Frage von Blackeagle123:


Hello,

I have an expression for my size. I would like to wiggle with the size of "dancing" can.

Now I have the problem that the proportions are not maintained, although the hooks (or snake) in the box in front of the scale variable is enabled.

What should I change to ...

a) ... both the same variable to change?
b) ... only the x coordinates with the wiggle-command to change?
c) ... only the y-coordinate by Wiggle to change?

Thanks in advance!

Liebe Grüße,
Constantin



Antwort von kriss:

Hi
a) w = wiggle (3.50);
[w [0], w [0]]

b) w = wiggle (3.50);
[w [0], value [1]]

c) w = wiggle (3.50);
[value [0], w [1]]



Antwort von Blackeagle123:

wow, thank you! Funtkioniert super.

Small question about the expression:
Is the "w" an arbitrarily chosen variable? Or is there a set AfterFX in importance?

And tell me what the values in the brackets? [0], and tell me what "value [1]"?

Thank you in advance in advance!

Liebe Grüße,
Constantin

Is it synonymous, but please read the manual.

Arrays. The number indicates the position of the element in the array.

Antwort von Blackeagle123:

Mhmm ... I understand the reason simply put this line here yet:

Quote: [value [0], w [1]]

What an array, I know. (At least in other programming languages)
But where the position in the array is defined, I do not know where or "value" is defined.

"value" is a reserved keyword for the current stream Property before the expression is applied. Does not matter what the straight sets while its syntax is correct.
