Question about Flags and the Flag Object

[Gullyking]

I was just wondering 'How many flags can an object have?' And also, the FLAG OBJECT: is it global? It would greatly increase the ease at creating my project, if it were. If not, I guess I'll create an 'active' global object and just use the flags from it. I'm assuming the number I'll need is somewhere in the hundreds.

32. I don't think it's global but I never really used it.

Why don't you setup a 2 frame application and test the flag object to see if it carries over to the next frame.

Good idea, Nivram. I'll check it out. I don't see a global check box in the properties of the object.

I don't normally use it either. However, I've created games with the RPGMaker before, perhaps you've heard of it. At any rate, it has a system known as 'switches' which come in two types, one of which is global. The flag part of MMF2 reminds me a lot of this system and I was thinking I could implement them much the same.

You can use Global Values and turn on/off each of the individual 32 bits in them:

AND is the bitwise 'and' operator, it checks two numbers, ie:
11010010
01000101
and then gives you a resulting number with only the bits on that were on in both:
01000000

OR is the bitwise 'or' operator, and it basically turns on the bits from both numbers, ie:
11010010
01000101
would give you:
11010111

Say you have a Global Value called Flags that will have many bits set (Global Values, as long as they are integers, can have 32 bits), and you want to get/set individual bits. First, lets say you want to turn on bit X:
Set Flags to Flags OR (2 pow
To Check if bit X is turned on:
(Compare Two General Values) Flags AND (2 pow > 0

X should be a number between 0 and 31.

That's mostly it. If you want more information on why and how this works, just ask.
