How To Use Array Functions in GML | GameMaker

The new array functions introduced in 2022.11 make it easier and powerful to edit arrays and find things.

Everything you need to take your idea from concept to finished game. With no barriers to entry and powerful functionality, GameMaker is the ultimate 2D development environment!

GM please give this man a raise-- his content is the best out there in terms of quality & concision. I appreciate these intermediate level tutorials and think we need more content directed at this level.

Was trying to use array_find_index using the manual and couldn't figure it. Got the index I needed to delete, thanks so much!

The arrays in GM are basically array heaven

Thanks for this video.
It was, for me, a bit difficult to use "array_find_index" the way I wanted to - with struct in my array.

Would have been nice if someone explains how to use array_find_index with more complex objects like objects or structs. This seems to be way more complicated than one would think when it comes to simple functions for getting indexes. I am not the only person with the same problem judging by the other comments.

I have a hard time wrapping my head around array_find_index() - How would you use it to find an a specific item you are looking for? In the example, "sword" is hard-coded into the predicate function. How do you find the index if what you are looking for is decided during runtime, not compile time?

Finally! I'm mainly a Javascript developer and I am really glad GMS2 introduced the equivalents of filter, map, foreach and such.

I have latest version and it seems like these new array functions doesnt exist/show in my IDE (If I write "array_map", it is shown as a new variable), do you know what possibly be the issue and how could I solve it? Thanks!

Now I can put my JS knowledge to use...

Can you guys make a tutorial how to use the coding language

Please give us GUI tools so godot users stop laughing at us

Are you all going to convert gml to just be javascript one day? Cause I'm fine with that.
