an external editor. Make sure that’s set correctly and try again.
thanks a lot..it works for me now! you rock!
Hi why can’t I view part 2 of this video. It’s telling me to log in and I am but can’t view part 2 ?
I loved out and back in again and still no luck. (I signed up today as well Does that have any thing to do with it ?)
Thanks
Excellent tutorial. Mandatory for all new coders out there, as this saves many lines of code and future maintenance hours, not to mention re-usability.
P.S. The homage to Carl Sagan does not escape me 😉
I also have the same problem as malik, wtf GDN?
In every case I can remember the problem is a matter of not clicking the link in the verification email that was sent out. You sign up, but then an email is sent to you and you have to click the link in that email. It’s possible the verification email was accidentally routed to your junk/spam folder.
Check that and if it’s not there (not sure why it sometimes gets misrouted) I can manually verify you. Let me know.
