Chapter 5 - asteroids disappeared, at the step right before Hiding the Scene

Getting Started Newbie Questions
#1

Hi all,

I need help to my code, please.

I am very new to coding, so I followed Getting Started chapter by chapter. Everything went well until I finished at Chapter 5, Phases and Transitions. Please roll up a little bit from Hiding the Scene, there is a light purple box with “Action!” title. I was at it yesterday. When I ran the simulator, everything went well except the asteroids disappeared entirely! :wacko:

However, according to what the Action purple box mentioned, the game scene should be identically the same though.

Of course the ship won’t die without asteroids, I have no clue if the text update will be correct. There was no Error message either. I tried comparing 3 lua files with chapter’s source files manually, line by line, fixed a few typo, rerun, closed everything and ran again. The asteroids still not show up. I attached my StarExplorer folder as a zip with this post, or you can download it from my google drive.

I renamed the folder name from [StartExplorer] to [StarExplorer_by Olina] just for asking question. In case you think the folder name with the blank is the issue. No, I don’t do it on my computer. The file names main.lua, menu.lua and game.lua with “_from offical”  are the downloaded chapter’s source files.

(I put them in the same folder so that I can compare.) main_original.lua is the file when Chapter 3 finished.

I noticed that I have to compare both code manually. Because earlier I think I should try typing by myself, I didn’t leave the exactly same space as the tutorial showing. I use Visual Studio Code as my editor, and I use compare function in Notepad++, but it will show differences if I don’t have the same space. Is any solution for this?

Finally, I compare them in VS code with split window, I tried to match the code line number to the official one as much as possible. I hope all these help helpers’ work.

Thank you in advance.

Hi all,

After I post this question, I kept bothering around friends with this question. Otherwise I cannot proceed. A developer friend, ex-coworker, found the issue for me.

I typo gameLoop as gameloop, so the game loop doesn’t run.

It should be:

gameLoopTimer = timer.performWithDelay( 500, gameLoop, 0 )

What I was wrong:

gameLoopTimer = timer.performWithDelay( 500, gameloop, 0 )

As for this post, since I answered my question by myself, I am not sure if I should delete this post to keep the forum clean, or keep it for a future reference? I guess I will leave this decision to Corona official staff to decide.

Thank you!
