What is the best way to learn After Effects Expression

Hi,

 

I love After Effects to death. If am chosen by heaven and  it asks me what earthy things u want- I would say After effects and my cat. 

 

But the main villain in my love for  AE is the Expression 😐 .

 

No matter what I do it seems like a bottomless pit. I buy books, courses, print pdfs... I read expressions from websites... I do understand Expression, Though I have no foundation in coding. But when I want to do something on my own I can not write anythng! I can not write any code which can bring what I imagined into reality and it is taking its toll on my mental peace., beacuse am serious about it.

 

So, what is the best way to learn AE expression! I would be grateful if you could provide me some guidance.  😥I wanna be someone who can write AE expression like a pro.

 

Thank you 😥

Next exercise, draw a line 400px long oriented at 45° using createPath() in the path property of a shape layer with a stroke.

HELP: Use JavaScript to select point on a circle 

 

path expression:

 

lineLength = 400;
angle = 45;
p1 = [0, 0]; // first point poistion
pts = [p1]; // array of point coordinates

x = // Calcultate X position;
y = // Calcultate Y position;
pts.push(p1 + [x, y]);

createPath(pts, [], [], false)

I am so nervous.. Never had any acquaintance with createPath expression. I googled and tried to understand what it is and then tried to create the second homework.

The Youtube Channel, Animoplex, has a well-structured AE Expressions Course -

I recommend it to anyone who's keen to learn AE Expressions. And if you reach a stage where you want to go deeper, I've got a niche Advanced AE Course that uses Advanced Expressions.

We can give you small exercises to do:

 

1/ Create a square with a stroke
2/ Edit size and rotation expressions
3/ Duplicate the layer n times

 

size expression:

baseSize = 760;  // Base size of the square
layerIndex = index - 1;  // Adjusted layer index
reduction = 15;  // Size reduction per layer
s = // Calculate the size using the values mentioned above
[s, s]

 

rotation expression:

layerIndex = index - 1;
// Calculate the rotation using the value mentioned above

😮 What am supposed to write as 's' ? I have no clue! But my result  is different.
