help me to..

[Vardan Petrosyan]

I make a plane, than poly extruded the Y value with rand($PR) what should I do next, so when I hit the play button it starts to animate those extruded peaces randomly? I type $F after that but its way to fast.

P.S. I'm a newbie

[gui]

if it's too fast, just divide $F for some value.

[edward]

probably $FF (floating frame) instead of $F (integer frame) though

[Vardan Petrosyan]

so i type rand($PR)*$FF and it raises, what symbol should I put before $FF? thanks for your patience

[Vardan Petrosyan]

I found something and typed sin($F*10) * rand($PR) and suddenly it worked almost as I wanted but I don't know why...

you can try

noise($TX, $TY+$T, $TZ)

and if you want to limit it just between 2 values you can use (for example 0.1 and 2)

fit11(noise($TX, $TY+$T, $TZ), 0.1, 2)

if you want to change speed just multiply $T with something

and here is the link that can be helpful for you

but as edward said don't use $F, use either $FF or $T (time in s)

As you said you don't know much about expressions, I will continue in a simpler way.

First, I think you must study more math, because your question is all about math.

If your animation is right, but too fast, just put "/x" after the expression you already have. where "x" stands for a number. But, you didn't tell us what effect you want to achieve. Just random extrusion? It's difficult to help you in the dark.

high level math? hm...
