Absolute Beginners Guide Part 9 - Functions

Absolute Beginners Guide Part 9 - Functions
Now that we're getting a hang of the basics, and understand variables, let's take a look at functions. Functions are ways to call a chunk of code to perform an action, and then we can get something back from that code, or it will do something for us that we need it to. Without functions, we can't go much further in our game journey, so let's dive in!

I has been awhile. I am happy to see you making new videos!

Hello. Meybe you make Tutorial: How make DRM for STEAM in GameMaker Studio 2 in GML? I don't see thats thema on youtube.

Informative, although way more elementary for me, but wanted to mention. Did you know that there is a limit to the number of arguments that you can use with functions with game maker. i believe the limit is 15 or 16. so no function can have more than that number of arguments.

[@LetsLearnThisTogether]

Good to know, I wasn’t aware there was a hard limit. You can use an array as an argument, so in that sense you could pass in an infinite amount, but you could only do 16 named arrays, so there’s that.

How do you make a script refer to another one? I Have set on playerObj create code that: coolDirection = 0, and i tried to create an objBullet. the speed of the objBullet is set to 2, and the direction is: direction = coolDirection so that would mean direction = 0 right? but when i actually press space to run it, it says coolDirection was not set.

[@LetsLearnThisTogether]

I’m not totally sure how your project is set up. A script is a function you write, and you can call them just any other function. When you call a custom function inside of another object, it can access its variables and data. So in a script you could set these values. If they’re not staying set, it sounds like another issue.

I have to admit at times I do wish you'd assume the viewer has a basic understanding of computers, because it threw me off to have to have "F1 on the keyboard" explained past just clicking it while we're having functions being explained too.

[@LetsLearnThisTogether]

Yeah, I understand, but this series is aimed at total beginners, and I assume you’re new to using real computers, too. I’ve found out recently that assuming someone knows how to right click, extract a file, or what function keys are can be dangerous. After this beginner series I’ll be doing something a little more advanced :)

@@LetsLearnThisTogether I understand! Keep going broham, I watch every single one of these!

I learned programming in math class so my functions are often named f1, f2, g1, etc. Sometimes if there would ever be a confusion, a couple extra syllables actually end up saving time for some viewers, especially beginners who might have never worked in an IDE before.
