Loop Array and Filter by String Prefix.

[Chazrox]

Can somebody help me figure out how to write a proper loop for this? My brain is so done rn. I need to create an array from all samplemaps, but grab only the ones with a specific prefix, i.e.
"KICKS_Kick 1", "KICKS_Kick 2" and populate them to a "KICKS" combobox.

I've tried for 3 hours. I want to jab my computer screen. lol.

@d-healey tbh that just confused me more. Theres too much going on in there.
I dont what im even looking at. I guess I have a bunch of studying to do. If thats what it takes to get what I need im probably not gonna get it any time soon. I thought it was a simple 1 liner added to whats usually needed to populate a combobox.

It's more complicated than that, but not too complicated.

Start simple. Loop over your array and console print each entry.

When you can do that, use substring and indexOf to print just the prefix.

When you can do that, try organising the entries into arrays based on their prefix.

Just go one step at a time until you know what you're doing. Everything is hard until it's easy.

@d-healey ok. Im not a quitter lol I'll be back. Thanks for the guidance!

[Chazrox]

@d-healey im stuck here because everything I try to print prints out to the console 3 times....

[Chazrox]

and this thing...

startOffset, stypeStrictness. I dont know what that is and I dont see it in the documentation so where do I even learn about this by myself? Please help me.

[Chazrox]

Im really trying to learn on my own but most of this stuff comes from you guys.

I learned ".length" from you guys but thats not even in the api's lol.

Where does that come from and what else is there where that comes from? lol

[rglides]

@Chazrox do you just mean content.getAllComponents("KICK");

this would get any component starting with KICK, best if you have names like KICK0, KICK1, KICK2 etc

and you can do an array like const var kicks = [KICK0, KICK1, KICK2, KICK3];

But maybe this isn't what you meant?

[rglides]

@rglides ah yeah me again not fully reading questions :D this doesn't directly help the combobox issue

[Chazrox]

@rglides haha all good brotha. Thank you! Im over here wrecking my brain. I've been at this one thing for 11 hours now. You know I thought I was smart until I came here hahahaha Bless! I love a good challenge but some things just need help and const var things = ME; //lol

You want String.indexOf rather than Array.indexOf - https://www.w3schools.com/jsref/jsref_indexof.asp

HISE Script is based on JavaScript so when it comes to basic functions you can often find the info you need by looking up the JavaScript equivalent.

My scripting 101 video might also be useful for you if you haven't seen it already.

@Chazrox haha I know the feeling!

this should work

@d-healey Thanks. I'm still sitting here trying. I've watched that video like 4 times in full and taken extensive notes but its just gonna take repetition to retain everything. It is alot. Loops are next level for me. I've figured out alot considering I have zero coding background and I've managed to finish a few plugins in my first month. This is considered advanced for me at the moment but i'll get it. I appreciate the help always! Im never asking for handouts!

see...there's ".length" in my OWN notes but I forgot I even wrote that. lol

[Chazrox]

@rglides part of me doesn't want to open this.....but I have to. LOL Im just trying to understand the logic. Thank You!

[rglides]

@Chazrox ha yeah it is really important to really learn it all, but snippets can help to learn, they can also soothe a headache sometimes lol

[Chazrox]

@rglides 100% !
