Question

Can you use an object’s existence as the condition of an if statement in Haxe? If so, how?

var b : Bullet = collide("bullet", x, y);
if (b) {
  b.destroy();
}

I’ve also tried testing it against the Null type, but that doesn’t seem to work.

As kirilloid mentions in the comments, try checking if b is not null:

var b : Bullet = collide("bullet", x, y);
if (b != null) {
  b.destroy();
}

It was decided for Haxe not to have the if(b) syntax for a number of reasons. You can find a discussion on the topic on Google Groups: Test if exists.
