For the life of me, I have no idea what this is called. I don't even get why it has a := instead of just =. What is it? If I get the name of it, I can research what it does.
Thanks in advance.

var var_names := {
	player = 1,  # player must come first.
	air = 1,
	bullets = 10,
	tanks = 1,
	lives = 0,
	health = 1,
	keys = 0,
	level = 1,
	}

Here are two examples that illustrate this operator. Both examples have the same error (multiplying a string by a number). But the first example produces a runtime error, while the second one produces a compile-time error (which is better).

var s = "hello"
print(s * 2)
var s := "hello"
print(s * 2)

spacecloud Should I mention you in the YouTube video I was doing on this? I was going to show how to save and load multiple objects. You did help me discover this, as this method is actually used- as seen in the small bit of code at the top.
