	English	Actions
	In your code, values have a particular [i]type[/i]. You have already learned about several: whole numbers, decimal numbers, strings, 2D vectors, arrays, and dictionaries. The computer uses the type of a value to know which operations and functions you can use with them. As a result, it's essential to understand types: they are not fully compatible with one another, and misusing them will cause errors.
	A prime example
	You want to display the player's health in the interface. Your code tracks health as a whole number, a value of type [code]int[/code] (short for integer).
	However, to display it on the player's screen, the computer wants text: it needs a value of type [code]String[/code]. You can concatenate two strings with the [code]+[/code] operator.
	So the following code looks like it could work at first glance.
	But when running the code, we get this strange error.
	It tells you you can't add values of type [code]String[/code] and [code]int[/code]: they're incompatible. In that case, you need to convert the [code]health[/code] number into a [code]String[/code].
