WS2812b RGB LED Matrix With Scrolling Text using an Arduino

Here's an WS2812B LED Matrix using a bottom left zig zag pattern. it is using the adafruit neomatrix as well as fast LED libraries.
the below code is for the same scrolling effect though uses a more efficient library. there's also bouncing balls in it. there are comments that state what where certain things do certain things

TO USE THIS CODE!!
Be sure to get the following Libraries
Adafruit_gfx
FastLED
FastLED_NeoMatrix

Replace the following characters
(((( Left facing culry bracket
)))) right facing curly bracket
zz)zz) angled bracket pointing right
(zz(zz angled bracket pointing left

[manongdiychannel]

can you pls give me some code for text scrolling. the code here for me is not working. thank you

[voravichs.]

I follow you like a picture that turned out to be a mirror image, how do I fix it?

[backwoodselectronics]

All I get is the bouncing balls but, no text. I went over this sketch several time and everything is correct. How do I fix this problem?
