Hihi, I made this because its just sorta cool and might shorten some codes.

Spoiler: Code

Code (Text):

1. expression nice boolean of [boolean] %boolean%:
2.     get:
3.         if expr-1 is true:
4.             return "&aTrue"
5.         else:
6.             return "&cFalse"

Spoiler: Usage

Code (Text):

1.  
2. command /fly:
3.     permission: donor.rank
4.     permission message: &cGet denied FOOL
5.     trigger:
6.         if player's flight mode is true:
7.             set player's flight mode to false
8.         else:
9.             set player's flight mode to true
10.         send "Flight enabled: %nice boolean of boolean player's flight mode%"

Thanks, its short but I guess its pretty useful & simple.
