The quality of content in this channel is NUTS! 💯

[@Animoplex]

Thanks for the praise! Quality is my top priority.

[@avnishsingh4950]

brilliant! keep em coming

[@Animoplex]

You got it! More coming in the next couple of weeks, recording this weekend and edits will come shortly after.

[@flutterlight5823]

just amazing content. one thing, while are talking, also are controlling the animation flow, how do you do control that? please!

[@Animoplex]

Can you elaborate what you mean by animation flow?

[@hasanalasim]

@@Animoplex I mean, how do maintain both animations and voice in videos? do you record voice first then create the animation according to what you're saying like that??

[@Ken-kj3yq]

Awesome, keep it up!

[@Animoplex]

Thanks, will do!

[@richochet]

Hey thanks! What is the control layer? How do I recreate it?

[@Animoplex]

You're welcome! You can create a control layer using a Solid, a Null, or a Shape layer. There's not really a specific Control layer, you can choose how you make one!

@@Animoplex Thank you!

I'm looking for an answer to something in particular. What about the array indexOf? Doesn't work in AE.

[@Animoplex]

Not sure it’s supported. Have you tried in the new CC19 expression engine? Might be worth a look. What are you trying to accomplish with indexOf? There may be an alternative workaround.

[@angelmolinalopez9997]

@@Animoplex I've been looking for some information and, indeed, it's a unsupported feature. Eventually, I realized I could simplify my expression but it's a bit stupid that this feature is not included. At least in my version.

[@Animoplex]

Glad you got a workaround figured out. Put in a feature request for the AE team :)

so i still dont get what array is used for? why we use square brackets not parenthesis or uhh round brackets. i dont get people who knows how to code. they are not very straight forward to udnerstand.

[@Animoplex]

Square brackets surround array indices, and that's part of the ActionScript and JavaScript syntax. Parenthesis and curly brackets are also used for specific purposes. At the end of the day, they are all tools you can use to make coding easier. If you want to learn more about the syntax and why these were chosen, a fundamental JavaScript course might helpful. Hope this helps!

Can someone explain to me why if I use a wiggle it breaks my expression(this being a 2d layer). Example Below; wig = wiggle(2,250); [value[0], value[1] + wig] Thanks in advance for any help, just trying to understand why it breaks. I know I can do the following for it to work but not sure why it works. wig = wiggle(2,250); [value[0], wig[1]]

[@Animoplex]

In your example, you'll have to specify the index of wiggle that you'd like to use. Right now, you are creating a variable called wig but not referencing it in your expression. Wiggle also outputs the same number of dimensions as the property it's applied to, so make sure to include [0] or [1] after wig. You'll want to change this line: [value[0], value[1] + wiggle] to this: [value[0], value[1] + wig[1]] Hope this helps!

[@andydreadsbmx]

I think i figured it out, correct me if I'm wrong. I cannot add a the wiggle because its modifying a value and does not actually have a value to add.

[@Animoplex]

That is correct, you'll want to add something other than value to affect it, either a Slider Control or reference to another property. Just make sure you reference wig (instead of wiggle) in your expression from earlier and be sure to include the right index [0] or [1] or [2] depending on the wiggle value you want to manipulate.

[@andydreadsbmx]

That makes sense, thanks for the quick reply!!

[@nikolasgarcianikomanga]

Hi, is there a way to get the length of and array? I tried with position.length but it does not work. Apparently it only works with texts.

[@Animoplex]

Try: position.value.length

[@nikolasgarcianikomanga]

@@Animoplex thank you !!

[@Dinesh66263]

how to separate dimensions for scale......?
