Math: Modulator (Mod) Operator Problem

[Griffen25]

been awhile since my calculus days;
I'm currently using a real variable as a timer, deducting 0.2 seconds from it at each interval and updating/displaying it in the form of a floating text.

however, I would like it so that each time the real is equal to a whole number (integer) to change the floating text colour to white, instead of red. So it appears to be almost blinking.

This is what I've tried, can somebody help me please!

• Fortify Timer
  • Events
    • Time - Every 0.20 seconds of game time
  • Conditions
  • Actions
    • Game - Display to Player Group - Player 1 (Red) for 0.33 seconds the text: Fortify Timer is on
    • For each (Integer A) from 1 to FO_Max, do (Actions)
      • Loop - Actions
        • -------- - - - - - - - --------
        • -------- - - - - - - - --------
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • FO_Time[(Integer A)] Greater than 0.00
          • Then - Actions
            • -------- - - - - - - - --------
            • -------- - - - - - - - --------
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • Or - Any (Conditions) are true
                  • Conditions
                • (FO_Time[(Integer A)] mod 1.00) Equal to 0.00
              • Then - Actions
                • Game - Display to Player Group - Player 1 (Red) for 0.50 seconds the text: MOD Trigger
                • Floating Text - Change the color of FO_Floating_Text[(Integer A)] to (100.00%, 100.00%, 100.00%) with 0.00% transparency
              • Else - Actions
                • Floating Text - Change the color of FO_Floating_Text[(Integer A)] to (100.00%, 0.00%, 0.00%) with 0.00% transparency
            • -------- - - - - - - - --------
            • -------- - - - - - - - --------
            • Floating Text - Change text of FO_Floating_Text[(Integer A)] to (Substring((String((FO_Time[(Integer A)] - 0.20))), 1, 4)) using font size 11.00
            • Set FO_Time[(Integer A)] = (FO_Time[(Integer A)] - 0.20)
            • -------- - - - - - - - --------
            • -------- - - - - - - - --------
          • Else - Actions
            • Floating Text - Destroy FO_Floating_Text[(Integer A)]

It's getting late and my head is hurting, but I could have sworn that this was right. however worldedit doesnt seem to agree with me =P

• (FO_Time[(Integer A)] mod 1.00) Equal to 0.00

Are you using another trigger to deduct the 0.20 from the real variable? I don't see that anywhere in this trigger.

Also, try displaying the value of the variable, to make sure it's not offset by some value between 0.00 and 0.199.

I'm pretty sure mod only works on integers.

7 mod 3 = 1
4 mod 3 = 1
1 mod 1 = 0
2 mod 1 = 0
X mod 1 = 0

Get it?

If you want to check whether a real number is a round number or not, perhaps you could try this:
Multiply the real by 10 then mod it by 10.
So...
7.2*10 mod 10 = 2
7.0*10 mod 10 = 0

Or perhaps there is a math function that checks for round numbers?

If you could understand JASS and maths you could take a look here http://www.thehelper.net/forums/showthread.php?t=140220

wouldn't something like

CustomScript if R2I(FO_Time[(Integer A)])==FO_Time[(Integer A)] then

work too?

• [...]
  • If - Conditions
    • Or - Any (Conditions) are true
      • Conditions
    • (FO_Time[(Integer A)] mod 1.00) Equal to 0.00
  • Then - Actions

Your problem there is in the condition - you appear to have an extra, unused "Or" there, with nothing in it, which is making the whole condition always false.

I'm pretty sure mod only works on integers.

Nah, it works on reals too.

CustomScript if R2I(FO_Time[(Integer A)])==FO_Time[(Integer A)] then

Yeah, that's another way, which in GUI would be

• Real(Integer(FO_Time[(Integer A)])) Equal to FO_Time[(Integer A)]

strange...

7.2*10 mod 10 = 2
7.0*10 mod 10 = 0

huh. I got a strange result;
(note: 25 is my starting value)

250.000 % 10 = 0.000
248.000 % 10 = 8.000
246.000 % 10 = 6.000
244.000 % 10 = 4.000
242.000 % 10 = 2.000
240.000 % 10 = 10.000
238.000 % 10 = 8.000
236.000 % 10 = 6.000
234.000 % 10 = 4.000
232.000 % 10 = 2.000
230.000 % 10 = 10.000
228.000 % 10 = 8.000
226.000 % 10 = 6.000​

but that is fixable. I'll just make it whenever its equal to 10.000 or 0.000
its a dodgy fix but it should work. I'll let you know how it turns out.

------------------------------------------
EDIT: I Got it :thup:, its a little hard to read and I would not submit it anywhere, but it does work. If I get the time I will try and refine it.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • Or - Any (Conditions) are true
      • Conditions
        • ((FO_Time[(Integer A)] x 10.00) mod 10.00) Equal to 0.00
        • ((FO_Time[(Integer A)] x 10.00) mod 10.00) Equal to 2.00
  • Then - Actions
  • Floating Text - Change the color of FO_Floating_Text[(Integer A)] to (100.00%, 100.00%, 100.00%) with 0.00% transparency
