Good afternoon, my friend! I have a problem. I need that when I click on any block in the region, the value of the variable changes.

Code (Skript):

1. on rightclick:
2.     loop all blocks in region{Ogorod}:
3. # PROBLEM LINE
4.         if {Proverka} = 0:
5.             set {Proverka} to 1
6.             if {Speed_Attack} = 1:
7.                 subtract {Damagel} from {Heal}
8.                 wait 1 seconds
9.                 set {Proverka} to 0

And also, do not tell what color scheme do you use to highlight the code?
