How to reassign a variable's class
Hi, I've got an instance where I need to change the class of a variable so that it could be one of two classes. How would I do this?
var aVar;
var aNum:int;
if(aNumb == 1)
{
// aVar gets class 'fish'
}
else if(aNumb == 2)
{
// aVar gets class 'bird'
}
Make a common superclass, like 'animal' and derive 'fish' and 'bird' from 'animal' Then if the var is of type 'animal' it should accept 'fish' or 'bird'
untested:
class Animal ( can add 'extends MonoBehaviour' here if it would be such a thing)
{
var legs : int; // for example
}
class Bird implements Animal
{
Bird() { legs = 2; } // constructor to initialize whatever
}
class Fish implements Animal
{
Fish() { legs = 0; }
}
var f : Fish = new Fish();
var b : Bird = new Bird();
var a : Animal;
a = f;
a = b;
When I put 'implements' it gives an error and asks if I meant 'extends' does that make sense? I'm using Java Script if it helps.
It doesn't work for me. Did you change something in the code that DaveA provided (apart changing "implements" to "extends")?
