Common Mistakes Beginners Make In GameMaker

Everyone makes mistakes, especially newbies. I know I've been there, and you probably have, too. Let's break down the most common mistakes that new game developers are making when it comes to GameMaker and how to fix them so you can get up and running once again.

Top 5 things I learned so far (I'm a GM2 beginner, but code veteran): - You gotta strike a balance between spamming events inside an object and listening to them (e.g. pressing a key) inside Step event. Too many events and one may end up dragging the others down or simply conflicting. Too little and your Step will be barely readable, not to mention debuggable. - Don't get too much ahead in coding. Take a time to wrap a feature and hit play. Play got a hotkey F5 for a reason. The longer you take to test something, the more difficult might be to spot a typo or simply make sure what you thought was going to work actually works. - Avoid assuming a function works in a different scenario other than the manual says. I'm looking at you, place_meeting(). I could blame Yoyo for delivering 4 different functions to the same purpose, but we gotta be smart about the tools they gave us and pick the right one. - Abuse place holders. Flat out abuse them. The more you can see, the less you'll miss. If you intend to make that boss the size of the room, simply do a stick-man and put there and figure it around your plans. Never assume it's gonna work AFTER you've done all the code gymnastics and have to backtrack what you've already coded. - Finally... This is more of a rant, but I think I'm doing something wrong. Wtf with these updates? Why do I have to uninstall and reinstall GM2 in order to update it? I mean, even the most brainless app in my phone is capable of simply updating the app (not sure it ever should need to, but...) GM2 can't? Maybe I'm missing some config, Idk

Thank you so much!!! My sprite was stretching and I had not a default background. After I add It it's working perfect!!!!

[@shubol3dgamer304]

I didn't do any of them except switching events. But I get to used two clicks very quickly. Didn't know it's possible set it to one click. Very useful. Thanks

Thank you Aaron, thank you so much for this videos, i'm italian and your english is perfectly clear, this means a lot to me

[@kenzyvaz7201]

Thanks a bunch sir!!!

[@pirateskeleton7828]

l have dabbled with both GMS2 and Unity. One of the things that threw me off in GML was knowing when I was passing a value or reference, since there is no strict type casting. For that, it helps to take a functional approach to functions, including returning structs, if your function figures out multiple values for you.

Great tips, very helpful!

[@jugibur2117]

Thanks! This "single click" on event clicks should be the default IMHO

Thank you so Much Mr Craig! Your videos put a smile on my face after I come back from school because its very rough there. These videos turn my day around and tysm!!

I’m glad to hear it :)

​@@LetsLearnThisTogethercould you help me with something please?

​​@@LetsLearnThisTogethermy npcs keep sinking under my tiles

[@LetsLearnThisTogether]

That sounds like an odd issue. If they’re sinking, then it sounds like you’re changing the depth of them and doing it incorrectly. Double check your depth doesn’t get altered below your tile layers.

Malformed variable on line 307 Great...

[@edwardperkins1225]

Most of them caused by GMS2's interface redesign. Not surprising at all.

What??? Who doesn't knows basic use of programs, so that he shouldn't use gamemaker or another game engine. This is very basic knowledge of computer skills. Maybe I'm old, but I remember times when everything was more difficult and everything I needed I've maked from scratch. This video can be apply for 99% users and programs nowadays. BTW your channel is otherwise great. :-)

[@BromYom]

I would never make a mistake in gamemaker so this video is not relevant at all

[@LetsLearnThisTogether]

100% true. I’ve got some of your GameMaker projects and they are flawless. Might show them off as examples as to how we should all code.
