Not defined?

I was making a game and I left for about an hour. upon returning, I found the error "Warning: camera is not defined, will be initialized to an empty object, in file "main" at line 66, column 12" even though it is defined. I tried refreshing and rerunning but nothing seemed to work

Here's the link

Thanks

I found a few typos in your code.

Here's some of the prominent I have noticed:

• Inconsistent Intendation
• elsif mistyped as else if
• end statements seemingly placed with no sense
• No spacing and no comments

And please, take commenting seriously. It is being pointed out for a reason. After all, you still want to read your code if you come back to it in a couple of weeks or months. The else ifs and the misplacements of the end keyword have caused microstudio to misinterpret your code, giving the error.

Below I have posted the fixed code of the main file. And please, keep your intendation more consistent. It can avoid confusion and beginner mistakes.

Thanks! I'm new to Lua and I usually code in python so this is all new for me.
