enum choose Random :)
Got this
enum State { Left, Right }
void Start() { //Wanna make this state choose a random State from State. :P So somethimes its left other times its right.... state = State.Left; }
Since it's just two choices:
state = Random.value < .5 ? State.Left : State.Right;
Thx m8 worked just fine :) And thx to others too, Tried "state = GetRandomEnum();"
But didnt work.
Just a note: if you have more than two choices, you could use casting, but you should make sure you know the $$anonymous$$ and max values of the enums, and that there are no 'holes' in the sequence.
Well the two solutions here will work in your case, but since enums are not restricted to sequential values here's a general approach (C#):
I just wrote a little generic helper function that will select a random enum member.
static T GetRandomEnum<T>()
{
System.Array A = System.Enum.GetValues(typeof(T));
T V = (T)A.GetValue(UnityEngine.Random.Range(0,A.Length));
return V;
}
And here's a little example:
enum MyEnum { Dog = 1, Cat = 2, Cow = 502, Bird = 621 }
MyEnum choice = GetRandomEnum<MyEnum>();
And in your case you could do:
state = GetRandomEnum<State>();
could you please explain this a bit, mostly what the T means in static T GetRandomEnum()
it works but I do not know what the T is for and why a static is required ins$$anonymous$$d of a class.
@Dark_$$anonymous$$oo: This is a generic function. The type-parameter T allows the function to work with different types ins$$anonymous$$d of one. The return type of the function (which is T) will vary on how you call the function.
Unity has also a page which explains generic methods briefly
This is a good answer to the general problem. Thanks!
Give this a bash.
EDIT: Added + 1 to the Max parameter of Random.Range(), as per Peter's comment.
state = Random.Range((int)State.Left, (int)State.Right + 1);
Random.Range() is exclusive on the max value, so it will never be chosen if you do that.
Thx all :) DaveA answer did the job..
