Multiple comparisons at the same time

[marius]

Is it possible to do multiple comparisons of AVs and flags at the same time??
Like, I often check if an alterable value is between, say 5 and 20. My usual way would be to check if it is greater than 5 + lower than 20. But I have seen Max and Min before, though I have never used it myself and Im not 100% sure how it works..
Also, comparisons of flags: is it possible to compare multiple flags at the same time? If I remember correctly, you can check if a flag is off, and then enter the number as "0 and 1", which is a valid expression but a non working one - as far as I remember anyway..

You can use range in the form of (Value, Min, Max)

Alt.A = Range(Alt.A,5,20)

As for flags, I'm not sure what you're getting at. You can compare as many flags as you want in the same expression.

Flag 1 is off
+ Flag 2 is on
+ Flag 4 is off
-> Action

Something tells me that's not what you mean, though.

Cool! Ill try this out when I get home - thanks

As for flags, when you make a new event to check for a flag is on/off, in the expression you enter the flag, you are allowed to write "1 or 2". The event will say "Flag 1 or 2 is on" or "Flag 1 or 2 is off", but I dont think this expression works in reality.. I can post an example when I get home.

OR is a bitwise operator. Base level binary stuff. In binary, each digit is the following digit times 2, with the final digit being 1. The digits 00000 have the values 16-8-4-2-1. Making a digit 1 instead of 0 will "turn it on," adding the digit's number to the string's value. This "5-string" binary number can have the values 0-31, hence the 32 flag limit. Once you get to flag 32, you've wrapped back around to flag 0.

Flag 1 on would be 00001. Flag 2 on would be 00010. Flag 1 OR Flag 2 on would be 00011, also known as Flag 3.

i.e.:

Flag 3 = 00011
Flag 13 = 01101

OR: Produces a result of 0 in the digit if they're both 0. Otherwise, it's 1.

Flag 3 OR Flag 13 = 01111, a.k.a., Flag 15

AND: Multiplies the digits in each position.

Flag 3 AND Flag 13 = 00001, a.k.a., Flag 1

XOR: Results in a digit of 1 if they're different or 0 if they're the same.

Flag 3 XOR Flag 13 = 01110, a.k.a., Flag 14



I still think the only way to accomplish what you want is:

Flag 1 is on
+OR
+Flag 2 is on:
-> Action

I might also be misunderstanding, but I think he is saying the expression comparison of a flag is broken. Meaning, you can do a comparison in the expression editor and refer to a flag as a value of 0 (off) or 1 (on).

+ Flag ("active", 0) = 0 (using Compare 2 general values)
- do some action

In this comparison, if Flag 0 of "active" equals 0 (Flag 0 is off) then this condition returns true and some action occurs. It works fine for me when I test it out.

As for flags, when you make a new event to check for a flag is on/off, in the expression you enter the flag, you are allowed to write "1 or 2". The event will say "Flag 1 or 2 is on" or "Flag 1 or 2 is off"

I get the impression when fusion is asking him which flag to check, he's literally typing "1 or 2." This is a bitwise operation that's no different than putting in a formula, like 7-4. Putting "1 or 2" in the flag number will check flag 3.

mobichan, you gave me an idea though. You can get it done in one line with:

Compare 2 general values - Flag ("Active", 1) + Flag ("Active", 2) > 0:
-> Action

This will check if Flag 1 or Flag 2 is on. I generally try not to use compare 2 values though, because of scoping. But I can't think of any other way to get this done with one condition.
