I sure hope I inserted the code the proper way. If not, I deeply apologize.
I have that wonderful Meteor Rain running and I have added a return trip so it goes out and back.
The meteor goes out and allows the background color(red) to fully fill in before the green meteor starts its return trip.
But when it gets back the red(background) doesn't fully fill in. I have played with various delays but can't quite get it cleaned up.
Much of the programming is a step above my knowledge so any help would be great.

Poop, I didn't insert the code correctly. Nevertheless please help.

Fixed

Do you mean the fact that it won't compile?

4

No, it seems I didn't insert the code into the post correctly.

5

You posted your code ok, but the problem is your comments/request has become part of the code. I didn't see it at first, until I happened to scroll down to the bottom of the code and saw the extra text. The problem is you need a new line after the 3 apostrophes that mark the end of the code, before your comments/request.

6

Should I create a new post, or reply to this post with proper insertion, or do nothing and wait for help.

(The commented out lines in my code are just my getting ready for a different color meteor and rain pattern.)

7

No, just edit your post and fix it!

8

My code compiles and runs about 95% of the way I expect.

9

I already said in post #3 that it will not compile. I even showed you the reason why.

10

Thanks for fixing your post, I can comfortably read your comments/request after the code now.

11

The code does compile and runs nicely, all except for the meteor coming back and the red not fully filling in.

12

Ok, now I'm calling you out as a liar. Do you think I can't read? Good luck with your project. I'm out.

13

I figured it out.
In the second instance of this command, when the meteor is coming back, I had to change i>=0 to i>=0-30. I guess this allows the meteor tail to run off the led strip.

for(int i = NUM_LEDS+NUM_LEDS; i >=0-30; i--)
