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!

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.

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.

Then they're just gonna get hit with rocks and die, and die again 🙃. Post in the forum with a screenshot of your code and some hereo may rescue them. forum.gamemaker.io/index.php

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!

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?

Maybe there's a way to pass additional values to callback functions? Such as the item you're looking for

@GameMakerEngine Жыл бұрын

You can use method() to bind the callback method to a struct, that struct would hold the value you are looking for. Then you read that value in the function and use it as a predicate. Example function: function array_get_index(_array, _value) { static genericCallback = function(value, index) { return value == valueToSearch; } var specificCallback = method({ valueToSearch: _value}, genericCallback); return array_find_index(_array, specificCallback); }
