Must I write spaces between function parameters?
In a function definition, you must have a space between the [code]func[/code] keyword and the function name.

However, because we use the comma to separate parameters, it doesn't matter if you use spaces between parameters. As long as you have the comma, either syntax is correct.

We often use spaces after the comma for readability.
The following example defines a function that uses two parameters to move an entity on both the X and Y axes.
How should I name my functions and parameters?
The names of functions, parameters, or other things in your code are entirely up to you.

They are written by us programmers for other programmers. You want to use the names that make the most sense to you and fellow programmers.

You could absolutely write single-letter names like in maths classes: [code]a[/code], [code]b[/code], [code]f[/code].

You can also write abbreviated names like [code]pos[/code] for position, [code]bg[/code] for background, and so on.

Many programmers do either or both of the above.

At GDQuest, we favor complete and explicit names.

We generally try to write code that is explicit and relatively easy to read.

Right now, you have to enter every letter when you code, so long names may feel inconvenient.

However, this is good for learning: it trains your fingers to [ignore]type precisely.

Then, after you finish this course, you will see that the computer assists you a lot when you code real games with a feature called auto-completion.

Based on a few characters you [ignore]type, it will offer you to complete long names.

What's the correct syntax to define a function with multiple parameters?
You always write the function parameters inside of the parentheses. To define multiple parameters, you separate them with a comma.
