enum

How does it work?
I've used it before, but I can't remember how now.

enum MODE{"FOLLOW","STAY","ATTACK"};
enum MODE{FOLLOW,STAY,ATTACK};
MODE.FOLLOW;
this.action = MODE.FOLLOW;

Help? I have no clue how it works.

I'm not sure how Graal does it, but I think in C++ an enumeration is a word constant for numbers, in your example, follow would be 0, stay as 1, and attack as 2 and so on. But this isn't the format I've seen it in, I've never seen using mode.follow or the MODE at the front of the enumeration, so I could be very wrong XD

From what I remember about enumerated types, that would give this.action the value of 0. (this.action = MODE.ATTACK //this.action is 2).

It's used mostly so that you don't have to remember '2' means attack. You can just use MODE.ATTACK instead.

Examples:

PHP Code:


		
			
enum foo{a, b, c};

is sort of like:

PHP Code:


		
			
foo.a = 0;

foo.b = 1;

foo.c = 2;

You can also do:

PHP Code:


		
			
enum foo{a = 4, b = 8, c = 10}; //4, 8, 10 are arbitrary

Which is like:

PHP Code:


		
			
foo.a = 4;

foo.b = 8;

foo.c = 10;

MODE.IDLE, with value 0

Also.
