Comparing angles in GUI

Nenner	Ok so what I want is a trigger that checks the difference between two angles. Angle(a) - Angle(b) does not work since the angles range from 0-360 and then start over at 0. And I don't know JASS yet so try to keep it in GUI.

Troll-Brain	just check which value is the biggest and then do that : max value - min value Depends what you want exactly In this exemple the difference beetween the twice angles is 90 or 270 °

Nenner	What I need is a trigger that only runs if the difference between the two angles is <40 degrees. The problem occurs when one of the angles is 320-360 or 0-40 degrees.

Troll-Brain	if the difference > 180 then add 180 to the result. if the difference < 0 then add 180 to the result

I'm sorry but that makes no sense.

botanic	goto file options and enable negative numbers then get the absolute value of the A1 - A2 It would look like this in GUI: abs((A1-A2))

Troll-Brain	Trigger: test Events Player - Player 1 (Red) types a chat message containing test Conditions Actions Set Real1 = 10.00 Set Real2 = 350.00 Set Real = (Abs((Real1 - Real2))) If (All Conditions are True) then do (Then Actions) else do (Else Actions) Si - Conditions Real > 180.00 Alors - Actions Set Real = (Abs((Real - 360.00))) Sinon - Actions

botanic	my method would take lead function calls which would be more optimized code. One abs function is faster then 2 abs functions and an if then else. Learn to use optimized code early and make it a habit or later you will regret it most likely.

moyack	Why not trying this: Code: set angle = Acos(Cos(angle)) This would set the angle in a positive value and this can help you to simplify the comparison.

Nenner	Thanks everyone, I tried something like what Troll-Brain suggested and it worked just fine!

the second abs is useless, cause you can simply do :
set real = 360 - real

But your solution don't work with my exemple.
I didn't try to optimize but just to make an easy way in gui.
something that he can understand easily

in my experience the "easy way in GUI" (or JASS for that matter) leads to hours upon hours of fixing code at a later date. And I don't understand what you mean my solution doesn't work? if you have |40-360| the answer is 320 thats the value he wanted... also i dont see what is hard to understand about absolute values "when you take the absolute value of a number and it is a negative number, then make that number positive to get the answer, if it is positive then that number is the answer"

I know how abs work >.<
No, he don't want 320 but 40 °. My english is too bad to explain why, sorry.

Not for this, hoppefully
