How do I set a variable to be 100 LESS than it's original value? I tried... --- Code: --- $rackunit = $rackunit - 100 --- End code --- and --- Code: --- $rackunit = {$rackunit - 100} --- End code --- and --- Code: --- $rackunit - 100 --- End code --- but nothing seems to work what do |
| Treynolds416:
Many ways to do it --- Code: ---%var = %var - 100; %var -= 100; %var += -100; --- End code --- etc. Anyway be careful, you haven't used a semicolon in any of your examples. You may want to look at a scripting tutorial about basics, you seem pretty uninformed about scripting syntax in general. |

$rackunit -= 100; the first one would have worked if you remembered a semicolon, but you can set a variable with maths (what a horrible way to explain it, haha) by just doing op= instead of =. ie +=, -=, *=, /= Warning - while you were typing a new reply has been posted. You may wish to review your post. welp |

i think the second one would've worked too with a semicolon in java {} are used by for/while/if and other statements, but can also stand alone, so i'd assume it'd not affect anything here either |
